[0007] The minute dial is rotatably mounted inside the minute dial and connected to the wheel assembly;

[0008] The minute hand indicator frame is connected to the wheel assembly;

[0009] The advance wheel assembly includes the minute wheel, lower advance wheel, upper advance wheel, and hour gear. The minute wheel is mounted on the minute wheel shaft of the movement's minute wheel, which drives the minute wheel to rotate via the minute wheel shaft. The lower advance wheel is mounted on an external plate and connects with the minute wheel, which in turn drives the lower advance wheel to rotate. The upper advance wheel is mounted on top of the lower advance wheel and rotates synchronously with it. The hour gear is rotatably mounted on the minute wheel and meshes with the upper advance wheel.

[0010] As the minute hand wheel rotates 360 degrees, it drives the lower-level wheel to rotate 330 degrees.

[0011] Furthermore, a positioning arc is provided on the outer circumference of the minute hand wheel, and an arc-shaped notch is provided on the outer circumference of the lower passing wheel; during the connection between the positioning arc and the arc-shaped notch, the minute hand wheel rotates 30 degrees, and the lower passing wheel remains stationary.

[0012] Furthermore, the ratio of the pitch circle radius of the minute wheel to that of the lower intermediate wheel is 12:11; the gear ratio of the upper intermediate wheel to the hour wheel is 11:12.

[0013] Furthermore, the outer clamp is provided with several first positioning posts, and the minute dial is provided with first positioning holes corresponding to the several first positioning posts. The first positioning posts fix the minute dial through the corresponding first positioning holes.

[0014] Furthermore, a second positioning post is also provided on the outer clamp, and the lower wheel is rotatably mounted on the second positioning post.

[0015] Furthermore, a third positioning post is provided on the minute hand wheel, and the hour gear is rotatably mounted on the third positioning post.

[0016] Furthermore, a fourth positioning post is provided on the lower-level guide wheel, and the upper-level guide wheel is fixedly installed on the fourth positioning post.

[0017] Furthermore, a fifth positioning post is provided on the hour gear, and the hour dial is fixedly installed on the fifth positioning post and rotates with the hour gear.

[0018] According to the watch minute dial display structure of this utility model embodiment, the minute hand wheel drives the lower intermediate wheel, the upper intermediate wheel, and the hour gear, ultimately driving the hour dial to rotate. The minute hand wheel is equipped with a minute hand indicator frame. After the minute hand indicator frame and the hour dial rotate together 330 degrees (i.e., 0-55 minutes), the minute hand indicator frame rotates independently 30 degrees (i.e., 55-60 minutes) while the hour dial remains stationary. The rotation of the minute hand indicator frame aligns with the next hour. The solution of this application has a simple structure, is easy to install, has low production costs, and can be used more flexibly in watches, with a wider range of applications.

[0037] The guide wheel assembly 2 includes a minute hand wheel 21, a lower guide wheel 22, an upper guide wheel 23, and an hour gear 24. The minute hand wheel 21 is mounted on the minute wheel shaft 6 of the movement minute wheel (which is prior art and not shown in the figure), and the movement minute wheel drives the minute hand wheel 21 to rotate through the minute wheel shaft 6. The lower guide wheel 22 is mounted on the outer clamping plate 1 and is connected to the minute hand wheel 21. The minute hand wheel 21 can drive the lower guide wheel 22 to rotate. The upper guide wheel 23 is mounted on top of the lower guide wheel 22 and rotates synchronously with the lower guide wheel 22. The hour gear 24 is rotatably mounted on the minute hand wheel 21 and meshes with the upper guide wheel 23. When the upper guide wheel 23 is stationary, the hour gear 24 does not rotate with the minute hand wheel 21.

[0038] As the minute hand wheel 21 rotates 360 degrees, it drives the lower intermediate wheel 22 to rotate 330 degrees.

[0039] Furthermore, such as Figure 2 , 7 As shown in Figure 9, in this embodiment, a positioning arc 211 is provided on the outer circumference of the dividing needle wheel 21, and an arc-shaped notch 221 is provided on the outer circumference of the lower passing wheel 22; during the connection between the positioning arc 211 and the arc-shaped notch 221, the dividing needle wheel 21 rotates 30 degrees, and the lower passing wheel 22 remains stationary.

[0040] Furthermore, such as Figure 2 , 7 As shown in Figure 9, in this embodiment, the gear pitch circle radius ratio of the minute wheel 21 and the lower intermediate wheel 22 is 12:11; the gear tooth ratio of the upper intermediate wheel 23 and the hour gear 24 is 11:12.

The minute hand wheel 21 is equipped with a minute hand indicator frame 5. After the minute hand indicator frame 5 and the hour dial 3 rotate together 330 degrees (i.e., 0-55 minutes), the positioning arc 211 connects with the arc-shaped notch 221. At this time, the minute hand wheel 21 rotates, while the lower intermediate wheel 22, the upper intermediate wheel 23, the hour gear 24, and the hour dial 3 remain stationary. The minute hand indicator frame 5 rotates 30 degrees independently (i.e., 55-60 minutes), and the minute hand indicator frame 5 rotates to align with the next hour.
