How to set your watch
Select your desired section
A
Winding crown
The winding crown is used to set the time and to wind the watch if it has not been worn. The winding crown is screwed down onto the case to ensure water resistance. It must be fully tightened after each manipulation.
Seconds hand
The hand indicating seconds.
Hour and minute hands
The hands on the watch that indicate the time.
Bezel
The unidirectional rotatable bezel allows precise measurement of dive times. For safety, the bezel rotates in one direction only. It is deliberately harder to turn when the zero marker (triangle) is in the 12 o'clock position to avoid inadvertent rotation.
