Water Resistance - Patek Philippe 5275 Manuel D'instructions

An hour strike in passing
An exclusive striking mechanism makes the
Reference 5275 a delight for the ear as well as the
eye. At the top of each hour, a hammer strikes a
single blow on a gong, in perfect synchrony with
the instantaneous jump in the hour aperture. This
completely new function recalls Patek Philippe's
unparalleled mastery in the field of striking
watches. The sound indication may be deactivated
at will, using the small slide at 10 o'clock. A
patented lifting lever secures the system against
accidental mishandling.
Instructions
To activate the acoustic signal, operate the small
slide switch (ON/OFF) at 10 o'clock (3). This will
cause a hammer to strike every full hour on a gong.

WATER RESISTANCE

Although your watch is equipped with a water-
resistant crown, it is not protected at all against
the ingress of moisture.
Therefore, exercise care to ensure that liquid does
not come into contact with your watch.
