It is important to follow your employer's policies and procedures for clocking in and out to ensure accurate timekeeping. **

It's also possible that the winding mechanism is jammed or stuck, making it impossible to wind the clock. In any case, it's best to have a professional clock repair person examine the clock to determine the exact reason why it can't be wound up. **
