Setting the time and date

There are 3 positions for the crown with each designated for a different winding functionality. 

  1. Unscrew the crown to the first position to manually wind the watch.
  2. Pull the crown out to the second position to change the date. Turn the crown clockwise until you reach the correct date. Refrain from changing the date between the time of 10pm to 2am.
  3. Pull the crown out to the furthest position from the watch base to set your watch's time. When the crown is in this last position, the second hand stops in order for you to accurately set the time.

After winding your watch, press the crown back into its original position at the base of the watch, then screw the crown down to ensure the watch is water-tight.
