Note: date, day, month or moon phase cor-
rections should not be performed between
10 p.m. and 2 a.m. This is because the auto-
matic date-change mechanism is already in
action between these times.
OPERATING THE CHRONOGRAPH
The central seconds hand on the Master
Control Chronograph Calendar displays the
chronograph seconds to the nearest quarter of
a second.
The counter located at 3 o’clock tallies the
minutes up to 30 minutes (after 1 revolution it
will start counting another 30 minutes).
- Push-piece at 2 o’clock: this push-piece starts
and stops the chronograph function.
- Push-piece at 4 o’clock: This push-piece
resets the 30 minute counter and the central
seconds hand.
Note: When timing is in progress, resetting
is not possible. This push-piece is locked
and forcing it may harm the mechanism’s
functioning.
