adjusting the watch for a date change
Pull the crown out to position 2.
When changing date while travelling towards the West, such as going from
america to asia, you move on to the next day:
- adjust your watch by moving the hands forward until you reach the following
day and the local time.
- you can also use the corrector push-piece to move the date forward.
When changing date while travelling towards the east, you move back to the
previous day. in this case, the watch will indicate one day earlier.
this date display error can be corrected by twice turning the hands back by
12 hours each time, so as not to go back beyond the red zone (i.e. between
8.00 pm and 4.00 am).
the correction is performed as follows:
- the first 12-hour wind-back is performed in the afternoon between 4.00 pm
and 8.00 pm. For example, if you perform this operation at 8 pm, the day/
night indication dial of your watch will show 8 am instead of 8 pm after this
first turn.
- the second 12-hour windback is performed the following morning between
4.00 am and 10.00 am. For example, if you perform this operation at 8 am,
your watch will display 8 am again (current time with the correct date).
the date indicator will once more be synchronised with the local date.
