First, the basic knowledge of mechanical watches:
1. Fully automatic winding mechanical watch: It is automatically wound by the swing of the arm, so it must be worn for more than 8 hours every day to ensure accurate timing. It is also possible to supplement the energy by hand-winding by rotating the “turned” clockwise about 15 turns (without pulling out).
      2, manual winding mechanical watch: need to manually wind up (“put” does not pull out, clockwise rotation) watch can be normal to walk, usually “turn” can be rotated 15 times (such as too much may damage the watch The chain), after the clockwork is full, the watch can walk continuously for about 24 hours.
