2. Correcting the date: pull the crown out to position 2, turn the
crown backwards (forwards for calibres 2520, 8520, 8521, 8700,
8701, 8704 and 8705) and push it back to position 1.
For calibre 2610 only: date adjustment is made by instantaneous
jumps.
NB: date-setting is not recommended between 8 pm and 2 am.
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 for calibre 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.
Power reserve:
If the watch is not being worn, or during periods of low activity, the
power reserve indicator hand progressively moves anti-clockwise.
If the power reserve indicator hand is pointing to below 1/4, this means
that the watch’s power reserve is less than 10 hours. In this case, the
watch should be worn or wound by hand to prevent it from stopping.
During manual winding (crown in position 1) or when worn (self-
winding), the power reserve indicator hand moves clockwise.
