Abstract

The application discloses a mechanical watch running time adjusting device, which comprises a dial pin arranged on a balance wheel shaft and movably connected with the balance wheel shaft, and a hairspring movably connected with the dial pin; a fine adjustment device arranged on a balance wheel plate, the dial pin extends into the fine adjustment device, and both sides of the dial pin are connected with the fine adjustment device. In the application, the fine adjustment device is clamped on both sides of the dial pin, and only the fine adjustment device needs to be adjusted during adjustment. During adjustment, the position of the pointer can be adjusted by rotating a threaded rod, and the pointer is tightly attached to the pointer under the action of an elastic part, so that the pointer is prevented from being excessively adjusted, and the fine adjustment of fast and slow pointers is realized. Meanwhile, the pointer is prevented from jumping due to vibration under the clamping of the elastic part, and the running time of the watch is prevented from being affected.
