FAQ & After-Sales Support. 1. Is it normal for an automatic mechanical watch to have a time difference? Yes. Automatic mechanical watches differ from quartz watches; they are powered by a mechanical movement, so a small daily time difference is normal. Daily accuracy may vary depending on the movement, wearing habits, wrist activity, temperature, watch position, power reserve, and magnetic environment. In general, an automatic mechanical watch may have a daily variation of about -20 to +40 seconds. This is a normal characteristic, not a quality problem. If the watch suddenly runs much faster or slower than usual, it may be caused by low power, shock, or magnetism; please contact us for assistance. 2. Why does the automatic watch stop? An automatic watch is powered by wrist movement. If not worn enough, or wrist movement is not active enough, the watch may stop due to insufficient power. For stable performance, we recommend wearing the watch at least 8 hours per day. If it has stopped, please wind it manually before wearing. 3. How to wind the automatic mechanical watch?
