The L.U.C Perpetual Twin model houses
a selfwinding mechanical movement,
which is equipped with two stacked
barrels (Chopard Twin technology) and
a perpetual calendar. Your wrist move

your watch. When fully wound, it has a

power reserve of 65 hours. If the watch
has stopped, wind it by hand before
wearing it by making about fifty clock
wise rotations of the crown. This is
equivalent to a power reserve of approxi
mately 35 hours.
Your watch is supplied with a corrector
tool enabling you to precisely adjust the
date, month, fouryear leapyear cycle
and the day.

REMARKS AND WARNINGS
– After each adjustment, the crown must
always be pushed back and screwed
in (depending on the model) in order to
guarantee its waterresistance.
– These operations must not under
any circumstances be performed
underwater, since this might damage
the movement.
– Never use a pen or any other instru
ment other than that supplied, as this
could damage the watch.
* However, years that are divisible by 100 are
only leap years if their number is also divisible
by 400: 2000 was thus a leap year, but 1700,
1800 and 1900 were not.
