It can be wound by hand or automatically (with energy derived partly from the movements of the wearer's wrist) to drive the running of its caliber. If being worn with enough time every day, it do not need manual winding. For peoples don't move so much, we suggest them wind it manually every day to ensure that it will operate perfectly. How to wind the mechanical watch? When you first get the watch, please clockwise the crown (without pulling it out) for 20-30 times to power it up. If you don't wear the watch everyday, you need to wind it up and adjust time once you wear it.For every full-wind, the watch can keep about 36 hours.
