The allowable error for general mechanical watches is around 30 seconds per day, while for quartz watches, it is around 15 seconds per month. The specific error depends on the movement used in the watch. 2. What is the lifespan of a watch battery? The service life of a battery usually ranges from 1 to 5 years, depending on the type, size, and energy required for different functions of the watch. For example, a timepiece consumes more energy than a watch that only indicates hours and minutes. When the second hand starts to jump every 4 seconds, it's time to replace the battery. 3.
