Watch common sense:

1. How much is the error range of the watch normal?

Generally, the allowable error of mechanical watches is about 30 seconds per day, while that of quartz watches is about 15 seconds per month. The specific error must be determined according to the movement used by watches.

2. How long is the service life of the watch battery?

The service life of the battery usually ranges from 1 to 5 years, depending on the type, size, and function needed energy of the watch. For example, Chronograph watches consume more energy than watches that only indicate hours and minutes. When the second hand starts to jump every 4 seconds, it is time to replace the battery.
