CALIBRES 1120, 2500, 2520, 2610 (fig. I)
• 2627 (fig. III) • 2300 (fig. IX)
The crown has 3 positions, but only positions 1 and 3 are
functional for cal. 1120 jewellery version (fig. IV).
1. Normal position (wearing position): when pushed
into the case, the crown ensures that the watch is
water-resistant.
Occasional winding: if the watch has not been worn
for 44 hours or more, wind it up with the crown in
position 1.
2.
Date setting: pull the crown out to position 2, turn the
crown backwards and push it back to position 1.
For calibre 2610 only: date adjustment is made by
instantaneous jumps.
NOTE: date-setting is not recommended between 8pm
and 2am.
3. Time setting: hours – minutes – seconds. Pull the
crown out to position 3. The seconds hand will stop.
Turn the crown forwards or backwards. Synchronise
the seconds by pushing the crown back to position 1
to coincide with a given time signal.
Power reserve (cal. 2627)
Counter at 9 o’clock: small seconds.
Counter at 6 o’clock: power reserve indicator.
When the watch is fully wound, the power
reserve indicator hand points to 4/4. This
means that the power reserve is at least
44 hours.
