Time100 Dual Time Skeleton Sun&Moon PhaseAutomatic Luminous Mechanical Men's Watch # W60025G.01D
Notes: This is a mechanical watch which has special power. It is normal for a mechanical watch to have 45 seconds gap a day. 1. When you are first to wear it, the watch must be wound by hand and wave your hand a few times, then the watch will work fine. 2. After fully wound, a common mechanical watch can run for 40 hours a high-end watch can run for 3-4 days. 3. Theoretically, how long a watch can run when fully wound will vary slightly due to different caliber design, but, generally, power originating from daily wearing is not enough to keep a watch fully wound. 4. If you can wear your watch for 8-10 hours with efficient arm movement in one day, then it will keep proper time in the next day. 5. If you do not wear your watch all day or your arm movement is insufficient, then it might stop running in the next day. Here, "insufficient" indicates that your arm wearing your watch keeps still or just moves slightly, which might not have your watch wound.
