  • Method and process for identifying watch pointer position and timekeeping of watch
    The invention relates to a method for controlling a watch, and in particular, to a method for identifying the position of a pointer of a watch and timekeeping of a watch. Due to the long time of the watch, the physical pointer may cause the time error due to various reasons. However, since the pointer and the surface are two systems that cannot feedback each other, the control unit of the watch does not know the relative positional relationship between the current physical metal pointer and the surface. In the process of solving the problem, the applicant proposed ...
