Furthermore, the ball bearing structure 12 includes: a fixed post a1, an elastic element a2 installed inside the fixed post a1, and a ball bearing a3 that is engaged with the elastic element a2 and protrudes from the upper surface of the fixed post a1. In this embodiment, a protruding engaging portion a11 is provided on one side of the fixed post a1, the elastic element a2 is a spring, and the side of the ball bearing a3 protruding from the fixed post is an inclined plane. In this embodiment, the protruding engaging portion a11 serves as a limiting function, and the inclined plane of the ball bearing a3 interacts with the ring module 2 to achieve unidirectional rotation.

[0035] In another preferred embodiment, please refer to Figure 7 The marble structure 12 described in this embodiment ， Includes: fixed column a1 ， Installed on the fixed column a1 ， The elastic element inside, and the part that is inserted into the elastic element and protrudes from the fixing post a1 ， The upper surface of the marble a3 ， Specifically, the fixed column a1 in this embodiment ， It is a hollow cylinder, the elastic element is a spring, and the marble a3 ， Partially protruding from the fixed post a1 ， Above, and the marble a3 ， Protruding from the fixed post a1 ， Part of it is a hemispherical structure. The marble structure 12 described in this embodiment ， The structural design enables the product to rotate in both directions.

[0036] In a preferred embodiment, the bezel module 2 includes: a bezel 21 with a plurality of movable bead grooves c1, a fixing ring 22 that is engaged within the bezel 21 and matches and fixes the movable bead 23 to the bezel 21, and a bottom ring 24 that covers the fixing ring 22 and is engaged and fixed into the bezel 21 and the watch case module 1 respectively. The bottom ring 24 has bottom teeth 241 formed on the side facing the watch case module 1 that match the ball bearing structure 12, and its inner sidewall has protrusions 242 for the protrusion inlet structure 13 to slide into / out of the buckle structure 13. The fixing ring 22 is a spring wire or a spring piece. The bezel 21 is annular, with movable bead grooves c1 formed on one side, and a placement groove c2 formed on the same side, the placement groove c2 communicating with the movable bead grooves c1. Specifically, the fixing ring 22 is snapped into the placement groove c2, and the movable clasps 23 are correspondingly snapped into the movable bead grooves c1, positioned by the movable bead grooves c1 and the fixing ring 22. The movable bead groove c1 has a buckle on the side facing the center of the bezel opening, which effectively limits the movement of the movable clasps 23.

The protrusion 242 is aligned with the protrusion inlet structure 14, allowing the protrusion 242 to slide into the inverted buckle structure 13. During the sliding process, the elastic element a2 is elastically compressed, and after being released, the elasticity returns to normal. At this time, each of the movable buckles 23 slides and engages with the engagement slot 11. By rotating the case module 1 and the bezel module 2 relative to each other, the movable buckles 23 slide along the engagement slot 11, thereby realizing the rotation function of this product. Rotating the protrusion 242 back to align with the protrusion inlet structure 14 allows the bezel module 2 to be disassembled in reverse, making disassembly relatively simple. It should be noted that alignment lines are formed on the outer walls of both the bezel module 2 and the case module 1 of this product. Users can use the alignment lines to confirm whether the protrusion 242 and the protrusion inlet structure 14 are aligned.
