摘要： The present disclosure relates to a metal wheel rotation device, comprising a watch body, which is provided with a watch case face cover and a watch case bottom cover at the upper and lower ends respectively, a watch case middle frame is fixedly arranged between the watch case face cover and the watch case bottom cover, a watch movement is sleeved in the watch case middle frame, and the watch movement is engaged in the watch case middle frame; an adjustment structure is provided in the middle position of one side of the watch case middle frame corresponding to a watch movement button, the adjustment structure is fixedly connected to the watch case middle frame by screws. This design transfers the adjustment structure of the watch case to the middle position. A rotating structure is composed of a rubber ring, a threaded rod metal structure and an external handle head. The rotating structure drives the watch movement to adjust and rotate. The ferrule is combined on the threaded rod metal structure, and the ferrule mainly serves as an adsorption and anti-slip effect, so that the original adjustment structure of the watch movement can be driven to rotate simultaneously when the external handle head rotates. The adjustment structure of the present disclosure is more convenient to use and has a more symmetrical appearance.
