Precautions

1. Because mechanical movement has a process of winding up, you need to first turn the pointer to a position above 55 scale (do not exceed 0), and then turn to the required scale

2. Mechanical movement: the bell rings in 1 minute. If you need to end the bell in time, for example, if you want to ring in 10 minutes, you can adjust the scale to 11 minutes.

3. Mechanical movement because it is of mechanical structure, it cannot rotate violently, otherwise it will easily cause timer damage.
