Description

Technical Field

[0001] This invention relates to the field of mechanical watches, and more particularly to a modular moon phase display mechanism. Background Technology

[0002] Moon phase display is a common feature on watches. By viewing the moon phase through a window on the watch dial, one can observe the waxing and waning of the moon, a feature that is very popular with consumers.

[0003] Chinese utility model patent CN208805684U discloses a moon phase display mechanism for a watch. The moon phase display structure disclosed in this patent is relatively complex and needs to be designed synchronously with the movement. It cannot be transferred as a modular additional mechanism to various different movements. Secondly, the patent describes that the moon phase wheel is turned once every 24 hours and completes its rotation in 30 days, while the cycle of the moon phase is approximately 29.53 days, so its moon phase display accuracy deviates slightly from reality.

[0004] Therefore, there is an urgent need to design a modular moon phase display mechanism to improve the versatility of the moon phase display mechanism and reduce the design difficulty of the watch. Summary of the Invention

[0005] This invention provides a modular moon phase display mechanism, which features good manufacturability, simple assembly, and suitability for mass production. The specific technical solution is as follows:

[0006] A modular moon phase display mechanism includes a base plate, on which a connecting unit is disposed. The connecting unit is connected to a driving unit, and the driving unit is connected to a display unit. The connecting unit, driving unit, and display unit are all disposed on the base plate to form an independent modular mechanism. The connecting unit can be connected to a watch movement, and the movement of the watch movement can be transmitted to the driving unit through the connecting unit, so that the driving unit drives the display unit to rotate to display different moon phase changes.

[0007] Furthermore, the connecting unit includes a double hour wheel, which is coaxially and fixedly connected to the hour wheel of the watch movement. The double hour wheel is connected to the drive unit to transmit the movement of the watch movement to the drive unit. The drive unit includes a date changing wheel, which meshes with the double hour wheel of the connecting unit. The date changing wheel is coaxially connected to the date changing head, which corresponds to the moon phase wheel. The moon phase wheel is connected to the display unit. The date changing wheel can rotate the moon phase wheel by changing the date changing head, thereby changing the moon phase displayed by the display unit.

[0008] Furthermore, the display unit includes a moon phase disk and a blocking disk. The moon phase disk has a moon pattern, and the blocking disk is positioned above the moon phase disk to block the moon pattern. The moon phase disk is coaxially and fixedly connected to the moon phase wheel. The date wheel can be rotated by the date wheel, which in turn drives the moon phase disk to rotate, thereby changing the area blocked by the blocking disk and thus changing the moon phase displayed by the display unit.

[0009] Furthermore, the number of days in a lunar cycle is: (number of teeth on the lunar phase wheel * 12 hours * number of teeth on the eclipse wheel / number of teeth on the hour wheel) / 24 hours ≈ 29.53 days.

[0010] Furthermore, the date-changing wheel is rotatably mounted on the base plate and meshes with the dual hour wheels; the date-changing wheel includes a date-changing wheel connecting part, a date-changing wheel rotating part, and a date-changing wheel fixing post that are fixedly connected from bottom to top, and the date-changing wheel connecting part meshes with the dual hour wheels; a rotating hole is provided on the base plate, and the date-changing wheel rotating part is accommodated in the rotating hole, and the date-changing wheel rotating part can rotate relative to the rotating hole; a support piece is sleeved on the date-changing wheel fixing post, and the support piece is fixedly connected to the end face of the date-changing wheel rotating part, so that the date-changing wheel is engaged with the base plate.

[0011] Furthermore, the date-changing head is sleeved on the date-changing wheel fixing post and is positioned above and in contact with the support plate component. The date-changing head, the support plate component, and the date-changing wheel are coaxially arranged. The date-changing head includes a turning head and a turning groove. The support plate component is provided with a date-changing stop pin, which is located in the turning groove. The rotation of the date-changing wheel drives the support plate component to rotate, thereby driving the date-changing stop pin to drive the date-changing head to rotate. The turning head corresponds to the teeth of the moon phase wheel. One rotation of the date-changing head can turn the moon phase wheel by one tooth.

[0012] Furthermore, the moon phase wheel is mounted on the central tube, which in turn is mounted on the hour wheel. The moon phase wheel, central tube, and hour wheel are coaxially arranged, with a gap between them, allowing them to rotate relative to each other. The moon phase wheel is located on the base plate on the side furthest from the hour wheel and can rotate relative to the central tube. A blocking disc is connected to the central tube and is positioned above the moon phase disc. Rotating the moon phase wheel changes the position blocked by the blocking disc, thus altering the displayed moon phase. A dial component is connected to the base plate. The dial component has a ring-shaped structure with a circular hole in the center. The diameter of the circular hole is equal to the diameter of the moon phase disc, enabling a panoramic large moon phase display on the watch dial.

[0013] Furthermore, the moon phase wheel is mounted on the moon phase axis, which is fixedly positioned near the edge of the base plate. The moon phase wheel and the moon phase axis are coaxially arranged, and the moon phase wheel is located on the base plate on the side away from the hour wheel, and can rotate relative to the moon phase axis. The obscuring plate is connected to the top of the moon phase axis and is positioned above the moon phase disc. Rotating the moon phase wheel can change the position obscured by the obscuring plate, thereby changing the displayed moon phase. A dial component is connected to the base plate, and a circular hole is provided near the scale on the dial. The diameter of the circular hole is equal to the diameter of the moon phase disc, so as to realize the moon phase display in a window on the watch dial.

[0014] Furthermore, a quick-release unit is provided on the base plate, which is connected to the moon phase wheel. Pressing the quick-release unit causes the moon phase wheel to rotate one tooth to adjust the current moon phase display. The quick-release unit includes a quick-release lever and a quick-release lever spring. The quick-release lever includes a tip, a tail end, and a hinged end. A hinged post is provided on the base plate, and the hinged end is hinged to the hinged post. The tip corresponds to the tooth of the moon phase wheel, and the tail end is located at the edge of the base plate. Pressing the tail end with a finger can drive the tip to move. The quick-release lever spring abuts against the quick-release lever, and the quick-release lever spring can reset the quick-release lever after it is pressed.

[0015] Furthermore, grooves are provided at the locations of the connecting unit, driving unit, display unit, and quick dial unit on the base plate. The connecting unit, driving unit, display unit, and quick dial unit are accommodated in the grooves on the base plate, so that the connecting unit, driving unit, display unit, and quick dial unit and the base plate form a plate-shaped module.

[0016] The modular moon phase display mechanism of this invention is ingeniously designed, easy to manufacture, has few parts, and is simple to assemble, making it suitable for mass production. Furthermore, the moon phase display mechanism can be installed as an independent module on a watch movement. By changing the position of the two long pins on the base plate, it can be adapted to various movements, demonstrating high adaptability. Moreover, by changing the position of the mounting obscuring plate, the position of the moon phase window can be freely changed, achieving diverse appearance displays at low cost and providing a good user experience.

[0035] To better understand the purpose, function, and specific design of this invention, the modular moon phase display mechanism of this invention will be described in further detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1-13 As shown, the modular moon phase display mechanism of the present invention includes a base plate 1, on which a connecting unit 2 is provided. In this embodiment, the connecting unit 2 is located at the center of the base plate 1. The connecting unit 2 is connected to a driving unit 3, and the driving unit 3 is connected to a display unit 4. The connecting unit 2, the driving unit 3, and the display unit 4 are all housed in grooves on both sides of the base plate 1. The connecting unit 2 is connected to the watch movement, and the movement of the watch movement can be transmitted to the driving unit 3 through the connecting unit 2, thereby causing the driving unit 3 to drive the display unit 4 to rotate to display different moon phases. A quick-release unit 9 is also provided on the base plate 1. Pressing the quick-release unit 9 can adjust the current moon phase display.

[0038] The base plate 1 has grooves at the locations of the connecting unit 2, driving unit 3, display unit 4 and quick dial unit 9. The connecting unit 2, driving unit 3, display unit 4 and quick dial unit 9 are housed in the grooves on the base plate 1 so that the connecting unit 2, driving unit 3, display unit 4 and quick dial unit 9 and the base plate 1 form a plate-shaped module.

[0039] Specifically, such as Figure 1 As shown, the connecting unit 2 includes a double hour wheel 22, which is coaxially and fixedly connected to the hour wheel 21 of the watch movement. The double hour wheel 22 is connected to the driving unit 3 to transmit the movement of the watch movement to the driving unit 3.

[0040] In this embodiment, the hour wheel 21 is a hollow tube with an hour wheel limiting flange 211 at one end. The double hour wheels 22 are sleeved on the hour wheel 21 and abut against the limiting flange. A through hole is provided at the center of the bottom plate 1, and an hour wheel receiving groove is provided at the through hole. The hour wheel 21 can be inserted into the through hole, and the double hour wheels 22 are accommodated in the hour wheel receiving groove.

[0041] The drive unit 3 includes a date-changing wheel 31. The dual-hour wheel 22 of the connecting unit 2 meshes with the date-changing wheel 31, and the dual-hour wheel 22 can drive the date-changing wheel 31 to rotate. The date-changing wheel 31 is coaxially connected to the date-changing dial 32, which corresponds to the moon phase wheel 5. The moon phase wheel 5 is connected to the display unit 4. The display unit 4 includes a moon phase disk 41 and a blocking disk 42. The moon phase disk 41 is printed with a moon pattern and multiple star patterns. The blocking disk 42 is positioned above the moon phase disk 41 to block the moon pattern. The moon phase disk 41 and the moon phase wheel 5 are coaxially and fixedly connected. The date-changing wheel 31 can rotate the moon phase wheel 5 by turning the date-changing dial 32, thereby driving the moon phase disk 41 to rotate, changing the area blocked by the blocking disk 42, and thus changing the moon phase displayed on the display unit 4. Figure 10 As shown, during the 360-degree rotation of the moon phase disk 41 in this embodiment, under the action of the blocking disk 42, the shape of the moon can be seen to gradually change from "new moon" to "full moon" and then from "full moon" back to "new moon".

[0042] like Figure 1-8 As shown, the date-changing wheel 31 is rotatably mounted on the base plate 1 and meshes with the double hour wheel 22. The date-changing wheel 31 includes a date-changing wheel connecting part 311, a date-changing wheel rotating part 312, and a date-changing wheel fixing post 313, which are fixedly connected from bottom to top. The date-changing wheel connecting part 311 is gear-shaped and meshes with the double hour wheel 22. A rotating hole is provided on the base plate, and the date-changing wheel rotating part 312 is housed in the rotating hole and can rotate relative to the rotating hole. A support piece 33 is sleeved on the date-changing wheel fixing post 313, and the support piece 33 is fixedly connected to the end face of the date-changing wheel rotating part 312 so that the date-changing wheel 31 is engaged with the base plate 1.

[0043] In this embodiment, the base plate 1 is provided with a day-changing wheel receiving groove, which is connected to the hour wheel receiving groove. The day-changing wheel 31 is rotatably disposed in the day-changing wheel receiving groove and meshes with the double hour wheel 22. The date-changing wheel 31 includes a date-changing wheel connecting part 311, a date-changing wheel rotating part 312, and a date-changing wheel fixing post 313, which are sequentially and fixedly connected from bottom to top. The date-changing wheel connecting part 311 is gear-shaped and meshes with the double hour wheel 22. A rotating hole is provided at the bottom of the date-changing wheel receiving groove, and the date-changing wheel rotating part 312 is housed in the rotating hole and can rotate relative to the rotating hole. A support piece 33 is sleeved on the date-changing wheel fixing post 313. The support piece 33 is fixedly connected to the end face of the date-changing wheel rotating part 312. The support piece 33 and the date-changing wheel connecting part 311 form a date-changing wheel slot to engage the base plate 1 in the date-changing wheel slot, thereby installing the date-changing wheel 31 in the date-changing wheel receiving groove. In this embodiment, the support piece 33 and the date-changing wheel rotating part 312 are connected by screws.

[0044] The date-changing head 32 is mounted on the date-changing wheel fixing post 313, and is positioned above and abuts against the support plate component 33. It is worth noting that the date-changing head 32, the support plate component 33, and the date-changing wheel 31 are coaxially arranged. Figure 8 As shown, the date-changing dial 32 includes a dial head 321 and a dial groove 322. A date-changing stop pin 34 is provided on the support plate component 33 and is located in the dial groove 322. The date-changing wheel 31 rotates to drive the support plate component 33 to rotate, thereby driving the date-changing stop pin 34 to drive the date-changing dial 32 to rotate. The dial head 321 corresponds to the teeth of the moon phase wheel 5. One rotation of the date-changing dial 32 can cause the moon phase wheel 5 to rotate once, that is, rotate one tooth.

[0045] In this embodiment, the moon phase wheel 5 is sleeved on the central tube 61. The moon phase wheel 5, the central tube 61, and the hour wheel 21 are coaxially arranged, with a gap between the central tube 61 and the hour wheel 21. The central tube 61 is inserted into a through hole at the center of the base plate 1 and is fixedly connected to the base plate 1. The moon phase wheel 5 is disposed on the base plate on the side away from the hour wheel and can rotate relative to the central tube 61. Preferably, a moon phase wheel receiving groove is provided on the side of the base plate 1 away from the hour wheel receiving groove. The moon phase wheel 5 is housed in the moon phase wheel receiving groove and can rotate relative to the central tube 61. It is worth noting that the moon phase wheel 5 and the date changing head 32 are connected to the pressure plate 51. The pressure plate 51 can restrict the moon phase wheel 5 within the moon phase wheel receiving groove, and the pressure plate 51 can also prevent the date changing head 32 from disengaging from the date changing wheel 31, thereby ensuring the positional relationship between the moon phase wheel 5 and the date changing head 32.

[0046] The moon phase wheel 5 is fixedly connected to the moon phase disk 41, and the moon phase wheel 5 and the moon phase disk 41 are coaxially arranged. The obscuring disk 42 is connected to the central tube 61 and is positioned above the moon phase disk 41. Rotating the moon phase wheel 5 changes the position obscured by the obscuring disk 42, thereby changing the displayed moon phase. Preferably, the obscuring disk 42 and the central tube 61 are fitted with a tapered hole shaft. In this embodiment, a pin fit is used. A taper is machined at the end of the central tube 61, and then the pin is passed through the hole on the obscuring disk 42 and inserted into the central tube 61 to install the obscuring disk. This ensures that the obscuring disk 42 and the central tube 61 can withstand multiple disassembly and reassembly when the assembly position of the obscuring disk 42 is changed or the obscuring disk 42 is replaced.

[0047] It is worth noting that the mounting position of the obscuring disk 42 is not fixed. The position of the moon on the lunar phase disk 41 is consistent with the position of the obscuring disk 42. The obscuring disk 42 can be mounted directly below, or directly above, to the left, to the right, or in other positions. Thus, by changing the mounting position of the obscuring disk 42, the position of the lunar phase window can be changed.

[0048] Preferably, the dual hour wheel 22 has 32 teeth, and the day-changing wheel 31 has 63 teeth. The transmission ratio between the day-changing wheel 31 and the dual hour wheel 22 is 0.50793651, meaning that every 23.625 (12*63 / 32=23.625) hours, the actuating head 321 actuates the moon phase wheel 5 by one tooth. The moon phase wheel 5 has 30 teeth, meaning that it takes 29.53125 days (30*23.625 / 24=29.53125) for the moon phase wheel 5 to complete one rotation of 30 teeth, or 29.53 days to complete one lunar phase cycle. This achieves a calendar with a lunar phase display cycle of 29.53 days.

[0049] like Figure 2-4As shown, a positioning groove 11 is provided on the base plate 1, and a positioning spring 8 is fixedly installed in the positioning groove 11. The free end of the positioning spring 8 is provided with a locking part 81, which can engage with the moon phase wheel 5 so that the moon phase wheel 5 can only rotate one tooth each time the date changer 32 moves it. In this embodiment, the locking part 81 is triangular, and the triangular locking part 81 engages between two adjacent teeth on the moon phase wheel 5. When the date changer 32 moves the moon phase wheel 5 to rotate, after the moon phase wheel 5 rotates one tooth, the locking part 81 will immediately engage with the moon phase wheel 5 again to prevent the moon phase wheel 5 from rotating too much.

[0050] The base plate 1 is also equipped with a quick-release unit 9, which is connected to the moon phase wheel 5. Pressing the quick-release unit 9 causes the moon phase wheel 5 to rotate one tooth, thereby achieving rapid adjustment of the moon phase display. The quick-release unit 9 includes a quick-release lever 91 and a quick-release lever spring 92. The quick-release lever 91 includes a tip 911, a tail end 912, and a hinge end 913. The hinge end 913 is hinged to a hinge post in the quick-release groove 12. The tip 911 corresponds to the tooth of the moon phase wheel 5. The tail end 912 is located at the edge of the base plate 1. Pressing the tail end 912 with a finger can drive the tip 911 to move. The quick-release lever spring 92 abuts against the quick-release lever 91, and the quick-release lever spring 92 can reset the quick-release lever 91 after it is pressed. Preferably, the base plate 1 is also equipped with a quick-release groove 12, and the quick-release unit 9 is housed in the quick-release groove 12. It is worth noting that by setting the toggle groove 322, when the quick-set unit 9 drives the moon phase wheel 5 to rotate, the moon phase wheel 5 will only drive the date changer head 32 to rotate independently, without affecting other components.

[0051] When the moon phase needs to be adjusted, press the end 912 of the quick-release lever 91. The tip 911 of the quick-release lever 91 can rotate the moon phase wheel 5 clockwise by one tooth. Then, under the action of the quick-release lever spring 92, the quick-release lever 91 returns to its original position, so as to facilitate the next quick-release operation of the moon phase, thereby realizing a quick adjustment of the moon phase.

[0052] like Figure 9 As shown, a dial component 7 is also connected to the base plate 1. In this embodiment, the dial component 7 has a ring structure with a large circular hole in the middle. The diameter of the circular hole is equal to the diameter of the moon phase disk 41, so that a panoramic large moon phase can be realized on the watch face.

[0053] The dial component 7 includes a dial 71 and a dial pin 72, which are fixedly connected to each other. In this embodiment, welding is used. The base plate 1 has corresponding dial pin holes, into which the dial pin 72 can be inserted to connect the dial component 7 to the base plate 1. Preferably, a dial retaining claw 73 is provided on the side of the base plate 1 away from the dial component 7. The dial retaining claw 73 can engage with the dial pin 72, thereby making the connection between the dial component 71 and the base plate 1 more reliable.

[0054] Example 2

[0055] The difference in appearance between this embodiment and Embodiment 1 is that Embodiment 1 displays the moon phase in a large window, while this embodiment displays the moon phase in a small window. Specifically, the connection unit 2 and the drive unit 3 in this embodiment have the same structure as in Embodiment 1, and will not be described in detail here. The difference in structure between this embodiment and Embodiment 1 is that the moon phase wheel 5 is positioned differently, and the display unit 4 is also positioned differently.

[0056] like Figure 14-15 As shown, in this embodiment, the moon phase wheel 5 is sleeved on the moon phase axis 62, which is fixedly mounted on the base plate 1. The moon phase axis 62 is fixedly mounted near the edge of the base plate, and in this embodiment, it is fixedly mounted near the six o'clock position on the dial 71. The moon phase wheel 5 and the moon phase axis 62 are coaxially arranged. The moon phase wheel 5 is mounted on the base plate on the side away from the hour wheel and can rotate relative to the moon phase axis 62. Preferably, a moon phase wheel receiving groove is provided on the side of the base plate 1 away from the hour wheel receiving groove, and the moon phase wheel 5 is housed in the moon phase wheel receiving groove. It is worth noting that the moon phase wheel 5 and the date changing head 32 are connected to the pressure plate 51. The pressure plate 51 can restrict the moon phase wheel 5 within the moon phase wheel receiving groove, and it can also prevent the date changing head 32 from disengaging from the date changing wheel 31, thereby ensuring the positional relationship between the moon phase wheel 5 and the date changing head 32.

[0057] The moon phase wheel 5 is fixedly connected to the moon phase disk 41, and the moon phase wheel 5 and the moon phase disk 41 are coaxially arranged. The obscuring disk 42 is connected to the top of the moon phase shaft 62 and is positioned above the moon phase disk 41. Rotating the moon phase wheel 5 changes the position obscured by the obscuring disk 42, thereby changing the displayed moon phase. Preferably, the obscuring disk 42 and the moon phase shaft 62 are fitted with a tapered hole shaft. In this embodiment, a pin fit is used. The moon phase shaft 62 has a blind hole with a tapered end. The pin is then passed through the hole on the obscuring disk 42 and inserted into the moon phase shaft 62 to install the obscuring disk. This ensures that the obscuring disk 42 and the moon phase shaft 62 can withstand multiple disassembly and reassembly when the mounting position of the obscuring disk 42 is changed or the obscuring disk 42 is replaced.

[0058] like Figure 16 As shown, a dial component 7 is also connected to the base plate 1. In this embodiment, the dial component 7 is circular. A circular hole is provided at the six o'clock position near the scale on the dial 71. In this embodiment, the hole is located at the six o'clock position, and the diameter of the circular hole is equal to the diameter of the moon phase disc 41, so that the moon phase can be displayed in a window on the dial 71. The connection method between the dial component 7 and the base plate 1 is the same as in Embodiment 1, and will not be described again here.

[0059] The connection unit 2, drive unit 3, display unit 4, and quick dial unit 9 of the present invention are all installed in the groove on the base plate 1 and form an independent module mechanism for displaying a moon phase. The base plate 1 is provided with a long nail 13. By assembling the long nail 13 into the corresponding dial nail hole of the watch movement, and using the original dial nail A, dial screw B, or dial claw C of the movement to hold the long nail 13, the independent module mechanism can be fixed to the watch movement. By changing the position of the long nail 13 on the base plate 1, the independent module can be assembled on different movements.

[0060] The modular moon phase display mechanism of this invention is ingeniously designed, easy to manufacture, has few parts, and is simple to assemble, making it suitable for mass production. Furthermore, the moon phase display mechanism can be installed as an independent module on a watch movement. By changing the position of the two long pins on the base plate, it can be adapted to various movements, demonstrating high adaptability. Moreover, by changing the position of the mounting obscuring plate, the position of the moon phase window can be freely changed, achieving diverse appearance displays at low cost and providing a good user experience.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

The date changing wheel can rotate the moon phase wheel by changing the date changing head, thereby changing the moon phase displayed by the display unit.

3. The modular moon phase display mechanism as described in claim 1, characterized in that, The date-changing wheel is rotatably mounted on the base plate and meshes with the dual hour wheels. The date-changing wheel includes a date-changing wheel connecting part, a date-changing wheel rotating part, and a date-changing wheel fixing post, which are fixedly connected from bottom to top. The date-changing wheel connecting part meshes with the dual hour wheels. A rotating hole is provided on the base plate, and the date-changing wheel rotating part is housed in the rotating hole and can rotate relative to the rotating hole. A support piece is sleeved on the date-changing wheel fixing post, and the support piece is fixedly connected to the end face of the date-changing wheel rotating part so that the date-changing wheel is engaged with the base plate.

4. The modular moon phase display mechanism as described in claim 2, characterized in that, The date-changing head is sleeved on the date-changing wheel fixing post and is positioned above and in contact with the support plate component. The date-changing head, the support plate component, and the date-changing wheel are coaxially arranged. The date-changing head includes a turning head and a turning groove. The support plate component is provided with a date-changing stop pin, which is located in the turning groove. The rotation of the date-changing wheel drives the support plate component to rotate, thereby driving the date-changing stop pin to drive the date-changing head to rotate. The turning head corresponds to the teeth of the moon phase wheel. One rotation of the date-changing head can turn the moon phase wheel by one tooth.

5. The modular moon phase display mechanism as described in claim 4, characterized in that, The moon phase wheel is mounted on the central tube, which in turn is mounted on the hour wheel. The moon phase wheel, central tube, and hour wheel are coaxially arranged, with a gap between them, allowing them to rotate relative to each other. The moon phase wheel is located on the base plate on the side furthest from the hour wheel and can rotate relative to the central tube. A blocking disc is connected to the central tube and is positioned above the moon phase disc. Rotating the moon phase wheel changes the position blocked by the blocking disc, thus altering the displayed moon phase. A dial component is connected to the base plate. The dial component has a ring-shaped structure with a circular hole in the center. The diameter of the circular hole is equal to the diameter of the moon phase disc, allowing for a panoramic large moon phase display on the watch dial.

6. The modular moon phase display mechanism as described in claim 4, characterized in that, The moon phase wheel is mounted on the moon phase axis, which is fixedly positioned near the edge of the base plate. The moon phase wheel and moon phase axis are coaxially arranged. The moon phase wheel is located on the base plate on the side away from the hour wheel and can rotate relative to the moon phase axis. The obscuring plate is connected to the top of the moon phase axis and is positioned above the moon phase disc. Rotating the moon phase wheel changes the position obscured by the obscuring plate, thereby changing the displayed moon phase. The base plate is connected to the dial components. A circular hole is provided near the scale on the dial. The diameter of the circular hole is equal to the diameter of the moon phase disc, so as to realize the moon phase display in a window on the watch dial.

7. The modular moon phase display mechanism as described in any one of claims 2-6, characterized in that, The base plate is equipped with a quick-release unit, which is connected to the moon phase wheel. Pressing the quick-release unit will cause the moon phase wheel to rotate one tooth to adjust the current moon phase display. The quick-release unit includes a quick-release lever and a quick-release lever spring. The quick-release lever includes a tip, a tail end, and a hinge end. The base plate is equipped with a hinge post, and the hinge end is hinged to the hinge post. The tip corresponds to the tooth of the moon phase wheel, and the tail end is located at the edge of the base plate. Pressing the tail end with a finger will drive the tip to move. The quick-release lever spring abuts against the quick-release lever, and the quick-release lever spring can reset the quick-release lever after it has been pressed.

8. The modular moon phase display mechanism as described in claim 7, characterized in that, The base plate has grooves at the locations of the connecting unit, driving unit, display unit, and quick dial unit. The connecting unit, driving unit, display unit, and quick dial unit are housed in the grooves on the base plate so that the connecting unit, driving unit, display unit, and quick dial unit together with the base plate form a plate-shaped module.
