SERVICING YOUR
PORTUGIESER PERPETUAL CALENDAR 42
The optimal service cycle for your IWC timepiece is exclusive to your watch and unique lifestyle. The
necessary interval between services will be determined by your individual wearing habits – such as
the frequency of wear, the environment(s) you live in and the intensity of physical activity you engage
in. Therefore, we simply recommend that you continue wearing your watch for as long as you please
and to only entrust it for a service if you notice a deviation from the regular performance, function or
timekeeping.
