Water resistance of your
ENDEAVOUR PERPETUAL CALENDAR
The ENDEAVOUR PERPETUAL CALENDAR is protected
against penetrating moisture by extensive seals. To ensure
that it continues to work perfectly, the water resistance of
your ENDEAVOUR PERPETUAL CALENDAR must be checked
by a specialist each time that the case is opened. In general,
we recommend that you have the water resistance of
your watch checked at least once a year by an authorised
specialist. Doing so will ensure that you can rely on the
water resistance of your ENDEAVOUR PERPETUAL CALENDAR.
