Description

[Technical field]

[0001] The present invention relates to a timepiece having a rotating bezel. [Background technology]

[0002] A rotating bezel-equipped timepiece, such as a diver's watch, has been known for some time. A rotating bezel is a rotatable bezel attached around a crystal cover, and a scale corresponding to the hands of the timepiece is displayed on the surface of the bezel. With such a rotating bezel, the relationship between the scale and the hands can be set by rotating it appropriately, allowing the user to easily read the elapsed time from a certain point in time. Among such watches with rotating bezels, there is known a watch in which a click groove is formed on the back side of the rotating bezel and a leaf spring member is attached to the case side of the watch (see Patent Document 1). In this watch, by engaging the leaf spring member with the click groove, a clicking sensation is obtained when the rotating bezel is rotated, and the rotating bezel can be prevented from rotating in the reverse direction.

[0003] [Patent Document 1] JP 2015-108512 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the timepiece of Patent Document 1 does not disclose adjusting the click force to improve the click feeling or the reverse rotation prevention effect. If the click force is adjusted in the timepiece of Patent Document 1, it is necessary to adjust the elastic force of the leaf spring member that engages with the click groove. Here, it is considered to adjust the elastic force by changing the plate thickness of the leaf spring member, but this increases costs because multiple types of leaf springs with different plate thicknesses must be prepared, and furthermore, changing the leaf spring member causes a large change in the elastic force, making it difficult to appropriately adjust the click force. It is also possible to adjust the click force by changing the protruding dimension of the leaf spring member that engages with the click groove, but this requires changing the height dimension from the groove where the leaf spring member on the case is attached to the click groove in the rotating bezel.If the number of case types increases or the depth of the groove is increased, the height position of the rotating bezel must also be changed so that it does not interfere with the groove, posing the problem that the thickness of the watch cannot be reduced, making it difficult to make the watch thinner. [Means for solving the problem]

[0005] The timepiece of the present disclosure has a rotating bezel and a holding member that rotatably holds the rotating bezel, the holding member having a case and a rotating bezel pressing ring that is fixed to the case and holds the rotating bezel between the case and the case, and one of the holding member and the rotating bezel is provided with an annular restricting portion having a plurality of restricting receiving portions that are continuous in the circumferential direction, and the other of the holding member and the rotating bezel is provided with a restricting member that engages with the restricting receiving portions to restrict the rotation of the rotating bezel, and an abutting member that abuts against the restricting member. The regulating member comprises a base rotatably attached to either the holding member or the rotating bezel, an engagement portion that engages with the regulating receiving portion, and a biasing portion that extends to the opposite side of the engagement portion across the base and is formed in an elongated shape, and generates a biasing force that biases the engagement portion toward the regulating receiving portion by abutting against the abutment member and elastically deforming, and the abutment member is configured to be able to change the magnitude of the biasing force generated by the biasing portion by changing the position at which it abuts against the biasing portion.

[0007] [First embodiment] Below, a timepiece 1 with a rotating bezel according to a first embodiment will be explained with reference to the drawings. Fig. 1 is a front view of a timepiece 1 of a first embodiment, Fig. 2 is a cross-sectional view of the timepiece 1, Fig. 3 is a plan view showing the main parts of the timepiece 1, and Fig. 4 is an exploded perspective view showing the exterior parts of the timepiece 1. As shown in Figures 1 and 2, the watch 1 is a diver's watch used by divers diving underwater etc. The watch 1 is equipped with a circular dial 2 as a display section for displaying the time, an hour hand 21, a minute hand 22, a second hand 23, a date wheel 24, a power reserve hand 25, a movement 10, a case 3 that houses the movement 10 inside, a band 4 for wearing, a crown 5 for setting the time etc., a rotating bezel retaining ring 6 attached to the case 3, and a ring-shaped rotating bezel 7 rotatably provided on the case 3.

[0008] As shown in Fig. 2, the case 3 comprises a body 31, a back cover 32, and a crystal 33. The body 31 is formed in a substantially cylindrical shape, and a cylindrical holder 310 is formed at the upper end (the side facing the watch) of the body 31. The crystal 33 is attached to the inner peripheral surface of the holder 310 via a ring-shaped packing 34. As also shown in Fig. 4, the outer peripheral surface of the holder 310 is formed with a male thread 311 into which a rotating bezel retaining ring 6, which will be described later, is screwed. The body 31 also comprises an upper surface 314 formed on the outer peripheral side of the holder 310, which faces the back surface of the rotating bezel 7, which will be described later. 2, a female thread 312 is formed on the lower end of the inner circumferential surface of case 31 (the back side of the watch), and a male thread 321 formed on back cover 32 is screwed into female thread 312. Therefore, back cover 32 is removably attached to case 31. In addition, a ring-shaped packing 35 is arranged between case 31 and back cover 32.

[0009] The case 3 contains the dial 2, hour hand 21, minute hand 22, second hand 23, date wheel 24, power reserve hand 25, and movement 10. The movement 10 of this embodiment has a spring that displays the duration with the power reserve hand 25. In other words, the movement 10 is a movement for an electronically controlled mechanical timepiece having a gear train, a spring, a regulator / generator, etc., or a movement for a mechanical timepiece having a gear train, a spring, an escapement, etc. The movement 10 may also be a movement for an electronic timepiece having a gear train, a step motor, a battery, etc.

[0010] [Rotating bezel retaining ring] As also shown in Figure 4, the rotating bezel retaining ring 6 comprises a ring body 60 formed in a circular ring shape, a spanner groove 61 formed on the upper surface of the ring body 60, a female thread portion 62 formed on the inner surface of the ring body 60, and a protrusion 63 formed so as to protrude outward from the outer circumferential surface of the ring body 60.

[0011] The spanner grooves 61 are formed at six locations at 60° intervals on the upper surface of the ring body 60. This allows the rotating bezel pressing ring 6 to be attached to or removed from the case 31 by using a screw back opener, which is used when attaching or removing a screw-type back cover, to rotate the ring with two or three claws engaged with the spanner grooves 61. Note that the number of spanner grooves 61 is not limited to six, and it may be formed in, for example, two or more locations. In addition, the structure for rotating the rotating bezel pressing ring 6 is not limited to one that has the spanner grooves 61. For example, a jig that matches the regulating receiving portion 64A described later may be created, and the jig may be engaged with the regulating receiving portion 64A to rotate the rotating bezel pressing ring 6. The female thread portion 62 is formed on the inner peripheral surface of the ring body 60 so as to be screwed into the male thread portion 311 of the holding portion 310 .

[0012] 2, the height dimension of the protrusion 63, i.e., the dimension in the thickness direction of the watch 1, is smaller than the height dimension of the ring body 60, and the protrusion 63 is formed in the middle of the ring body 60 in the thickness direction of the watch 1. The lower surface of the protrusion 63 is formed higher than the lower surface of the ring body 60, i.e., on the watch surface side. As a result, when the rotating bezel pressing ring 6 is screwed into the holding part 310 and attached, a recessed groove of a predetermined height dimension is defined between the upper surface 314 of the case 31 and the protrusion 63. The rotating bezel 7 is placed in the recessed groove between the upper surface 314 of the case 31 and the protrusion 63, and is held so that it can rotate without falling off the case 31 or the rotating bezel pressing ring 6. The upper surface of protrusion 63 is formed below the upper surface of ring body 60, that is, on the back side of the watch. As a result, the upper surface of protrusion 63 is located below the bottom surface of spanner groove 61, and is configured not to affect protrusion 63 when spanner groove 61 is machined by cutting the upper surface of ring body 60.

[0013] 3 and 4, a circular restriction portion 64 is formed along the circumferential direction on the outer peripheral surface of the protruding portion 63. The circular restriction portion 64 has a plurality of restriction receiving portions 64A formed continuously in the circumferential direction. In this embodiment, 60 restriction receiving portions 64A are formed in the circumferential direction of the rotating bezel pressing ring 6. Therefore, the restriction receiving portions 64A are formed at a central angle of 6° in the circumferential direction of the rotating bezel pressing ring 6. As shown in the enlarged view of Fig. 5, the restriction receiving portion 64A has a restriction surface 65 and a guide surface 66. The restriction surface 65 is a surface formed along the diameter direction of the ring body 60, and is provided at a central angle of 6°. In Fig. 5, A1 is the opposite direction to the movement direction of the hands such as the minute hand 22, i.e., the counterclockwise direction, when the watch 1 is viewed from the front side, and A2 is the clockwise direction. The counterclockwise direction A1 is the first direction, and the clockwise direction A2 is the second direction. The guide surface 66 includes an inner peripheral surface 661 that is continuous with the inner peripheral edge of the regulating surface 65, an inclined surface 662 that is continuous obliquely from the end of the inner peripheral surface 661 in the counterclockwise direction A1 toward the counterclockwise outer periphery, and an outer peripheral surface 663 that is continuous in the counterclockwise direction A1 from the outer peripheral end of the inclined surface 662. The edge of the outer peripheral surface 663 in the counterclockwise direction A1 is continuous with the outer peripheral edge of the next regulating surface 65. As a result, the regulating receiving portion 64A has a tooth portion 67 that is defined by the regulating surface 65, the outer peripheral surface 663, and the inclined surface 662 and protrudes toward the outer periphery, and a groove portion 68 that is defined by the regulating surface 65, the inner peripheral surface 661, and the inclined surface 662 and recessed toward the inner periphery.

[0014] [Rotating bezel] As shown in FIGS. 1 to 4, the rotating bezel 7 is disposed around the holder 310 of the case 31 and the cover crystal 33, and is provided so as to be freely rotatable relative to the case 31. The rotating bezel 7 is configured to include a bezel main body 70 formed in an annular (ring-shaped) shape, a display plate 80 also formed in an annular shape, and a click spring 90 which is a regulating member.

[0015] [Bezel body] 2 and 4, the bezel body 70 is a substantially annular member made of a metal material, and includes a base portion 71 that faces the upper surface 314 of the case 31, and an outer circumferential portion 72 that is formed rising from the outer circumferential side of the base portion 71. An operating portion 73 having projections and recesses arranged in the circumferential direction is formed on the outer circumferential surface of the outer circumferential portion 72. The base portion 71 is disposed along the upper surface 314 of the case 31, and its inner peripheral end portion is disposed between the protruding portion 63 of the rotating bezel pressing ring 6 and the upper surface 314. In this case, the thickness dimension of the base portion 71 is made smaller than the height dimension from the lower surface of the ring body 60 to the lower surface of the protruding portion 63 of the rotating bezel pressing ring 6. Therefore, when the bezel body 70 is disposed on the outer periphery side of the holding portion 310 and the rotating bezel pressing ring 6 is screwed into the holding portion 310, the movement of the bezel body 70 upward, i.e., toward the watch face, is restricted by the protruding portion 63, and the bezel body 70 is provided rotatably with respect to the case 31 and the rotating bezel pressing ring 6. Therefore, the case 31 and the rotating bezel pressing ring 6 form a holding member that rotatably holds the rotating bezel 7.

[0016] 4, the base portion 71 is formed with a screw hole 75 into which a screw 95 for rotatably mounting the click spring 90 is screwed, and a mounting hole 76 for mounting a pin 96 which is an abutment member that abuts against the click spring 90. The screw hole 75 is formed penetrating the base portion 71 in the clockwise thickness direction, and is formed at one location in the circumferential direction of the base portion 71, and in this embodiment, is formed on the side of approximately the 12 o'clock position, as shown in FIG. The mounting hole 76 is formed penetrating the base portion 71 in the clockwise thickness direction, and is formed at a position a predetermined distance away from the screw hole 75, approximately on the 10 o'clock side in this embodiment. Furthermore, the mounting hole 76 is an elongated hole along the circumferential direction of the base portion 71. The mounting hole 76 is also configured so that the pin 96 can be press-fitted and fixed within the range of the mounting hole 76. This allows the mounting position of the pin 96 to be set along the circumferential direction within the elongated hole, and is also changeable. Therefore, the mounting hole 76 is an elongated hole in which the pin 96, which is an abutting member, can be installed, and is formed so that the installation position of the pin 96 can be changed at least in the circumferential direction. The positions at which the screw holes 75 and the mounting holes 76 are formed are not limited to the example of this embodiment, and can be set at any position on the circumference of the base portion 71.

[0017] As shown in FIG. 2, the upper side of the outer circumferential portion 72 protrudes slightly toward the inner circumferential side, and a display plate 80 is press-fitted and fixed to the inner circumferential surface of this protruding portion with a ring-shaped packing 77 sandwiched therebetween. A packing 78 is also disposed between the bezel body 70 and the case 31. By providing this packing 78, the sliding property of the rotating bezel 7 can be improved, and the rotating bezel 7 can be rotated smoothly. Furthermore, the base portion 71 of the bezel body 70 is pushed upward by the packing 78 and abuts against the lower surface of the protruding portion 63, so that the bezel body 70 rotates stably without rattling when operated by the user. Furthermore, when the user is not operating the bezel body 70, the click spring 90 engages with the rotating bezel pressing ring 6 to hold the bezel body 70 in the circumferential direction, and the packing 78 abuts the base portion 71 against the protruding portion 63 to hold the bezel body 70 in the thickness direction of the watch. It is possible to improve sliding properties by disposing a sheet material instead of the packing 78. Also, if the sliding properties of the rotating bezel 7 can be improved or rattling can be prevented by improving the machining precision of each part or by performing surface treatment such as ion plating, a configuration without providing parts such as the packing 78 between the bezel main body 70 and the case 31 is possible.

[0018] [Display board] As shown in FIG. 2, the display plate 80 includes a circular display portion 81 and a press-fit portion 82 that protrudes from the lower surface of the display portion 81 and is press-fitted into the inner periphery of the outer periphery portion 72 with the packing 77 sandwiched therebetween. 1 and 4, a start mark 811 and minute scale 812 indicated by minute hand 22 are indicated on the surface of display unit 81. The watch 1 of this embodiment is a diver's watch, and by aligning start mark 811 of display unit 81 with the position indicated by minute hand 22 at the start of a dive, the elapsed time from the start of the dive can be confirmed by the minute scale 812 indicated by minute hand 22. The lower surface of the press-fit portion 82 is disposed above and spaced from the base portion 71, and a click spring 90 is disposed in the space between the base portion 71 and the press-fit portion 82.

[0019] [Click spring] As shown in Figures 4 and 5, the click spring 90 is composed of a long, thin plate material and has a base 91, an engagement portion 92 formed at one end of the base 91 and capable of engaging with the regulating portion 64A of the rotating bezel retaining ring 6, and a biasing portion 93 extending from the base 91 in a direction generally opposite the engagement portion 92 and having a tip that abuts against the pin 96. The base 91 is formed with a hole 911 through which a screw 95 is inserted. The screw 95 is a shoulder screw having a threaded portion that screws into the threaded hole 75 of the base 71 and a shaft portion that is disposed in the hole 911. Therefore, the base 91, i.e., the click spring 90, is rotatably attached to the base 71 by the screw 95, which is a rotating shaft member. Note that the click spring 90 may be rotatably attached to the base 71 by a fixing pin or rivet instead of the screw 95. The base 91 has a width larger than that of the biasing portion 93, and is strong enough not to deform even when the engaging portion 92 formed at the tip of the base 91 engages with the restriction receiving portion 64A. The tip side of the base 91 is formed with a first contact surface 921 that contacts the inner circumferential surface 661 of the restriction receiving portion 64A, a second contact surface 922 that contacts the restriction surface 65 of the restriction receiving portion 64A, and a third contact surface 923 that is provided continuously from the first contact surface 921. The engagement portion 92 formed at the tip of the base portion 91 is configured as a corner portion defined by a first abutment surface 921 and a second abutment surface 922. The intersection angle between the first abutment surface 921 and the second abutment surface 922 is an acute angle less than 90°, for example, 82°. Moreover, the intersection angle between the first abutment surface 921 and the third abutment surface 923 is an obtuse angle, for example, 168°.

[0020] The biasing portion 93 is provided on the opposite side of the engaging portion 92 with the screw 95 in between, and is configured so that its width dimension decreases with increasing distance from the base portion 91, with its tip abutting against the side surface of the pin 96. Note that when the engaging portion 92 of the click spring 90 abuts against the corner portion where the inner circumferential surface 661 and the regulating surface 65 intersect, and the pin 96 is not provided, the tip side of the biasing portion 93 is configured to overlap, in a plan view, with the mounting hole 76 into which the pin 96 is press-fitted, as shown by the two-dot chain line in FIG. 5, when the pin 96 is attached to the attachment hole 76 and the tip of the urging portion 93 is in contact with the outer periphery of the pin 96, the urging portion 93 is elastically deformed and slightly curved. Due to the elastic force generated by the deformation of the urging portion 93, the engagement portion 92 is urged toward the inner periphery surface 661 and is brought into pressure contact with the restriction surface 65 and the corners of the inner periphery surface 661, thereby restricting the rotation of the rotatable bezel 7 relative to the rotatable bezel pressing ring 6 in the clockwise direction A2, i.e., the second direction.

[0021] The material of each part can be selected appropriately. In this embodiment, the body 31 of the case 3, the back cover 32, the bezel body 70 of the rotating bezel 7, and the rotating bezel pressing ring 6 are made of titanium, and the click spring 90, which is a restricting member, is made of stainless steel. However, all parts may be made of stainless steel. If the rotating bezel pressing ring 6 is made of titanium and the click spring 90 is made of stainless steel, durability can be improved compared to when both are made of titanium. Furthermore, the rotating bezel pressing ring 6 may be plated by ion plating or the like. Plating can improve sliding properties and reduce friction when the click spring 90 moves while in contact with the guide surface 66, allowing the rotating bezel 7 to be rotated smoothly.

[0022] Next, the operation of the click spring 90 when the rotatable bezel 7 is rotated in the counterclockwise direction A1, which is the first direction, will be described with reference to FIGS. 6A to 6C. 6A, when the engaging portion 92 engages with the groove portion 68, the tip of the biasing portion 93 abuts against the pin 96, so that the engaging portion 92 is biased toward the inner periphery of the rotatable bezel pressing ring 6, i.e., toward the inner circumferential surface 661. Since the intersection angle between the first abutment surface 921 and the second abutment surface 922 of the engaging portion 92 is an acute angle, the tip of the engaging portion 92 presses against the corner where the inner circumferential surface 661 of the groove portion 68 and the regulating surface 65 intersect, and rotation of the rotatable bezel 7 in the clockwise direction A2 can be reliably regulated. Furthermore, a third abutment surface 923 is provided which is continuous with the first abutment surface 921, and is configured so that when the engagement portion 92 is engaged with the groove portion 68, the third abutment surface 923 does not abut against the inclined surface 662. This prevents the first abutment surface 921 of the engagement portion 92 from moving away from the inner surface 661, and reliably maintains the state in which the rotation of the rotating bezel 7 is restricted by the engagement portion 92.

[0023] Next, when a user of the timepiece 1 grasps the operating unit 73 and rotates the rotating bezel 7 in the counterclockwise direction A1, the click spring 90 also moves in the counterclockwise direction A1 relative to the rotating bezel pressing ring 6, and the third contact surface 923 comes into contact with the outer circumferential edge of the inclined surface 662. As a result, as shown in FIG. 6B, the engagement portion 92 of the click spring 90 moves in a direction away from the rotating bezel pressing ring 6, that is, toward the outer circumferential side, and the base portion 91 on which the engagement portion 92 is formed also rotates toward the outer circumferential side with the screw 95 as the rotation axis. At this time, the biasing portion 93 in contact with the pin 96 is deflected to a greater extent, and the force that tries to return this deflection, that is, the elastic force, increases the biasing force with which the engagement portion 92 comes into contact with the rotating bezel pressing ring 6. As the rotating bezel 7 rotates in the counterclockwise direction A1, the third contact surface 923 contacts the inclined surface 662 of the restriction receiving portion 64A, and the first contact surface 921 contacts the outer circumferential surface 663 of the restriction receiving portion 64A. As a result, the engagement portion 92 of the click spring 90 is released from the groove portion 68.

[0024] When the rotating bezel 7 is further rotated in the counterclockwise direction A1, the engagement portion 92 of the click spring 90 engages with the next groove portion 68, as shown in Fig. 6C. At this time, the engagement portion 92 comes off the outer peripheral surface 663 and abuts against the inner peripheral surface 661 while being subjected to the biasing force generated by the bending of the biasing portion 93, generating a click sound. In addition, the engagement portion 92 abuts against the restriction surface 65, so that the rotation of the rotating bezel 7 in the clockwise direction A2 is restricted. For this reason, when the rotatable bezel 7 is rotated in the counterclockwise direction A1, each time the click spring 90 moves from the groove portion 68 over the tooth portion 67 and engages with the next groove portion 68, a click sound is generated and the rotation of the rotatable bezel 7 in the clockwise direction A2 is restricted. In addition, since the click spring 90 moves in the counterclockwise direction A1 together with the rotatable bezel 7, the location where the click sound is generated also moves sequentially around the dial 2 in the counterclockwise direction A1.

[0025] With the above-described configuration, when the user grasps and rotates the operation portion 73 of the rotating bezel 7, the rotating bezel 7 including the display plate 80 can be rotated as a unit in the counterclockwise direction. When the rotating bezel 7 is rotated relative to the case 3, the biasing portion 93 of the click spring 90 elastically deforms, and the engaging portion 92 disengages from the groove portion 68 of the regulated receiving portion 64A with which it was engaged, and engages with the groove portion 68 of the next regulated receiving portion 64A. As a result, a clicking sensation is obtained when the rotating bezel 7 is operated as the rotating bezel 7 rotates, and the click spring 90 sequentially engages with the 60 regulated receiving portions 64A, so that the rotating bezel 7 can be held in that position every time the rotating bezel 7 is rotated by 6°.

[0026] 5 and 6A to 6C, the position of the pin 96 can be changed to the clockwise direction A2, that is, closer to the screw 95, as shown in Figures 7A to 7C. In this way, when the distance between the screw 95 and the pin 96 is shortened, a larger force is required to deform the biasing portion 93, and therefore, when the rotating bezel 7 is rotated in the counterclockwise direction A1, the biasing force applied to the rotating bezel pressing ring 6 by the engagement portion 92, that is, the click force, becomes larger. 5 and 6A to 6C, the position of the pin 96 can be changed in the counterclockwise direction A1, that is, away from the screw 95, by increasing the distance between the screw 95 and the pin 96. In this way, by increasing the distance between the screw 95 and the pin 96, the force required to deform the biasing portion 93 can be reduced, and the biasing force applied to the rotating bezel retaining ring 6 by the engagement portion 92 when the rotating bezel 7 is rotated in the counterclockwise direction A1, that is, the click force, is also reduced.

[0027] The timepiece 1 of the first embodiment has the following advantages. Since the position of the pin 96, which is an abutment member, can be set within the mounting hole 76, which is an elongated hole, the abutment position between the biasing portion 93 of the click spring 90, which is a regulating member, and the pin 96 can be changed, and the magnitude of the biasing force of the biasing portion 93 can be changed. This makes it possible to change the torque required to rotate the rotating bezel 7, and to change the torque feeling during rotation operation, that is, the click force when the engagement portion 92 of the click spring 90 disengages from the regulated receiving portion 64A and engages with the next regulated receiving portion 64A. This makes it possible to eliminate variation in torque during operation of the rotating bezel of the timepiece 1 and adjust it to a constant value, or to adjust the torque according to the user's preference, improving the operability of the rotating bezel 7.

[0028] Since the base portion 71 of the bezel main body 70 is held between the protrusion 63 of the rotating bezel pressing ring 6 and the upper surface 314 of the body 31, the holding structure for the rotating bezel 7 can be simplified and costs can be reduced. Since the click spring 90 that engages with the restriction receiving portion 64A of the circular ring restriction portion 64 is provided on the outer circumferential side of the circular ring restriction portion 64, the circular ring restriction portion 64 and the click spring 90 can be arranged in the radial direction of the watch 1, and the thickness dimension of the watch 1 can be reduced, making it thinner. The protruding portion 63 of the rotating bezel pressing ring 6 has both the function of holding the rotating bezel 7 and the function of restricting the rotation of the rotating bezel 7 by the restricting portion 64A, which simplifies the structure of the rotating bezel pressing ring 6. In addition, since the restricting portion 64A is formed on the protruding portion 63, it can be easily formed by pressing or the like, and the processing cost can also be reduced. Since the rotating bezel retaining ring 6 and the click spring 90 do not need to be disposed inside the case 31, there is no impact on the storage space for the movement 10, and various movements 10 can be used. By engaging the click spring 90 with the restriction receiving portion 64A, the rotating bezel 7 can rotate only in the counterclockwise direction A1, and the rotational position can be maintained every 6°. For this reason, the timepiece 1 of the present disclosure can be applied to a diver's watch in which it is desirable to rotate the rotating bezel 7 only in the counterclockwise direction A1 in order to correctly keep track of the elapsed dive time.

[0029] Since the regulating member is configured by the click spring 90, which is a long, thin lever-shaped part, the click spring 90 can be used in common with watches having different planar sizes. In addition, the biasing portion 93 of the click spring 90 is formed in a long, thin plate shape, and by abutting it against the pin 96 and deforming it, the biasing force with which the engagement portion 92 engages with the regulating portion 64A can be set constant unless the position of the pin 96 is changed. Furthermore, because the click spring 90 engages with the restriction receiving portion 64A from the radial direction of the timepiece 1, the variation in the click force and click sound can be reduced when the rotating bezel 7 is rotated. That is, when the rotating bezel 7 is operated, the user grasps the rotating bezel 7 from above and operates it, so a force is applied that presses the rotating bezel 7 downward. This pressing force varies in the circumferential direction of the rotating bezel 7 depending on how the user holds the rotating bezel 7 and the bias when applying force. For this reason, in the case of a structure that restricts rotation in the vertical direction of the timepiece 1, as in Patent Document 1, the pressing force varies in the circumferential direction, and therefore the click force and the volume of the click sound also vary. In contrast, in the present embodiment, when the restricting portion 64A of the rotating bezel pressing ring 6 and the click spring 90 are arranged in the radial direction of the timepiece 1, the variation in the pressing force from above is not fundamentally affected, so the variation in the click force and the volume of the click sound can be suppressed and stabilized. Furthermore, since the click spring 90 is attached to the rotating bezel 7, the location where the click sound is generated can be changed.

[0030] The protruding portion 63 of the rotating bezel retaining ring 6 is provided with teeth 67 defined by an inclined surface 662, an outer peripheral surface 663, and a restricting surface 65. The area of ​​the teeth 67 can be made larger than in a structure in which the inclined surface 662 is directly connected to the restricting surface 65, such as the sawtooth used in a ratchet mechanism, so that the rotating bezel 7 can be more reliably restricted from moving toward the watch surface, and the rotating bezel 7 can be reliably held by the protruding portion 63 and the case 31.

[0031] The display plate 80 is removably attached to the bezel main body 70, and can hide the rotating bezel retaining ring 6 and the click spring 90, improving the design of the timepiece 1. Furthermore, by removing the display plate 80 from the bezel main body 70, the rotating bezel retaining ring 6 can be exposed and removed, making maintenance work easy to perform. Furthermore, the rotating bezel retaining ring 6 is screwed into the case 31, which also makes it easy to attach and detach it. In particular, the rotating bezel retaining ring 6 is formed with a wrench groove 61, so that the rotating bezel retaining ring 6 can be easily attached and detached from the case 31 by using the same jig that is used when attaching and detaching the screw-type back cover 32.

[0032] [Second embodiment] Next, a timepiece 1B of the second embodiment will be described with reference to Fig. 8 to Fig. 10. The timepiece 1B differs from the timepiece 1 of the first embodiment in that a circular restriction portion 74 is formed on a rotating bezel 7B, and a click spring 90B, which is a restriction member, is attached to a case 31B. Note that in the timepiece 1B, the same components as those in the timepiece 1 of the first embodiment are given the same reference numerals and will not be described. Case 3B of watch 1B differs from case 3 of watch 1 in that a screw hole 36 and a mounting hole 37 are formed in the top surface 314 of case 31B, but the rest of the configuration is the same. Mounting hole 37 is an elongated hole that runs along the circumferential direction of top surface 314. That is, mounting hole 37 is an elongated hole into which pin 96, which is an abutment member, can be installed, and which is formed so that the installation position of pin 96 can be changed at least in the circumferential direction. The rotating bezel pressing ring 6B, like the rotating bezel pressing ring 6 of the first embodiment, includes a ring body 60, a spanner groove 61, a female thread portion 62, and a protruding portion 63. On the other hand, the restricting portion 64A is not formed on the protruding portion 63 of the rotating bezel pressing ring 6B. Therefore, the protruding portion 63 of the rotating bezel pressing ring 6B only has the function of holding the rotating bezel 7B.

[0033] The rotating bezel 7B is composed of a bezel main body 70B and a display plate 80. That is, in the timepiece 1B of the second embodiment, the click spring 90B is attached to the case 31B side and does not rotate with the rotating bezel 7B, so the rotating bezel 7B is composed of the bezel main body 70B excluding the click spring 90B and the display plate 80. The display plate 80 has the same structure as in the first embodiment, so a description thereof will be omitted. The bezel main body 70B includes a base portion 71, an outer periphery 72, and an operation portion 73. The height position of the base portion 71 is provided at the middle position in the up-down direction of the outer periphery 72, and the bottom surface of the base portion 71 is provided at a position higher than the bottom surface of the outer periphery 72. As a result, when the bezel main body 70B is attached to the body 31B with the rotating bezel retaining ring 6B, a space in which the click spring 90B can be disposed is secured between the upper surface 314 of the body 31B and the base portion 71.

[0034] An annular regulating portion 74 is formed along the circumferential direction on the inner peripheral surface of the outer circumferential portion 72 below the base portion 71. The annular regulating portion 74 has a plurality of regulating receiving portions 74A formed continuously in the circumferential direction. In this embodiment, 60 regulating receiving portions 74A are formed in the circumferential direction of the bezel main body 70B. Therefore, the regulating receiving portions 74A are formed at a central angle of 6° in the circumferential direction of the bezel main body 70B. As shown in Fig. 9, the restriction receiving portion 74A has a restriction surface 750 and a guide surface 760. The restriction surface 750 is a surface formed along the diameter direction of the bezel main body 70B, and is provided at a central angle pitch of 6°. Note that, also in Fig. 9, A1 is the counterclockwise direction, and A2 is the clockwise direction. Moreover, the counterclockwise direction A1 is the first direction, and the clockwise direction A2 is the second direction. The guide surface 760 includes an outer circumferential surface 761 that is continuous with the outer circumferential edge of the regulating surface 750, an inclined surface 762 that is continuous obliquely from an end of the outer circumferential surface 761 in the clockwise direction A2 toward the clockwise inner circumference, and an inner circumferential surface 763 that is continuous in the clockwise direction A2 from the inner circumferential end of the inclined surface 762. The edge of the inner circumferential surface 763 in the clockwise direction A2 is continuous with the inner circumferential edge of the next regulating surface 750. As a result, the regulating receiving portion 74A has a tooth portion 770 that is defined by the regulating surface 750, the inner circumferential surface 763, and the inclined surface 762 and protrudes toward the inner circumferential side, and a groove portion 780 that is defined by the regulating surface 750, the outer circumferential surface 761, and the inclined surface 762 and recessed toward the outer circumferential side.

[0035] [Click spring] 8 to 10, the click spring 90B is made of a long and thin plate material, similar to the click spring 90 of the first embodiment, and has a base 91B in which a hole 911 through which a screw 95 is inserted is formed, an engagement portion 92B formed at one end of the base 91B and capable of engaging with the restriction receiving portion 74A of the bezel main body 70B, and a biasing portion 93B extending from the base 91B to a side substantially opposite the engagement portion 92B and having a tip that abuts against the pin 96 which is an abutment member. That is, the click spring 90B of the second embodiment is similar to the click spring 90 of the first embodiment, except that the engagement portion 92B is formed toward the outer periphery side, and the biasing portion 93 is configured to abut against the inner periphery side of the pin 96. For this reason, click spring 90B is rotatably attached to body 31B by screw 95, and engaging portion 92B engages with restriction receiving portion 74A when urging portion 93B abuts against pin 96. Also, by adjusting the position of pin 96 within mounting hole 37, which is an elongated hole, it is possible to adjust the urging force with which engaging portion 92B engages with restriction receiving portion 74A.

[0036] The timepiece 1B can achieve the same effects as the timepiece 1 of the first embodiment, such as allowing the rotating bezel 7B to rotate only in the counterclockwise direction A1. In addition, because the circular restriction portion 74 is formed on the inner peripheral surface of the rotating bezel 7B, there is no need to form a circular restriction portion on the rotating bezel retaining ring 6B, and the processing costs of the rotating bezel retaining ring 6B can be reduced. In addition, because the click spring 90B is attached to the body 31B, the position at which the click spring 90B engages with the restriction receiving portion 74A can be kept constant even when the rotating bezel 7B is rotated, and operability can be stabilized.

[0037] [Third embodiment] Next, a timepiece 1C of the third embodiment will be described with reference to Fig. 11. The timepiece 1C differs from the timepiece 1 of the first embodiment in that a pin 96, which is an abutment member against which the urging portion 93 of the click spring 90 abuts, is attached to a mounting hole 76C, which is a radially elongated hole in the base portion 71 of the bezel main body 70C of the rotatable bezel 7C, but other configurations are the same, so description thereof will be omitted. The mounting hole 76C is an elongated hole in which a pin 96, which is an abutting member, can be installed and which is formed so that the installation position of the pin 96 can be changed at least in the radial direction. In watch 1C, by positioning pin 96 on the outer periphery of mounting hole 76C, the clicking force with which engagement portion 92 engages with regulated portion 64A can be increased, and by positioning pin 96 on the inner periphery of mounting hole 76C, the clicking force with which engagement portion 92 engages with regulated portion 64A can be decreased.

[0038] In timepiece 1C as well, by changing the position of pin 96 within mounting hole 76C, the same effects as in timepiece 1 of the first embodiment can be achieved.

[0039] [Fourth embodiment] Next, a timepiece 1D of the fourth embodiment will be described with reference to Fig. 12. The timepiece 1D differs from the timepiece 1 of the first embodiment in that a pin 96, which is an abutment member against which the biasing portion 93 of the click spring 90 abuts, is attached to one of a plurality of attachment holes 76D formed at intervals in the circumferential direction of the base portion 71 of the bezel main body 70D of the rotatable bezel 7D, but other configurations are the same, so description thereof will be omitted. In watch 1D, as in watch 1, when pin 96 is attached to one of the multiple mounting holes 76D that is farthest from screw 95, the clicking force with which engagement portion 92 engages with regulated portion 64A can be reduced, and when pin 96 is attached to one of the multiple mounting holes 76D that is closer to screw 95, the clicking force with which engagement portion 92 engages with regulated portion 64A can be increased.

[0040] In the timepiece 1D as well, the click force can be changed in stages by changing the position of the pin 96 within the multiple mounting holes 76D, achieving the same effect as the timepiece 1 of the first embodiment.

[0041] [Fifth embodiment] Next, a timepiece 1E of the fifth embodiment will be described with reference to Figures 13A and 13B. The timepiece 1E is attached to a bezel body 70E of a rotating bezel 7E, and is configured with an eccentric pin as a pin 96E, which is an abutment member against which an urging portion 93 of a click spring 90 abuts, and is configured so that the abutment position of the urging portion 93 can be changed by rotating the pin 96E, thereby making it possible to adjust the click force. Since the other configurations are the same, a description thereof will be omitted. The pin 96E is composed of an abutment portion 961 and a rotating shaft 962. The abutment portion 961 is formed in a cylindrical shape, and a screw groove is formed on the upper surface. The central axis of the rotating shaft 962 and the central axis of the abutment portion 961 are provided so as to be shifted in the radial direction of the abutment portion 961. In other words, the abutment portion 961 is provided eccentrically with respect to the rotating shaft 962. Therefore, when the abutment portion 961 is rotated by utilizing the screw groove of the abutment portion 961, the abutment position of the abutment portion 961 with respect to the biasing portion 93 can be changed between the outer peripheral position shown in FIG. 13A and the inner peripheral position shown in FIG. 13B, and thus the clicking force with which the engagement portion 92 engages with the restriction receiving portion 64A can also be changed.

[0042] In timepiece 1E, the clicking force can also be changed by rotating pin 96E to change the contact position between biasing portion 93 and contact portion 961, achieving the same effect as timepiece 1 of the first embodiment. Furthermore, the clicking force can be easily adjusted by simply rotating pin 96E.

[0043] [Variations] The abutment member is not limited to a pin that is press-fitted into the mounting hole. For example, the pin attached to the mounting hole 76, 76C, which is an elongated hole formed in the base part 71, may have a pin part with which the biasing part 93, 93B abuts and a threaded part that protrudes from the mounting hole 76, 76C, and may be configured so that a nut is screwed onto the threaded part and the base part 71 is sandwiched between the pin part and the nut. With this configuration, the position of the pin, which is the abutment member, can be easily changed and adjusted by loosening the nut. In addition, when the pin is press-fitted into the mounting hole, the space in the mounting hole other than the pin may be filled with a spacer member to prevent the pin from moving within the mounting hole. The mounting holes 76 and 37 are elongated holes along the circumferential direction of the bezel main body 70 and the barrel 31B, but may be linear elongated holes. Similarly, the mounting hole 76C is elongated along the radial direction of the bezel main body 70C, but may be elongated holes inclined relative to the radial direction. Furthermore, the mounting hole may be bent midway in the longitudinal direction to be formed into a crank shape or the like, so that the installation position of the pin 96 can be changed in both the circumferential direction and the radial direction. That is, the mounting hole may be an elongated hole in which the pin 96, which is an abutting member, can be installed, and the installation position of the pin 96 can be changed at least in the circumferential direction or the radial direction, and it is sufficient that the position of the pin 96 abutting against the biasing portion 93, 93B can be changed by changing the distance from the screw 95 to the pin 96. Furthermore, the mechanism for changing the position of the abutment member is not limited to the above-described embodiments, and any mechanism that can be incorporated into the timepiece 1 can be used.

[0044] The number of the regulating members is not limited to one, and may be multiple. When multiple regulating members are provided, the timing at which the engagement portion engages with the regulating receiving portion may be the same, or they may be set to engage at different timings. In other words, the number of the regulating receiving portions 64A, 74A formed on the rotating bezel pressing ring 6 or the rotating bezel 7B, and the number of the click springs 90, 90B as the regulating members are not limited to the examples of the above embodiment. For example, assuming that the number of the regulated portions 64A is n and the number of the click springs 90, 90B with the phase shifted when engaging with the regulated portions 64A is m, if n=60 and m=2, the rotating bezel 7 can be regulated every 3° of rotation, and the number of clicks can be set to 120. If n=60 and m=3, the rotating bezel 7 can be regulated every 2° of rotation, and the number of clicks can be set to 180. If n=30 and m=4, the rotating bezel 7 can be regulated every 3° of rotation, and the number of clicks can be set to 120 even if the number of the regulated portions 64A is reduced. Furthermore, the number of the regulated portions 64A, 74A and the number of the click springs 90, 90B with the phase shifted when engaged may be appropriately set, such as n=90, m=2, n=40, m=3, etc. Furthermore, when multiple click springs 90, 90B are provided, it is preferable that the click springs 90, 90B are arranged at approximately equal intervals, but they may also be arranged at different intervals. Furthermore, when multiple click springs 90, 90B are provided, the phases of engagement with the restriction receiving portions 64A, 74A may be matched. For example, three click springs 90, 90B may be arranged at intervals of 120° to simultaneously engage with the restriction receiving portions 64A, 74A. In this case, it is possible to reduce the circumferential variation in the click force when the rotating bezels 7, 7B rotate, and a constant click sound can be generated. Also, multiple sets of click springs 90, 90B may be provided with different phases of engagement with the restriction receiving portions 64A, 74A. For example, when the click springs 90, 90B are provided at four locations at intervals of approximately 90°, two click springs 90, 90B arranged at intervals of 180° may be set to engage with the restriction receiving portions 64A, 74A in the same phase, and these two sets of click springs 90, 90B may be configured to engage with the restriction receiving portions 64A, 74A in different phases. In this case, m=2, and if n=60, the number of clicks is 120.

[0045] In the above embodiment, the restricting portions 64A, 74A and the click springs 90, 90B of the rotating bezel pressing rings 6, 6B are configured to rotate the rotating bezel 7, 7B only in the counterclockwise direction A1, but they may be configured to rotate only in the clockwise direction A2. Also, the restricting portions 64A, 74A may be V-grooves or U-grooves, and the engaging portions 92 of the click springs 90, 90B may be configured to be engageable with the restricting portions 64A, 74A, so that the rotating bezel 7, 7B can be rotated in both the counterclockwise direction A1 and the clockwise direction A2. The restriction receiving portion may be configured so that the teeth are substantially triangular in plan view, like the sawtooth of a ratchet mechanism. The structure for fixing the rotating bezel retaining rings 6, 6B to the body 31, 31B is not limited to the structure in which the rings are fixed by screwing them in as in the above embodiment, but may be any structure that allows the rotating bezel retaining rings 6, 6B to be detachably fixed to the body 31, 31B.

[0046] In the timepiece 1 of the first embodiment, the click spring 90, which is the regulating member, is attached to the bezel main body 70 of the rotating bezel 7, and the circular ring regulating portion 64 is formed in the rotating bezel pressing ring 6, but the circular ring regulating portion may also be formed in the case. For example, the click spring 90 may be rotatably attached to the underside of the base portion 71 of the bezel main body 70B used in the second embodiment with a screw 95, and the circular ring regulating portion may be formed in the case 31B. Also, a circular restriction portion may be formed on the rotating bezel, and a click spring, which is a restriction member, may be attached to the protrusion of the rotating bezel pressing ring.

[0047] The timepiece of the present disclosure is not limited to a diver's watch, but can also be applied to a wristwatch with a rotating bezel. For example, in a watch with a so-called world time function, the names of representative cities in the world's time zones may be displayed around the dial, such as a bezel, and the rotating bezel of the present disclosure may be applied to this display. In addition, in a chronograph watch, a rotating bezel with a circular slide rule for aviation measurement may be applied. Furthermore, in an outdoor watch, a rotating bezel with a simple compass may be applied. The timepiece of the present disclosure is not limited to analog timepieces with hands, but can also be applied to digital timepieces with a liquid crystal panel, etc. In other words, the timepiece of the present disclosure can be applied to various types of timepieces equipped with a rotating bezel.

[0048] [Summary of this disclosure] The timepiece of the present disclosure has a rotating bezel and a holding member that rotatably holds the rotating bezel, the holding member having a case and a rotating bezel pressing ring that is fixed to the case and holds the rotating bezel between the case and the case, and one of the holding member and the rotating bezel is provided with an annular restricting portion having a plurality of restricting receiving portions that are continuous in the circumferential direction, and the other of the holding member and the rotating bezel is provided with a restricting member that engages with the restricting receiving portions to restrict the rotation of the rotating bezel, and an abutting member that abuts against the restricting member. The regulating member comprises a base rotatably attached to either the holding member or the rotating bezel, an engagement portion that engages with the regulating receiving portion, and a biasing portion that extends to the opposite side of the engagement portion across the base and is formed in an elongated shape, and generates a biasing force that biases the engagement portion toward the regulating receiving portion by abutting against the abutment member and elastically deforming, and the abutment member is configured to be able to change the magnitude of the biasing force generated by the biasing portion by changing the position at which it abuts against the biasing portion. According to the timepiece of the present disclosure, the regulating member includes a base portion rotatably attached to the holding member or the rotating bezel, an engaging portion that engages with the regulated portion, and a biasing portion that extends to the opposite side of the engaging portion across the base and is formed in an elongated shape, and generates a biasing force that biases the engaging portion toward the regulated portion by contacting the contact member, and is configured to be able to change the magnitude of the biasing force by changing the contact position of the contact member that contacts the biasing portion. This allows the torque required to rotate the rotating bezel to be changed, and the torque feeling during the rotation operation, that is, the clicking force when the engaging portion of the engaging member disengages from the regulated portion and engages with the next regulated portion, to be changed. This allows the torque to be adjusted to a constant value without variation in torque during operation of the rotating bezel for each timepiece, or to be adjusted according to the user's preference, improving the operability of the rotating bezel. Since the circular regulation part is provided on one of the holding member and the rotating bezel, and the regulation part and the contact member are provided on the other, the circular regulation part and the regulation member can be arranged in the radial direction of the watch. This allows the thickness dimension of the watch to be reduced, making the watch thinner. In addition, since the rotating bezel retaining ring and the regulation member do not need to be arranged inside the case, they do not affect the storage space for the movement, and various movements can be used. In addition, holding the rotating bezel between the rotating bezel pressing ring and the body includes not only a structure in which the rotating bezel is directly held by the rotating bezel pressing ring and the body, but also a structure in which the rotating bezel is held by interposing another substance, such as a sheet, between them.

[0049] In the timepiece of the present disclosure, it is preferable that the circular regulation portion is formed on the outer peripheral surface of the rotating bezel retaining ring, and the regulation member is provided on the rotating bezel. According to the timepiece of the present disclosure, since a circular regulating portion is formed on the outer peripheral surface of the rotating bezel pressing ring, it is not necessary to form a circular regulating portion on the rotating bezel, and the processing cost of the rotating bezel can be reduced. Also, since the regulating member is provided on the rotating bezel, the position of the regulating member changes with the rotation of the rotating bezel, so that the location of the clicking sound generated when the engaging portion of the regulating member disengages from the regulating receiving portion and engages with the next regulating receiving portion can be changed.

[0050] In the timepiece of the present disclosure, it is preferable that the circular regulation portion is formed on the inner surface of the rotating bezel, and the regulation member is provided on the case. According to the timepiece of the present disclosure, since a circular regulating portion is formed on the inner peripheral surface of the rotating bezel, there is no need to form a circular regulating portion on the rotating bezel pressing ring, and the processing cost of the rotating bezel pressing ring can be reduced. Also, since the regulating member is provided on the case, even when the rotating bezel is rotated, the position where the regulating member engages with the regulating receiving portion can be kept constant, and operability can be stabilized.

[0051] In the timepiece of the present disclosure, it is preferable that the other of the retaining member and the rotating bezel has a long hole in which the abutment member can be installed, and that the long hole is formed so that the installation position of the abutment member can be changed at least in the circumferential direction. According to the timepiece of the present disclosure, for example, by forming a long hole along the circumferential direction and changing the installation position of the abutment member within the range of this long hole, the position at which the abutment member abuts the biasing portion can be changed at least in the circumferential direction, thereby making it possible to easily change the biasing force generated by the biasing portion.

[0052] In the timepiece of the present disclosure, it is preferable that the other of the retaining member and the rotating bezel has a long hole in which the abutment member can be installed, and that the long hole is formed so that the installation position of the abutment member can be changed at least in the radial direction. According to the timepiece of the present disclosure, for example, by forming a long hole along the radial direction and changing the installation position of the abutment member within the range of this long hole, the position at which the abutment member abuts the biasing portion can be changed at least in the radial direction, thereby making it possible to easily change the biasing force generated by the biasing portion.

[0053] In the timepiece of the present disclosure, it is preferable that the abutment member is an eccentric pin having a rotation axis and an abutment portion arranged eccentrically with respect to the rotation axis, and that the rotation axis of the eccentric pin is rotatably attached to the other of the retaining member and the rotating bezel. According to the timepiece of the present disclosure, by setting the rotational position of the abutment member which is an eccentric pin, the position at which the abutment member abuts on the biasing portion can be changed, and the biasing force generated by the biasing portion can be easily changed.

[0054] In the timepiece of the present disclosure, it is preferable that the rotating bezel retaining ring has a female threaded portion formed on its inner surface and the case has a male threaded portion formed on its outer surface, and the rotating bezel retaining ring is fixed to the case by screwing the female threaded portion into the male threaded portion. According to the timepiece of the present disclosure, the rotating bezel retaining ring is attached by screwing it into the case, so the rotating bezel retaining ring can be easily attached and detached from the case. Therefore, even if the rotating bezel or the regulating member is damaged, these parts can be easily replaced or repaired, and maintenance work such as cleaning each part can also be easily performed.

[0055] In the timepiece of the present disclosure, when the regulating member is not engaged with the regulating receiving portion, the rotating bezel is rotatable in a first direction, which is one of the clockwise and counterclockwise directions, and in a second direction, which is the other direction, and the regulating receiving portion has a regulating surface that abuts against the engagement portion to regulate rotation of the rotating bezel in the second direction, and a guide surface that is continuously provided from one of the inner peripheral edge or outer peripheral edge of the regulating surface to the other of the outer peripheral edge or inner peripheral edge of the next regulating surface in the first direction, and it is preferable that the engagement portion is guided by the guide surface to move radially against the biasing force as the rotating bezel rotates in the first direction, and when it comes off the guide surface, it moves radially due to the biasing force and abuts against the regulating surface to regulate the rotation of the rotating bezel in the second direction. According to the timepiece of the present disclosure, the regulating portion of the regulating member abuts against the regulating surface of the regulating receiving portion to regulate the rotation of the rotating bezel in the second direction, so the rotating bezel can be regulated to rotate only in the first direction. Therefore, the timepiece of the present disclosure can be applied to a diver's watch in which it is desirable to rotate the rotating bezel in only one direction, counterclockwise, in order to correctly keep track of the elapsed dive time.

[0056] In the timepiece of the present disclosure, it is preferable that the guide surface comprises an inner surface that is continuous with the inner peripheral edge of the regulating surface, an outer peripheral surface that is continuous with the outer peripheral edge of the regulating surface, and an inclined surface connecting the inner peripheral surface and the outer peripheral surface. According to the timepiece of the present disclosure, the protruding portion of the rotating bezel retaining ring is provided with teeth that protrude outward and are bounded by an inclined surface, an outer peripheral surface, and a regulating surface, and the area of ​​these teeth can be made larger than that of sawtooth, so that the rotating bezel can be reliably restricted from moving toward the surface of the watch, and the rotating bezel can be securely held by the protruding portion and the case.
