The error range of the watch is ±30 seconds/day (30 seconds is qualified; 20 seconds is accurate; 10 seconds is accurate; 5 seconds is accurate), and the average error range of the movement certified by the observatory is -4 seconds /Day to +6 seconds/day. The official error value of the accuracy of common mechanical OEM watch movements: Japanese SEIKO6R15 movement: daily difference +25 to -15 seconds; Swiss ETA movement: daily difference +20 to -15 seconds; astronomical observatory certification (COSC): daily difference +6 to -4 seconds.

Quartz electronic watches are much more accurate than mechanical OEM watches. The daily error of ordinary quartz watches is less than 0.5 seconds, which is one-tenth of that of mechanical watches. The daily error of the quartz watch is generally ±0.5 seconds (superior product).

3. Watches are often exposed to a strong magnetic field and are easily magnetized. The balance spring of the oem watch is magnetized, and the time of the watch will be inaccurate. You can get it to the radar after-sales repair center for inspection and adjustment to restore the watch to the normal error range. Inside.

Understand the error of a general watch. In addition to the above factors, bumps, movement oil, etc. will also cause oem watch errors. Every watch ai'hao'zhe should remember to maintain your watch frequently.
