POSITION A MANUAL WINDING Your Yema watch is equipped with a self-winding mechanical movement, this means it is wound automatically by wrist movements. To ensure optimum winding, wear your watch daily. Before you first use the watch or if unworn for a long period of time, you will need to wind it manually by turning the crown clockwise.

POSITION B DAY / DATE SETTING To adjust the Day/Date, pull the crown out to POSITION B. Then and turn the crown clockwise or counter-clockwise to change the Day/ date setting. IMPORTANT: Do not make date adjustments when the time on the watch reads between the hours of 9:00pm and 3:00am.
POSITION C TIME SETTING To set the time, you must first pull the crown out into POSITION C and turn in any direction to set the correct time. The Perpetual Seconds Hand (sub counter at 9 o’clock) remains stationary to allow the watch to become synchronized for precise accuracy.
