[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0042] In this application, unless otherwise clearly stipulated and defined, terms such as "installed", "connected", "joined", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components.

[0044] As Figure 1 shown, in the prior art, when assembling the watch head 100, the bezel 12 and the bottom case 13 are usually respectively assembled and connected to the corresponding sides of the watch case 11, that is, after one of the bezel 12 and the bottom case 13 is assembled to the watch case 11, the other component is then assembled onto the watch case 11. Thus, it takes more assembly time and affects the production efficiency of the watch head 100.

[0045] Embodiment 1

[0046] An embodiment provides a watch head 100 that can achieve rapid assembly, improve the assembly efficiency of the watch head 100, and further improve the production efficiency.

[0047] As Figure 2 and Figure 3 shown, the watch head 100 includes a housing assembly 10 and a locking assembly 20. Among them, the housing assembly 10 may include a watch case 11, a bezel 12, and a bottom case 13, and the locking assembly 20 can be used for locking and fixing between the watch case 11, the bezel 12, and the bottom case 13, that is, fixing and assembling the bezel 12 and the bottom case 13 to the corresponding sides of the watch case 11.

[0048] In some embodiments, the bezel 12 is fitted and assembled on one side of the watch case 11, and the back case 13 is fitted and assembled on the side of the watch case 11 away from the bezel 12. The watch case 11, the bezel 12 and the back case 13 enclose a receiving cavity 16, and the receiving cavity 16 can be used to install the internal structures of the watch head 100, such as the movement 40 and the dial 60, etc. In the embodiments, the watch case 11, the bezel 12 and the back case 13 can all be generally presented as circular rings.

[0049] The housing assembly 10 is further provided with a through-hole group 15 penetrating through the bezel 12, the watch case 11 and the back case 13. The locking assembly 20 is inserted through the through-hole group 15 to assemble the bezel 12 and the back case 13 on the corresponding sides of the watch case 11 at the same time.

[0050] Specifically, the locking assembly 20 may include a first locking member 21 and a second locking member 22 connected to each other. Wherein, one end of the first locking member 21 away from the second locking member 22 is limited to the side of the bezel 12 away from the watch case 11, and one end of the second locking member 22 away from the first locking member 21 is limited to the side of the back case 13 away from the watch case 11.

[0051] In some embodiments, multiple groups of the locking assemblies 20 may be provided. Exemplarily, the number of the locking assemblies 20 is set to two groups, three groups, four groups, six groups, eight groups, etc. The multiple groups of locking assemblies 20 can be evenly distributed at intervals around the axis 101 of the watch head 100. Correspondingly, the same number of through-hole groups 15 can also be provided on the housing assembly 10, and the locking assemblies 20 and the through-hole groups 15 are in one-to-one correspondence. Thereby, the stable assembly of all directions of the watch case 11, the bezel 12 and the back case 13 is ensured, and the bezel 12 and the back case 13 are prevented from randomly shaking relative to the watch case 11.

[0052] During assembly, the bezel 12, the watch case 11 and the back case 13 can be stacked in sequence first. Subsequently, the first locking member 21 can be inserted from one end of the through-hole group 15 close to the bezel 12, and one end of the first locking member 21 away from the second locking member 22 is limited to the side of the bezel 12 away from the watch case 11. The second locking member 22 is inserted from one end of the through-hole group 15 close to the back case 13, and one end of the second locking member 22 away from the first locking member 21 is limited to the side of the back case 13 away from the watch case 11. At the same time, the first locking member 21 and the second locking member 22 are connected.

[0053] Thereby, the tight assembly between the watch case 11, the bezel 12 and the back case 13 can be completed, that is, the assembly of the three components can be completed through one assembly process. Compared with the assembly method in the prior art, the assembly efficiency of the watch head 100 can be significantly improved. Correspondingly, the production efficiency of the watch can also be improved.

[0054] Embodiment Two

[0055] In the embodiments, a watch head 100 is provided. It can be understood that these embodiments can be further improvements made on the basis of Embodiment 1.

[0056] As Figure 2 and Figure 3 shown, in some embodiments, the watch case 11 can be a transparent watch case, and the bezel 12 can be a transparent bezel 12. Correspondingly, from the circumferential side of the watch head 100, the internal structure of the watch head 100 can be seen, making the watch head 100 present a perspective structure and enriching the appearance effect of the watch head 100.

[0057] In the prior art, a housing assembly 10 made of a metal texture is usually adopted, and users can basically not see the internal structure of the watch head 100. In this application, the watch case 11 and the bezel 12 are set to be transparent, which can achieve a perspective structure to provide different visual effects and enrich the appearance effect of the watch head 100.

[0058] In some specific embodiments, both the watch case 11 and the bezel 12 can be made of acrylic (polymethylmethacrylate, PMMA). While having a perspective effect, they can also have relatively high hardness, that is, it can ensure that the watch case 11 and the bezel 12 have relatively high structural strength.

[0059] Of course, in some other embodiments, the watch case 11 and the bezel 12 are not excluded from being made of materials such as glass and tempered glass.

[0060] In some embodiments, the watch case 11 and the bezel 12 can also be made of transparent materials with colors, such as blue, orange, gray, red, etc.

[0061] Combined with Figures 5 to 7 again, the through-hole group 15 includes a through hole 151, a stepped hole 152, and a stepped hole 153. The through hole 151 is provided on the watch case 11, the stepped hole 152 is provided on the bezel 12, and the stepped hole 153 is provided on the bottom case 13. Correspondingly, the stepped hole 152 and the stepped hole 153 are respectively arranged at both ends of the through hole 151. The through hole 151, the stepped hole 152, and the stepped hole 153 are coaxial.

[0062] In some embodiments, the stepped hole 152 can include an abutting surface 1522. The first abutting arm 1522 is arranged away from the through hole 151, and one end of the first locking member 21 away from the second locking member 22 can be limited and abutted against the abutting surface 1522. The stepped hole 153 includes an abutting wall 1531. The abutting wall 1531 can be arranged away from the through hole 151, and one end of the second locking member 22 away from the first locking member 21 is limited and abutted against the abutting wall 1531.

[0063] Combined with Figure 8 and Figure 9, in some embodiments, the first locking member 21 may include a first connecting portion 211 and a limiting flange 212. The first connecting portion 211 may be a rod-shaped structure, and one end of the first connecting portion 211 may be used to connect the second locking member 22. The limiting flange 212 is disposed at one end of the first connecting portion 211 away from the second locking member 22, and the outer edge of the limiting flange 212 protrudes from the circumferential side wall of the first connecting portion 211. Correspondingly, the connection portion between the first connecting portion 211 and the limiting flange 212 may also present a stepped structure. During assembly, one side wall of the limiting flange 212 close to the first connecting portion 211 may abut against the abutting surface 1522.

[0064] The second locking member 22 may include a second connecting portion 221 and a first limiting boss 222. One end of the second connecting portion 221 may be used to connect the first locking member 21, that is, to connect the first connecting portion 211. The first limiting boss 222 is connected to one end of the second connecting portion 221 away from the first locking member 21. The second connecting portion 221 may also be a rod-shaped structure, and the outer edge of the first limiting boss 222 protrudes from the circumferential side wall of the second connecting portion 221. Correspondingly, the connection portion between the second connecting portion 221 and the first limiting boss 222 may also present a stepped structure. During assembly, one end of the first limiting boss 222 close to the second connecting portion 221 may abut against the abutting wall 1531.

[0065] In some embodiments, the first connecting portion 211 and the second connecting portion 221 are detachably connected. Specifically, a threaded hole 2111 is provided at one end of the first connecting portion 211 close to the second locking member 22. Correspondingly, an external thread that mates with the threaded hole 2111 is provided at one end of the second connecting portion 221 close to the first locking member 21, that is, the first connecting portion 211 and the second connecting portion 221 are connected by a threaded fit. It can be understood that the threaded fit length between the first connecting portion 211 and the second connecting portion 221 can satisfy such that the limiting flange 212 abuts against the abutting surface 1522 and the first limiting boss 222 abuts against the abutting wall 1531. Thus, the tight assembly between the watch case 11, the bezel 12, and the back case 13 can also be ensured.

[0066] In some other embodiments, the first connecting portion 211 and the second connecting portion 221 may also be detachably or non-detachably connected by means of snap connection, interference fit, bonding, etc., that is, the connection between the first locking member 21 and the second locking member 22 is achieved.

[0067] In some specific embodiments, the first connecting portion 211 may be cylindrical, and correspondingly, the through hole 151 may also be a cylindrical through hole. The diameter of the first connecting portion 211 may be equal to the diameter of the through hole 151. Thus, the limitation between the watch case 11 and the locking assembly 20 can also be achieved.

[0068] The limiting flange 212 can be a non-circular limiting flange 212. Correspondingly, a limiting hole 1521 is provided at one end of the stepped hole 152 away from the through hole 151. The limiting hole 1521 is located on the side of the abutting surface 1522 away from the through hole 151, and the shape of the limiting hole 1521 matches the shape of the limiting flange 212.

[0069] In some specific embodiments, in a direction perpendicular to the axis of the locking assembly 20, the cross-section of the limiting flange 212 can be hexagonal. Correspondingly, the limiting hole 1521 can also be hexagonal, and the size of the limiting hole 1521 is equal to the size of the limiting flange 212. The circumferential side wall of the limiting flange 212 can be attached to the inner wall of the limiting hole 1521. Thus, the rotation of the limiting flange 212 relative to the limiting hole 1521 can be restricted. Correspondingly, the random rotation of the first locking member 21 relative to the housing assembly 10 can also be restricted, improving the assembly efficiency of the first locking member 21 and the second locking member 22.

[0070] In other embodiments, the cross-section of the limiting flange 212 can also be set in shapes such as oval, quadrilateral, pentagon, irregular polygon, etc., and the shape of the limiting hole 1521 can be adaptively adjusted according to the shape of the limiting flange 212.

[0071] In the embodiment, the cross-section of the first limiting boss 222 can be circular. Correspondingly, the corresponding end of the stepped hole 153 can also be set as a circular hole, so that the first limiting boss 222 can rotate smoothly relative to the stepped hole 153, and further facilitate the threaded mating connection between the first locking member 21 and the second locking member 22. It can be understood that the diameter size of the first limiting boss 222 is equal to the diameter size of the corresponding end of the stepped hole 153 to prevent random shaking between the second locking member 22 and the bottom case 13. Thus, in a direction perpendicular to the axis 101, the relative fixation among the watch case 11, the bezel 12, the bottom case 13, and the locking assembly 20 can be achieved.

[0072] Further, in some embodiments, a positioning groove 2121 is provided at one end of the limiting flange 212 away from the first connecting portion 211. An assembly groove 2221 is provided at one end of the first limiting boss 222 away from the second connecting portion 221. The settings of the positioning groove 2121 and the assembly groove 2221 can facilitate the positioning connection between the locking assembly 20 and the assembly tool, such as a screwdriver, to facilitate the connection between the first locking member 21 and the second locking member 22 and improve the assembly efficiency. At the same time, by means of the assembly tool acting on the first locking member 21, a large acting force of the first locking member 21 on the side wall of the limiting hole 1521 can be avoided, thereby avoiding problems such as scratches and cracks on the bezel 12.

[0073] During assembly, the bezel 12 and the bottom case 13 can be respectively placed on the corresponding sides of the watch case 11 and locked and fixed by the locking assembly 20. Among them, there is no need to tap threads on the watch case 11 and the bezel 12, which can avoid the problem of cracking and damage of the watch case 11 and the bezel 12 during thread tapping, and can also avoid the problem of slipping threads, ensuring the stable assembly among the watch case 11, the bezel 12 and the bottom case 13. In addition, by locking and fixing the watch case 11, the bezel 12 and the bottom case 13 by the locking assembly 20, there is no need to set interference fit between the watch case 11 and the bezel 12, and between the watch case 11 and the bottom case 13, thus effectively avoiding the problem of cracking of the watch case 11 and the bezel 12. Therefore, the success rate of assembling the watch head 100 can be significantly improved, the loss can be reduced, and the production cost can be reduced.

[0074] As Figure 10 shown, in some embodiments, a plurality of first cut surfaces 11a and a plurality of second cut surfaces 11b are circumferentially arranged on one side of the watch case 11 away from the bottom case 13. The first cut surfaces 11a are arranged close to the axis 101 of the watch head 100, and the second cut surfaces 11b are connected to the side of the first cut surfaces 11a away from the axis 101. The second cut surfaces 11b and the first cut surfaces 11a are connected by a cross section 11c to form a stepped structure, showing a gradual transition. Thus, the watch case 11 can present the beauty of the combination of geometry and lines, and can also present a more three-dimensional visual effect. During processing, first, the overall shape of the watch case 11 is formed by injection molding, and then the first cut surfaces 11a, the second cut surfaces 11b and the cross section 11c are formed on the surface of the watch case 11 by computer numerical control (CNC) machining, avoiding the problem of cracking. In some embodiments, both the first cut surfaces 11a and the second cut surfaces 11b can be inclined surfaces, and are inclined gradually from the end close to the axis 101 towards the direction close to the bottom case 13. The height of the cross section 11c can be set to 0.1 mm to 0.2 mm.

[0075] In some embodiments, the housing assembly 10 further includes a bottom plate 14, and the bottom plate 14 is embedded in the bottom case 13. The bottom plate 14 can also close the opening on the side of the accommodation cavity 16 away from the bezel 12. Specifically, the bottom case 13 can be a hollow structure, and a circular embedding hole for installing the bottom plate 14 can be arranged in the middle thereof. The embedding hole is coaxial with the axis 101, that is, the bottom case 13 can be generally presented as an annular shape. Correspondingly, the bottom plate 14 can also be a circular plate structure, and the bottom plate 14 is fixedly embedded in the embedding hole.

[0076] In some embodiments, the bottom plate 14 may be made of glass, and the bottom shell 13 may be made of stainless steel, and the user may see the internal structure of the meter head 100 through the bottom plate 14. A third sealing ring 83 is provided between the circumferential side wall of the bottom plate 14 and the bottom shell 13, which can achieve waterproof and dustproof effects on one hand, and can also fix the bottom plate 14 on the bottom shell 13 on the other hand, and provide corresponding protection for the bottom plate 14 to prevent the bottom plate 14 from breaking.

[0077] In other embodiments, the bottom plate 14 may also be made of acrylic, tempered glass, etc. The bottom shell 13 may also be made of aluminum alloy, copper alloy, etc.

[0078] Combination Figure 3 and Figure 4 As shown, in some embodiments, the bottom shell 13 is close to the watch case 11, and a fifth sealing ring 85 is further provided. The fifth sealing ring 85 is provided between the bottom shell 13 and the watch case 11, and is used to seal the assembly gap between the bottom shell 13 and the watch case 11, that is, to block the communication between the outside of the housing assembly 10 and the internal accommodating cavity 16, thereby achieving dustproof and waterproof effects.

[0079] Combined with Figure 7 , the bottom shell 13 is close to the watch case 11, and a boss 131 is arranged around it. The boss 131 is annular and coaxial with the bottom shell 13. It can be understood that after assembly, the boss 131 is arranged on the side of the watch case 11 close to the accommodating cavity 16. A limiting groove 132 is arranged on the side of the boss 131 away from the center of the bottom shell 13, and the fifth sealing ring 85 can be partially accommodated in the limiting groove 132. The side of the fifth sealing ring 85 away from the center of the bottom shell 13 protrudes from the limiting groove 132, so that the fifth sealing ring 85 can be contacted and connected with the watch case 11. Among them, the limiting groove 132 can limit the fifth sealing ring 85. During assembly, the fifth sealing ring 85 can be pre-assembled in the limiting groove 132 first, and then the bottom shell 13 can be assembled on the corresponding side of the watch case 11. Among them, one end of the fifth sealing ring 85 protruding from the limiting groove 132 can abut on the watch case 11.

[0080] Specifically, in the direction parallel to the axis 101, the fifth sealing ring 85 can be supported between the watch case 11 and the bottom case 13. On the one hand, the fifth sealing ring 85 plays a buffering role between the bottom case 13 and the watch case 11, that is, it can absorb part of the extrusion force of the locking assembly 20 on the housing assembly 10, and prevent the watch case 11 and the bezel 12 from being broken and damaged due to excessive force. On the other hand, the fifth sealing ring 85 can also seal the connection between the bottom case 13 and the watch case 11. In the direction perpendicular to the axis 101, it can be understood that in the radial direction of the watch head 100, the fifth sealing ring 85 can also abut between the watch case 11 and the bottom case 13 to play a sealing and buffering role.

[0081] Further, such as Figure 3As shown, the watch head 100 further includes a watch cover 50. The watch cover 50 is disposed on the side of the accommodation cavity 16 away from the bottom plate 14. The watch cover 50 can be used to close the opening on the side of the accommodation cavity 16 away from the bottom plate 14, thereby making the accommodation cavity 16 a closed space. In some embodiments, the watch cover 50 can be a colorless transparent glass plate.

[0082] In an embodiment, the watch cover 50 is fixedly connected to the side of the watch case 11 close to the bezel 12. Specifically, the watch cover 50 can be fixedly embedded in the watch case 11. A fourth sealing ring 84 is disposed between the watch cover 50 and the inner side wall of the watch case 11. It can be understood that the fourth sealing ring 84 can be compressed between the watch cover 50 and the watch case 11. Among them, the fourth sealing ring 84 can seal the connection between the watch cover 50 and the watch case 11 to achieve the effects of dust prevention and waterproofing. On the other hand, the fourth sealing ring 84 can also play a buffering role between the watch cover 50 and the watch case 11, avoiding damage to the watch cover 50 and the watch case 11 caused by direct contact and extrusion between the watch cover 50 and the watch case 11. In the embodiment, at the end of the watch case 11 away from the bottom case 13, there is also a support platform 113 for supporting the watch cover 50, which can also play a corresponding limiting role for the watch cover 50.

[0083] In some embodiments, the surface of the watch cover 50 away from the bottom case 13 can be flush or nearly flush with the surface of the bezel 12 away from the watch case 11. The bezel 12 surrounds the watch cover 50, and there can be a gap between the bezel 12 and the watch cover 50 to avoid damage caused by mutual extrusion and collision between the bezel 12 and the watch cover 50.

[0084] In the embodiment, the watch head 100 further includes a movement 40 and a dial 60. Among them, the dial 60 is fixedly installed in the accommodation cavity 16 and divides the accommodation cavity 16 into two sub-cavities. One sub-cavity is located on the side of the dial 60 close to the bottom case 13, and the other sub-cavity is located on the side of the dial 60 close to the watch cover 50.

[0085] The movement 40 is fixedly installed in a sub-cavity close to the bottom case 13. Specifically, the watch head 100 further includes a fixing cover 70. The fixing cover 70 is fixedly disposed in the accommodation cavity 16 and is close to the bottom case 13. The movement 40 can be fixedly installed in the accommodation cavity 16 through the fixing cover 70. In some embodiments, the fixing cover 70 can be made of copper.

[0086] In some embodiments, the fixing cover 70 can be located on the side of the dial 60 close to the bottom case 13, and the fixing cover 70 can also play a supporting role for the dial 60. Correspondingly, the fixing cover 70 can cooperate with the flange on the inner wall of the watch case 11 to limit the fixing cover 70, that is, the side of the dial 60 away from the fixing cover 70 can abut against the flange on the inner wall of the watch case 11. Thus, the dial 60 is fixedly installed in the accommodation cavity 16. It can be understood that the side of the fixing cover 70 away from the dial 60 can abut against the bottom case 13.

[0087] On the side of the dial 60 away from the movement 40, there are also provided hour and minute hands 61 and time markings (not shown in the figure). The hour and minute hands 61 can cooperate with the time markings to display the corresponding time.

[0088] Furthermore, the watch head 100 further includes a crown 30. The crown 30 can be connected to the movement 40 through a crown core (not shown in the figure). The crown 30 can be used to adjust and control the operation of the movement 40, and can be used to adjust the time of the watch head 100 and wind the mainspring in the movement 40 to generate the energy for the watch head 100 to run. It can be understood that the movement 40 can be a mechanical movement.

[0089] Of course, in some other embodiments, the movement 40 can also be an electronic movement.

[0090] Combined with Figures 3 to 5 As shown, in some embodiments, a crown tube 111 extends from one side of the watch case 11 in a direction away from the accommodation cavity 16. The crown tube 111 and the watch case 11 are of an integral structure. The crown 30 is installed at the position of the crown tube 111.

[0091] Combined with Figure 11 , the crown 30 includes a crown head 31 and a first connecting rod 32. The crown head 31 is connected to one end of the first connecting rod 32. The crown tube 111 is internally provided with a through hole 1111 communicating the accommodation cavity 16 with the external environment. The end of the first connecting rod 32 away from the crown head 31 passes through the through hole 1111 and is connected to the end of the crown core away from the movement 40. The crown head 31 is limited to the outside of the watch case 11, that is, on the side of the watch case 11 away from the accommodation cavity 16. A mating groove 314 is further provided on the side of the crown head 31 close to the watch case 11. The mating groove 314 is arranged around the first connecting rod 32. During assembly, the end of the crown tube 111 away from the accommodation cavity 16 is inserted into the mating groove 314. In some embodiments, the crown 30 can be made of stainless steel.

[0092] In some embodiments, the crown tube 111 includes an inner surface 1112 and an outer surface 1113. Among them, the inner surface 1112 can be understood as the inner wall of the through hole 1111. The outer surface 1113 is located on the side of the crown tube 111 away from the inner surface 1112, and the outer surface 1113 is located outside the housing assembly 10.

[0093] At least one first sealing ring 81 is provided between the first connecting rod 32 and the inner surface 1112. At least one second sealing ring 82 is provided between the crown head 31 and the outer surface 1113. It can be understood that at least one second sealing ring 82 is provided between the side wall of the mating groove 314 away from the first connecting rod 32 and the outer surface 1113. Among them, the first sealing ring 81 and the second sealing ring 82 cooperate to seal the assembly gap between the crown 30 and the crown tube 111 to achieve the effects of dust prevention and waterproofing.

[0094] In some embodiments, two first sealing rings 81 are provided between the first connecting rod 32 and the inner surface 1112, and two second sealing rings 82 are provided between the chuck 31 and the outer surface 1113 to improve the waterproof and dustproof effects.

[0095] Of course, in other embodiments, the number of the first sealing rings 81 can also be set to one, three, four, etc. The number of the second sealing rings 82 can also be set to one, three, four, etc.

[0096] In some embodiments, a sink for accommodating the second sealing ring 82 is provided at one end of the chuck 31 close to the watch case 11. The sink extends from the inner wall of the mating groove 314 in a direction away from the first connecting rod 32 and is provided at the opening end of the sink close to the mating groove 314. A limiting block 311 is fixedly provided at one end of the chuck 31 close to the watch case 11. The limiting block 311 corresponds to the sink, and the limiting block 311 is used to limit the second sealing ring 82 in the sink. During assembly, the second sealing ring 82 can also be pre-installed in the sink, and then the chuck 30 is assembled at the position of the barrel 111.

[0097] In some embodiments, one end of the chuck 31 close to the watch case 11 is provided as a flat surface 313, so that the chuck 31 is in surface contact with the watch case 11, thereby avoiding scratching or damaging the watch case 11 by the chuck 31.

[0098] In some embodiments, a gap is left between the barrel 111 and the bottom of the mating groove 314, that is, the length of the barrel 111 is less than the depth of the mating groove 314. Wherein, the bottom of the mating groove 314 is the side wall of the mating groove 314 away from the watch case 11. During assembly, it is avoided that the chuck 30 impacts the barrel 111 and causes the barrel 111 to break.

[0099] In the prior art, it is usually necessary to provide an additional barrel 111 structure and assemble the barrel 111 at the corresponding position of the watch case 11 by an interference fit method. In this application, the barrel 111 and the watch case 11 are provided as an integral body, which can avoid damaging the watch case 11 when pressing the barrel 111 and the watch case 11, that is, the watch case 11 and the barrel 111 can be protected. On the other hand, the assembly efficiency can also be improved.

[0100] As Figure 11 shown, a plurality of convex ribs 312 are further provided on the circumferential side wall of the chuck 31. Grooves are formed between adjacent two convex ribs 312, and the extending direction of the convex ribs 312 is parallel to the axis of the first connecting rod 32. Thus, an anti-slip pattern structure is formed on the circumferential side wall of the chuck 31 to facilitate the user to rotate the chuck 31. In some embodiments, the side of the convex rib 312 away from the groove is a flat surface structure, so as to avoid scratching the user by the convex rib 312.

[0101] In some embodiments, the watch head 100 further includes a decorative piece 90 which is disposed around the circumferential side wall of the bushing 31. The decorative piece 90 can be used to decorate the watch head 100. At the same time, it can also make the bushing 30 more prominent, facilitating the user to find the bushing 30 for relevant operations.

[0102] In some embodiments, two symmetrical lugs 112 are further provided on the watch case 11, and the lugs 112 can be used to connect the watch band 200.

[0103] In summary, the present application provides a watch head 100, which can achieve a perspective effect to present different visual effects and enrich the appearance form of the watch head 100. At the same time, it can significantly improve the assembly efficiency, thereby improving the production efficiency of the watch.
