Your Patek Philippe watch features a unique com-
bination of two useful and easy-to-use functions: the
patented Annual Calendar, which requires only one
manual correction per year; and the Travel Time
second time-zone system. Its technical original-
ity lies in consistently indicating the exact date
for local time. To provide this exclusive func-
tion, the engineers designed a new self-winding
movement in which the Travel Time mechanism
controls the Annual Calendar, allowing for for-
wards and backwards date correction. The second
time-zone display, by means of two central hour
hands, features an ingenious crown correction
system enabling the local time hand to be moved
forwards or backwards in one-hour increments.
The Annual Calendar, with its accelerated disk pas-
sages, ensures optimal synchronization of the date
and local time. Caliber 31-260 PS QA LU FUS 24H
is protected by eight patent applications for innova-
tions improving precision, performance, reliability,
safety and user-friendlinesss.
