Diving function
Diving time can be measured using the unidirectional turning flange. For safety reasons,
it can only be turned counter clockwise.
Before starting the dive, turn the dedicated crown counter clockwise to unscrew
it until position 1. Then, turn the crown clockwise until the diving indicator is in front
the minute hand. Diving time can be read directly on the flange's scale, for example
below: 30 minutes.
