WATCH FUNCTIONS
The crown has 3 positions:
1. Normal position (wearing position): when the crown is positioned against the
case, the crown ensures that the watch is water-resistant.
Occasional winding: if the watch has not been worn for 55 hours or more, wind it
up with the crown in position 1.
2. Correcting the date: pull the crown out to position 2, turn the crown
backwards, then push the crown back to position 1.
NB: the date cannot be corrected between 9 pm and 12.30 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.
CHRONOGRAPH FUNCTIONS
• Pusher A: start – stop, start – stop, etc
Timing to 1/8 of a second for up to 12 hours.
• Pusher B: reset (after a stop).
Note: resetting/zeroing of the sub dials must only be carried out after the
chronograph has stopped. Never push the chronograph’s two pushers (A and B)
simultaneously.

CHRONOGRAPH FUNCTIONS WITH SPLIT-SECONDS
The split-seconds function allows split times to be recorded whilst the
chronograph is running.
1. Start the chronograph by pressing pusher (A) (start).
2. To record a split time, press pusher (C). The split-seconds hand (D) stops,
indicating the split time, whilst the chronograph continues running.
NB: the split time should be read immediately, since the chronograph totalisers for
hours (G), minutes (E) and seconds (F) continue to measure the elapsed time.
3. Press pusher (C) for the split-seconds hand to catch up with the chronograph
seconds hand (F).
4. To record a new split time, start from step 2 above.
5. Press pusher (A) to stop the chronograph.
6. Press pusher (B) to reset.
NB: the split-seconds hand (D) must have caught up with the chronograph
seconds hand (F) as explained in step 3 before the chronograph mechanism is
reset/zeroed.
