The triangle on the internal rotating bezel can be aligned with the
minute hand by turning the external rotating bezel. The desired
point in time (e.g. the time of entering the water at the start of the
dive) can be set in this way. You can read off the elapsed time
(e.g. the duration of the dive) on the internal rotating bezel. For
safety reasons, the internal rotating bezel can only be rotated in
an anticlockwise direction. The rotating bezel is indexed audibly
and perceptibly in one­minute 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.
