When you first wear it, it's better to hand wind the watch by turning the crown until it is full

Automatic self wind movement
All sub dials work fine
Waterproof: not suit for swim or shower
Some watches' crown is SCREW-IN style, you need UNSCREW first BEFORE adjust date or time.
When you press the side button or when you adjust date, DO set the time at 6:00 first, DO NOT set the time close to 24:00, just to protect the automatic movement!
 
Automatic Winding Watch
The watch will wind up itself when you are wearing it. Please wear everyday to make sure it works. If you
start wear it after a dormant period, please swing the watch several times or use hand to wind it alittle, it will start work again.
Four /Five /Six Hands Watch Calibration
Change the time to the period between 4 and 8 when adjusting the small dials (when pressing buttons), in order to protect the mechanical movement.
