Do we need to much care the watch zero error
Some people have obsessive-compulsive disorder, every day even if the error of a second should be adjusted. But in fact, it is normal that there is an error in the watch. Even the watch certified by the Observatory has a reasonable error range of - 4 / + 6S. Even if it's a quartz watch, the monthly error is within 10 seconds, it's already excellent.
