What factors affect watch timekeeping deviation?

　　Influenced by various factors in daily use, it is inevitable that any watch will experience some deviation in timekeeping. So, what are the common factors that affect watch accuracy? What is the typical accuracy range for a watch? Below, we provide a detailed explanation for your reference.

　　Analysis of factors affecting watch accuracy

　　1. Quality issues with the watch itself, such as automatic winding failure or rotor malfunction, can cause inaccurate timekeeping;

　　2. Changes due to factors such as temperature, magnetic fields, shocks, vibrations, and altitude. Watches should avoid proximity to electrical appliances like speakers, televisions, and mobile phones as much as possible.

　　3. For the elderly, office workers who sit for long periods and exercise little, or individuals who naturally possess a stronger personal magnetic field, timekeeping can also be affected.

　　Watch accuracy range

　　The testing method is very simple. First, fully wind the German watch, then align the hours, minutes, and seconds of the German watch under test with a standard time source to synchronise them. Next, place it flat and let it run for 24 hours, then compare it with the standard time to record the deviation. Repeat this process in sequence, testing and recording the running deviation of the German watch in the dial-down, crown-down, crown-left, and crown-up positions.

　　For example: the static test results are dial-up 20 seconds/day, dial-down 20 seconds/day, crown-down -5 seconds/day, crown-left 25 seconds/day, crown-right 10 seconds/day, resulting in an actual daily wearing deviation of 15 seconds/day for the German watch.
