push the crown back to position 0. When setting the
time, please be aware that the date change always
takes place at midnight (24.00 h). If this change has
already taken place at 12 noon, you must move the
hands forwards by 12 hours.
Important: Although the watch is water-resistant in
positions 0, 1 and 2, the crown must nevertheless always
be screwed down again for normal use (position X).
Reading the time in the dark
The dial and the hour and minute hands and the marking
on the revolving ring of your watch are provided with
luminous elements which permit the time to be read
without problem, even in total darkness. The luminous
point at 12.00 serves as a reference point.
Marking the start of a dive
Rotation of the reset button in a clockwise direction
causes the bezel to rotate in the case, enabling the
triangle on the bezel to be aligned with the minute hand.
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 bezel. For safety reasons, the bezel can
only be rotated in an anti-clockwise direction. The
audible and perceptible indexing of the bezel takes
place in steps of one minute, and it is also legible in the
dark thanks to the luminous markings. The use of the
watch as a timer when diving requires an appropriate
diving sport training and regular inspection of the water-
resistance of the watch.
Cleaning the watch after diving
After diving – and especially after diving in seawater –
you should rinse your watch under flowing mains water.
This will prevent salt incrustation on the case, bracelet
and clasp.
Water-resistance
In order to ensure its perfect function, you must have
your watch inspected by an IWC service point at least
once a year. An inspection must also be carried out after
the watch has suffered abnormal stresses (shock).
If these inspections are not carried out as stipulated, or
if the watch is opened by unauthorized persons, IWC
will decline any guarantee or liability claims.
Recommendation: Your IWC Official Agent must
perform a new water-resistance test every time your
IWC watch is opened and serviced.
