Description

Technical Field

[0001] This invention relates to watches. Background Technology

[0002] A watch, for example, includes a case, a dial housed within the case, and hands for indicating the time (see, for example, Patent Document 1). In watches, thinness and miniaturization are generally required.

[0003] [Prior Technology Documents] [Patent Literature] [Patent Document 1] Japanese Patent Application Publication No. 2020-191941. Summary of the Invention

[0004] [The problem the invention aims to solve] In watches, the dial, hands, and other components must be housed within the limited space of the watch case to display various functions, resulting in significant spatial constraints. Consequently, it is difficult to maximize the freedom of expression.

[0005] One aspect of this invention aims to provide a watch that enhances the freedom of expression.

[0006] [Solutions for solving the problem] The first aspect of the present invention relates to a watch comprising: a case having a cylindrical case body and a transparent cover member closing an opening of the case body; a dial opposite the cover member, having a display portion for indicating the time; a hand disposed between the cover member and the dial for indicating the time; and a movement for driving the hand. The cover member has a transmissive reflective film that transmits a portion of visible light and reflects another portion of the visible light. The dial has a reflective surface for reflecting the visible light. At least one of the hand and the display portion comprises a light-emitting material.

[0007] Based on this configuration, visual recognition is achieved by reflecting light between the dial and the cover components, through the overlapping of multiple mirror images of the hands, display, etc., along the depth direction. Therefore, despite spatial constraints, a visual effect with a sense of depth can be obtained. Consequently, the freedom of visual expression in the watch can be increased.

[0008] Furthermore, the aforementioned reflection can be represented using external illumination or the light emitted by photoluminescent materials. Therefore, a sufficient visual effect can be achieved without placing a dedicated light source inside the watch. Consequently, it offers advantages in miniaturization and weight reduction compared to cases where a light source is installed.

[0009] The watch according to the second aspect of the present invention may also be the watch according to the first aspect, wherein at least one of the aforementioned hands and the aforementioned display portion includes a fluorescent material, and at least a portion of the aforementioned fluorescent material is used in a different part from the aforementioned phosphorescent material.

[0010] Based on this configuration, the portion using fluorescent material emits light under different conditions than the portion containing phosphorescent material, thus enabling a variety of colors to be displayed depending on the usage environment.

[0011] The watch according to the third aspect of the present invention may also be the watch according to the first or second aspect, wherein the aforementioned pointer has a back side opposite to the aforementioned dial and a display surface as the side opposite to the aforementioned back side, the aforementioned pointer has a cutout formed from the aforementioned display surface to the aforementioned back side, a light-emitting portion including the aforementioned light-emitting material is formed in the aforementioned cutout, and a lining layer covering the aforementioned light-emitting portion is formed on the aforementioned back side when viewed from above.

[0012] Based on this configuration, even if the coating shape of the photoluminescent material is disordered (irregular parts), the lining layer can be used to cover the irregular parts, ensuring a good appearance on the back of the pointer. Because the back of the pointer has a good appearance, aesthetics are ensured.

[0013] The watch according to the fourth aspect of the present invention may also be the watch according to the first or second aspect, wherein the aforementioned pointer has a back surface opposite to the aforementioned dial and a display surface as the side opposite to the aforementioned back surface, the aforementioned pointer has a cutout formed from the aforementioned display surface to the aforementioned back surface, a light-emitting portion including the aforementioned light-emitting material is formed in the aforementioned cutout, and a shielding layer covering the area including the periphery of the aforementioned cutout is formed on the aforementioned back surface.

[0014] Based on this configuration, even if the coating shape of the photoluminescent material is disordered (irregular parts), the irregular parts can be covered by a masking layer, resulting in a good appearance on the back of the pointer. Because the back of the pointer has a good appearance, aesthetics are ensured.

[0015] The watch according to the fifth aspect of the present invention may also be the watch according to any one of the first to fourth aspects, and further have a scale ring including the aforementioned light-emitting material.

[0016] Based on this structure, a visual effect with a sense of depth can be enhanced.

[0017] [The effects of the invention] According to one aspect of the present invention, a watch is provided that can improve the freedom of expression. Attached Figure Description

[0028] Figure 11 This is a cross-sectional view of a modified pointer example. Detailed Implementation

[0029] The following describes the watch according to the embodiments based on the accompanying drawings.

[0030] [watch] Figure 1 This is a perspective view showing a cross-section of the watch 1 according to the embodiment. Figure 2 This is a top view of watch 1. Furthermore, in the following top views, dots have been marked on the luminescent and fluorescent parts for easy observation.

[0031] Combination Figure 1 Assuming the vertical positions of each component are determined, the cover component 11 is positioned above the back cover 13. The positional relationship shown here does not limit the posture of the watch 1 during use. The top-down view is the view taken from a direction parallel to the central axis of the case body 10.

[0032] like Figure 1As shown, watch 1 includes a case 2, a dial 3, hands 4, a movement 5, a scale ring 6, and a watch strap 7 (see reference). Figure 2 ) and rotary operating unit 8 (see reference) Figure 2 ).

[0033] The case 2 includes a case body 10, a cover component 11, a bezel 12, a back cover 13, and two lugs 14. The case body 10 is formed in a cylindrical shape. In this embodiment, the case body 10 is cylindrical. The bezel 12 is located at one open end (the upper open end) of the case body 10. The back cover 13 closes the lower open end of the case body 10. The case 2 houses the dial 3, the hands 4, and the movement 5.

[0034] Lugs 14 protrude from the lower surface of the case body 10. Two lugs 14 are formed at a rotationally symmetrical position of 180° around the case body 10. A watch strap 7 (see reference) is connected to each of the two lugs 14. Figure 2 The watch strap 7 is a band for wearing the watch 1 on the user's arm (wrist). The watch 1 can be worn on the user's arm (wrist) via the watch strap 7.

[0035] The cover component 11 closes the upper opening of the housing body 10. The cover component 11 is plate-shaped. In this embodiment, the cover component 11 is circular plate-shaped. The lower surface 11a of the cover component 11 is the opposing surface opposite to the dial 3. The cover component 11 is transparent. The cover component 11 is formed of transparent materials such as glass or plastic. Transparency means that visible light can be transmitted from one surface to another.

[0036] A transmissive reflective film 15 is formed on the lower surface 11a of the cover member 11. The transmissive reflective film 15 is formed, for example, by a metal such as Ag, Au, or Ti. The transmissive reflective film 15 can be a single-layer film consisting of a single metal layer, or a multi-layer film having multiple metal layers. The transmissive reflective film 15 is formed, for example, by vapor deposition, sputtering, or the like. The transmissive reflective film 15 allows a portion of the irradiated light, which is visible light, to be transmitted from one surface to another, and reflects another portion of the irradiated light. The cover member 11 becomes a semi-reflective mirror by forming the transmissive reflective film 15.

[0037] The visible light transmittance in the thickness direction of the transmissive reflective film 15 can be, for example, 20% or more and 90% or less. Visible light transmittance is the transmittance of light within the wavelength range of visible light (380 nm to 780 nm). Visible light transmittance can be calculated as the average transmittance over the entire wavelength range of visible light. The visible light reflectance in the transmissive reflective film 15 can be, for example, 10% or more and 50% or less. Visible light reflectance can be calculated as the average reflectance over the entire wavelength range of visible light.

[0038] The movement 5 is located between the dial 3 and the case back 13. The movement 5 includes a drive source for driving the rotating axis 16. The rotating axis 16 extends in a direction orthogonal to the dial 3. Rotation operation part 8 (crown) (see reference) Figure 2 This causes the parts inside movement 5 to rotate. Movement 5 can be mechanical or quartz.

[0039] The dial 3 is formed in the shape of a circular plate. A central hole 3c is formed in the center of the dial 3 for the insertion of a rotating shaft 16. The central hole 3c extends through the dial 3 along its thickness direction. The dial 3 has an upper plate 21 (first plate) and a lower plate 22 (second plate).

[0040] The upper plate 21 is, for example, transparent. The upper plate 21 is formed of a transparent material such as glass or plastic. A reflective film 25 is formed on the lower surface 21a of the upper plate 21. The reflective film 25 is, for example, formed of a metal such as Ag, Au, or Ti. The reflective film 25 can be a single-layer film consisting of a single metal layer, or a multi-layer film having multiple metal layers. The reflective surface 25a, which is the upper surface of the reflective film 25, is a mirror. The reflective surface 25a is capable of reflecting visible light. The visible light reflectivity of the reflective surface 25a can be, for example, 70% or more.

[0041] Furthermore, the dial can also be made of a single plate. For example, the dial can be a single metal plate with a mirror-finished surface. When using a mirror-finished metal plate, the surface of the metal plate becomes a reflective surface.

[0042] like Figure 2 As shown, a plurality of first indexing portions 23 and a plurality of second indexing portions 24 are formed on the upper surface 21b (first main surface), which is one side of the upper plate 21. The first indexing portions 23 and the second indexing portions 24 are display portions that indicate the time.

[0043] Multiple first graduations 23 are formed side-by-side at intervals along the circumferential direction of the dial 3, for example, near the outer periphery of the dial 3. The multiple first graduations 23 are formed, for example, at positions from 1 o'clock to 12 o'clock. The first graduations 23 are hour displays. Multiple second graduations 24 are formed side-by-side at intervals between adjacent first graduations 23 along the circumferential direction of the dial 3. The second graduations 24 are minute displays.

[0044] The shapes of the first scale division 23 and the second scale division 24 are not particularly limited. The first scale division 23 and the second scale division 24 may have shapes such as graphics, characters, or symbols. When viewed from above, the first scale division 23 and the second scale division 24 may be stripes (straight lines) along the radial direction of the dial 3, or they may be circular, polygonal (e.g., triangular, rectangular, trapezoidal), numerals (Arabic numerals, Roman numerals, etc.).

[0045] In this embodiment, the first graduations 23 formed at the 12 o'clock and 6 o'clock positions, among the 12 o'clock to 12 o'clock positions, are strips whose width gradually narrows towards the inner side of the dial 3 in a top view. The remaining first graduations 23 are, in a top view, a plurality of triangles (in this embodiment, 3) arranged side by side along the radial direction of the dial 3. The second graduations 24 are lines parallel to the radial direction of the dial 3 in a top view.

[0046] If the first graduation portion 23 and the second graduation portion 24 are different colors from the upper plate 21, visual recognition can be improved. At least one of the first graduation portions 23 includes a photoluminescent material. The photoluminescent material absorbs energy upon receiving light stimulation, converts the absorbed energy into visible light, and emits light after the stimulation stops. By using a photoluminescent material, the first graduation portion 23 is easily visually identifiable even in the dark. The first graduation portion 23 can be formed by applying a photoluminescent material. The first graduation portion 23 can also be formed on the upper surface 21b via a base layer. When the first graduation portion 23 includes a photoluminescent material, the first graduation portion 23 is a photoluminescent portion. The first graduation portion 23 may also include a fluorescent material.

[0047] At least one of the second indexing sections 24 includes a fluorescent material. The fluorescent material emits light by receiving excitation energy. The fluorescent material emits light in the visible light region, for example, by irradiation with ultraviolet light. When the second indexing section 24 includes a fluorescent material, the second indexing section 24 is a fluorescent section. The second indexing section 24 is a different part from the first indexing section 23, which uses a phosphorescent material.

[0048] like Figure 1 As shown, the lower plate 22 overlaps with the lower surface 21a of the upper plate 21. The lower plate 22 is formed of metal, glass, plastic, etc.

[0049] The pointer 4 is positioned between the dial 3 and the cover component 11. The pointer 4 is mounted on the rotating shaft 16.

[0050] Hand 4 has an hour hand 31 (first hand), a minute hand 32 (second hand), and a second hand 33 (third hand). The hour hand 31 rotates in a 12-hour cycle. The minute hand 32 rotates in a 60-minute cycle. The second hand 33 rotates in a 1-minute cycle. Hand 4 indicates the time.

[0051] Figure 3 This is a top view of the display surface 31d of the hour hand 31. Figure 4 This is a top view of the back of the clock hand 31, 31c. Figure 5 This is a cross-sectional view of a portion of the hour hand 31. Figure 5 Show Figure 3 The VV section.

[0052] like Figure 3 and Figure 4 As shown, the hour hand 31, viewed from above, is a long plate-shaped structure whose width gradually narrows from the base end 31b (first end) towards the end end 31a (second end). The hour hand 31 is positioned parallel to the dial 3 (see reference). Figure 1 The back surface 31c (lower surface) is the surface opposite to the dial 3. The display surface 31d (upper surface) is the surface opposite to the back surface 31c.

[0053] like Figure 3 As shown, the hour hand 31 has an insertion through-hole 41, a first opening 42, and a second opening 43. The insertion through-hole 41, the first opening 42, and the second opening 43 are formed by passing the hour hand 31 through the thickness direction. The insertion through-hole 41 is a circular opening. Rotation shaft 16 (see reference) Figure 1 The insertion point 41 is inserted through the insertion point. The clock hand 31 is supported on the rotation axis 16. The orientation from the insertion point 41 toward the base end 31b is the "base end side". The orientation from the insertion point 41 toward the end end 31a is the "end end side".

[0054] The second opening 43 is formed on the end side relative to the insertion through portion 41. When viewed from above, the second opening 43 is trapezoidal in shape, gradually narrowing towards the end. The first opening 42 is formed on the end side relative to the second opening 43. When viewed from above, the first opening 42 is pentagonal in shape, gradually narrowing towards the end. The first opening 42 and the second opening 43 are cuts formed to allow the hour hand 31 to pass through from the display surface 31d to the back surface 31c.

[0055] A light-gathering section 44 is formed in the first opening 42. The light-gathering section 44 includes a light-gathering material. The light-gathering section 44 is formed over the entire area of ​​the first opening 42. The light-gathering section 44 is formed in the form of a film that blocks the first opening 42.

[0056] The display surface 31d of the hour hand 31 can also be surface-processed by grinding, plating, etc. The back surface 31c of the hour hand 31 can also be surface-processed (grinding, plating, etc.) in the same way as the display surface 31d.

[0057] like Figure 4 and Figure 5As shown, a lining layer 45 is formed on the back surface 31c of the hour hand 31. The lining layer 45 is formed in a region wider than the light-emitting portion 44 and includes the light-emitting portion 44 when viewed from above. The base end 45b of the lining layer 45 is located further to the base end than the base end 42b of the first opening 42. The lining layer 45 reaches the two side edges 31e and the end 31a of the hour hand 31. The lining layer 45 covers the entire region of the back surface 31c that is further to the end than the base end 45b. The lining layer 45, for example, exhibits a color with a higher brightness compared to the back surface 31c. The lining layer 45 is white, for example, by including white pigment.

[0058] Figure 6 This is a top view of the display surface 32d of the minute hand 32. Figure 7 This is a top view of the back of the minute hand 32, 32c.

[0059] like Figure 6 and Figure 7 As shown, the minute hand 32, viewed from above, is a long plate-shaped device whose width gradually narrows from the base 32b (first end) towards the end 32a (second end). The minute hand 32 is positioned parallel to the dial 3 (see reference). Figure 1 The back surface 32c (lower surface) is the surface opposite to the dial 3. The display surface 32d (upper surface) is the surface opposite to the back surface 32c.

[0060] like Figure 6 As shown, the minute hand 32 has an insertion through-hole 51, a first opening 52, and a second opening 53. The insertion through-hole 51, the first opening 52, and the second opening 53 are formed by the minute hand 32 passing through it along the thickness direction. The insertion through-hole 51 is a circular opening. Rotation shaft 16 (see reference) Figure 1 The insertion point 51 is inserted through the insertion point. The minute hand 32 is supported on the rotation axis 16. The orientation from the insertion point 51 toward the base end 32b is the "base end side". The orientation from the insertion point 51 toward the end end 32a is the "end end side".

[0061] The second opening 53 is formed on the end side relative to the insertion through portion 51. When viewed from above, the second opening 53 is formed in a trapezoidal shape with its width gradually narrowing towards the end. The first opening 52 is formed on the end side relative to the second opening 53. When viewed from above, the first opening 52 is formed in a pentagonal shape with its width gradually narrowing towards the end. The first opening 52 and the second opening 53 are cuts formed to allow the minute hand 32 to pass through from the display surface 32d to the back surface 32c.

[0062] A light-gathering section 54 is formed in the first opening 52. The light-gathering section 54 includes a light-gathering material. The light-gathering section 54 is formed over the entire area of ​​the first opening 52. The light-gathering section 54 is formed in the form of a film that blocks the first opening 52.

[0063] The display surface 32d of the minute hand 32 can also be surface-processed by grinding, plating, etc. The back surface 32c of the minute hand 32 can also be surface-processed (grinding, plating, etc.) in the same way as the display surface 32d.

[0064] like Figure 7 As shown, a liner layer 55 is formed on the back surface 32c of the minute hand 32. The liner layer 55 is formed in a region wider than the light-emitting portion 54 and including the light-emitting portion 54 when viewed from above. The base end 55b of the liner layer 55 is located further to the base end than the base end 52b of the first opening 52. The liner layer 55 reaches the two side edges 32e and the end 32a of the minute hand 32. The liner layer 55 covers the entire region of the back surface 32c that is further to the end than the base end 55b. The liner layer 55, for example, exhibits a color with a higher brightness compared to the back surface 32c. The liner layer 55 is white, for example, by including white pigment.

[0065] Figure 8 This is a top view of the display surface 33d of the second hand 33. Figure 9 This is a top view of the back of the second hand 33c, which is part of the second hand 33.

[0066] like Figure 8 and Figure 9 As shown, the second hand 33, viewed from above, is a long plate-shaped device whose width gradually narrows from the base 33b (first end) towards the end 33a (second end). The second hand 33 is positioned parallel to the dial 3 (see reference). Figure 1 The back surface 33c (lower surface) is the surface opposite to the dial 3. The display surface 33d (upper surface) is the surface opposite to the back surface 33c.

[0067] like Figure 8 As shown, the second hand 33 has an insertion through-hole 61, a first opening 62, a second opening 63, and a third opening 64. The insertion through-hole 61, the first opening 62, the second opening 63, and the third opening 64 are formed by the second hand 33 passing through it along the thickness direction. The insertion through-hole 61 is a circular opening. Rotation shaft 16 (see reference) Figure 1 The insertion point 61 is inserted through the insertion point. The second hand 33 is supported on the rotation axis 16. The orientation from the insertion point 61 toward the base end 33b is the "base end side". The orientation from the insertion point 61 toward the end end 33a is the "end end side".

[0068] The third opening 64 is formed on the base side relative to the insertion through portion 61. The second opening 63 is formed on the end side relative to the insertion through portion 61. The first opening 62 is formed on the end side relative to the second opening 63. The first opening 62, when viewed from above, has a shape in which the width gradually narrows towards the end side. The first opening 62, the second opening 63, and the third opening 64 are cuts formed to allow the second hand 33 to pass through from the display surface 33d to the back surface 33c.

[0069] A light-gathering portion 65 is formed in the first opening 62. The light-gathering portion 65 includes a light-gathering material. The light-gathering portion 65 is formed over the entire area of ​​the first opening 62. The light-gathering portion 65 is formed in the form of a film that blocks the first opening 62.

[0070] The display surface 33d of the second hand 33 can also be surface-processed by grinding, plating, etc. The back surface 33c of the second hand 33 can also be surface-processed (grinding, plating, etc.) in the same way as the display surface 33d.

[0071] like Figure 9 As shown, a lining layer 66 is formed on the back surface 33c of the second hand 33. The lining layer 66 is formed in a region wider than the light-emitting portion 65 and, when viewed from above, includes the light-emitting portion 65. The base end 66b of the lining layer 66 is located further from the base end 62b of the first opening 62. The lining layer 66 reaches the two side edges 33e of the second hand 33. The lining layer 66, for example, exhibits a color with a higher brightness compared to the back surface 33c. The lining layer 66 is white, for example, by including white pigment.

[0072] When the lining layers 45, 55, and 66 are a bright color (e.g., white), they are less likely to absorb light. Therefore, a portion of the light emitted by the light-emitting units 44, 54, and 65 is reflected by the lining layers 45, 55, and 66 and emitted upwards. Consequently, the amount of light emitted by the light-emitting units 44, 54, and 65 can be increased.

[0073] like Figure 1 As shown, the scale ring 6 is disposed between the dial 3 and the cover component 11. The scale ring 6 is formed along the periphery of the dial 3 when viewed from above. The scale ring 6 is, for example, formed of synthetic resin. The scale ring 6 may include, for example, a photoluminescent material.

[0074] [The effects of the watch involved in the implementation method] In the watch 1 according to this embodiment, a transmissive reflective film 15 is formed on the cover member 11. A reflective film 25 having a reflective surface 25a is formed on the dial 3. A light-glowing material is used for the hands 4 and the first graduation section 23 (hour display section). Light irradiated from the outside is transmitted through the cover member 11 and reflected on the reflective surface 25a of the dial 3, and a portion of the reflected light is reflected by the transmissive reflective film 15 of the cover member 11. Therefore, light is repeatedly reflected between the dial 3 and the cover member 11. Light emitted by the hands 4 (light-glowing section) and the first graduation section 23 is also repeatedly reflected between the dial 3 and the cover member 11. In this way, by reflecting light between the dial 3 and the cover member 11, visual recognition is possible by having multiple mirror images of the hands 4, the first graduation section 23, etc., overlap along the depth direction.

[0075] Since watches are worn on the arm (wrist), their thickness is often a constraint. Therefore, it is difficult to ensure sufficient internal space in a watch. However, in the watch 1 described in this embodiment, despite the space constraints, a visual effect with a sense of depth is achieved. Thus, the freedom of visual expression in the watch is increased.

[0076] In watch 1, the aforementioned mirror image can be represented by external illumination light or the light emitted by a photoluminescent material. Therefore, a sufficient visual effect can be obtained without placing a dedicated light source inside watch 1. Consequently, it is advantageous in terms of miniaturization and weight reduction compared to cases where a light source is installed.

[0077] A fluorescent material is used in the second graduation section 24 (minute display section). At least a portion of the fluorescent material is used in the second graduation section 24, which is a different part from the phosphorescent material. The second graduation section 24 emits light, for example, by exposure to ultraviolet light. The second graduation section 24 emits light under different conditions than the first graduation section 23, which includes the phosphorescent material, thus enabling the watch 1 to display a variety of colors depending on the usage environment.

[0078] like Figure 4 , Figure 7 as well as Figure 9 As shown, lining layers 45, 55, and 66 are formed on the back of the hands 4, covering the light-emitting portions 44, 54, and 65. Therefore, even if the coating shape of the light-emitting material in the light-emitting portions 44, 54, and 65 is disordered (irregular parts), the lining layers 45, 55, and 66 can cover the irregular parts, ensuring a good appearance on the back of the hands 4. In the watch 1, the back of the hands 4 can be visually recognized as a mirror image, but because the back of the hands 4 has a good appearance, aesthetics are ensured.

[0079] The watch 1 has a scale ring 6 made of a light-emitting material, which makes the scale ring 6 illuminated. Therefore, it can enhance the visual effect of depth.

[0080] [Pointer] (Variation Example) Figure 10 This is a perspective view of a partial cross-section of the hour hand 131, which is a variant of the hour hand 31 (pointer 4). Figure 11 This is a cross-sectional view of the hour hand at 131. (Regarding...) Figures 3 to 5 The common components of the clock hand 31 (pointer 4) shown are labeled with the same reference numerals and the description is omitted.

[0081] like Figure 10 and Figure 11 As shown, the hour hand 131 has a display surface 131d and a back surface 131c. The back surface 131c is opposite to the dial 3. The display surface 131d is the surface opposite to the back surface 131c. A light-emitting portion 44 is formed in the first opening 42.

[0082] A shielding layer 145 is formed on the back side 131c of the hour hand 131. The base end 145b of the shielding layer 145 is located further from the base end 42b of the first opening 42. The shielding layer 145 covers the region including the inner periphery 42c (periphery of the cut) of the first opening 42 when viewed from above. The shielding layer 145 reaches the two side edges 131e and the end of the hour hand 131. The shielding layer 145 is formed in the annular region excluding the first opening 42 from the entire region further from the base end 145b to the end side. The shielding layer 145 is formed in the region from the inner periphery 42c of the first opening 42 to the side edge 131e (outer periphery).

[0083] The masking layer 145 can be the same color as the back surface 131c. For example, if the back surface 131c of the clock hand 131 is black, the masking layer 145 can be black. The masking layer 145 can also be a color with a lower brightness than the back surface 131c.

[0084] A shielding layer 145 is formed on the hour hand 131. Therefore, even if the coating shape of the light-emitting material in the light-emitting part 44 is disordered (irregular part), the shielding layer 145 can cover the irregular part, so that the back of the hand 4 has a good appearance. In the watch 1, the back of the hand 4 can be visually recognized as a mirror, but because the back of the hand 4 has a good appearance, it is possible to ensure aesthetics.

[0085] The present invention is not limited to the embodiments described above with reference to the accompanying drawings, and various modifications can be considered within its technical scope.

[0086] exist Figure 1 The watch 1 shown uses a phosphorescent material in the hands 4 and the first graduation section 23, but at least one of the hands 4 and the first graduation section 23 may also use a phosphorescent material. For example, it is also possible to use a phosphorescent material in only one of the hands 4 and the first graduation section 23. In addition, when phosphorescent materials are used in the hands, it is sufficient that at least one of the multiple hands (e.g., the hour hand, the minute hand, and the second hand) uses a phosphorescent material.

[0087] exist Figure 1 The watch 1 shown uses a fluorescent material in the second graduation section 24, but at least one of the hands 4 and the second graduation section 24 may also use a fluorescent material. For example, it is also possible to use a fluorescent material only in one of the hands 4 and the second graduation section 24. In addition, if a fluorescent material is used in the hands, it is sufficient that at least one of the multiple hands uses a fluorescent material.

[0088] exist Figure 1In the watch 1 shown, a transmissive reflective film 15 is formed on the lower surface 11a of the cover member 11, but the transmissive reflective film 15 is not limited to the lower surface 11a of the cover member 11, and may also be formed inside the cover member 11. Figure 1 The watch 1 shown has a reflective film 25 formed on the lower surface 21a of the upper plate 21, but the reflective film 25 is not limited to the lower surface 21a of the upper plate 21, and can also be formed inside the upper plate 21.

[0089] Figure 4 The lining layer 45 shown is formed reaching the side edge 31e and the end 31a, but the area where the lining layer is formed is not particularly limited. For example, the lining layer may also be formed in the area that includes the phosphorescent part when viewed from above and does not reach the side edge and the end.

[0090] exist Figure 10 As shown in the clock hand 131, the shielding layer 145 is formed on the back side 131c in an annular region excluding the first opening 42 from the entire region further to the end side than the base end 145b, but the shielding layer may also be formed in the entire region further to the end side than the base end 145b.
