Marking the start of a dive
24 | 25
The triangle on the rotating bezel can be aligned with the
minute hand by turning the rotating bezel anticlockwise.
The desired point in time (for example the time of enter-
ing the water at the start of the dive) can be set in this
way. You can read off the elapsed time (for example the
duration of the dive) on the rotating bezel. For safety rea-
sons, the rotating bezel can only be rotated in an anti-
clockwise direction. The rotating bezel is indexed audibly
and perceptibly in one-minute steps, and it is also legible
in the dark thanks to the luminescent markings.
If you are planning to use the watch to time dives, you
should be a certified open water diver and have the
water-resistance of your watch checked regularly by
an IWC service centre.
Cleaning the watch after diving
After diving – and especially after diving in seawater –
you should rinse your watch under running mains water.
This will prevent salt incrustation on the case, bracelet
and clasp.
