Your Reference 5235 Annual Calendar Regulator
unites an unconventional dial with the conveni-
ence of a self-winding movement featuring a
Spiromax
ment in Silinvar
date, day, and month, which needs to be manually
corrected only once a year.
winding crown
The winding crown is used to manually wind the
watch (position 1) and to set the time (position 2).
winding
Your watch incorporates a self-winding movement.
The movements of your wrist set a centrifugal mass
in motion; this tensions the mainspring which
stores the energy. When you take off your fully
wound watch, it will continue to run for up to
48 hours. When it has stopped after depleting the
power reserve, it can be rewound by hand (about
10 clockwise turns of the crown). Please wind the
watch before you put it on. This way, you can avoid
lateral pressure on the winding stem which in the
course of the years could damage the stem tube.
