The optimal service cycle for your IWC timepiece is exclusive
to
your
watch
and
necessary interval between services will be determined by
your individual wearing habits; frequency of wear, your
environment/s, and the intensity of physical activity you
engage in. Your fine mechanical timepiece is an extension of
yourself and will run well for as long and smoothly as it is
treated. Therefore, we simply recommend you to continue
wearing your watch for as long as pleases you and to only
entrust it for a service if you notice a deviation from the regular
performance, function or timekeeping. It will then be our
pleasure to reinstate the premium performance with the
suitable service.
