will require its removal for cleaning. To do this, the four
screws in the rotating ring are removed with the screw-
driver provided. The rotating ring can now be lifted
off upwards, and the exposed detent mechanism can
be brushed clean. The rotating ring is then replaced on
the case, and the four screws are fully retightened.
Important: The rotating ring should only be removed in
the event of malfunctions.
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. Testing must also be carried out after
exposure to exceptional stresses (e.g. extreme impact).
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.
Important: Your authorized IWC Official Agent must
perform a new water-resistance test every time your
IWC watch is opened and serviced.
Service for your GST Aquatimer
All the parts in this watch are manufactured from
top-quality materials. Nevertheless, a number of parts
are subject to natural wear and tear. It is particularly
important to ensure that points at which wear occurs
are always optimally lubricated and that contamination
of the oil caused by metal-to-metal abrasion is regularly
removed. This is why we recommend that you have a
maintenance service carried out on your watch about
every 5 years. Please contact an approved IWC Official
Agent or send your watch directly to the IWC Customer
Service Department in Schaffhausen.
