SET TING THE TIME AND CALENDAR
If you have not worn your watch for more than 60 hours the watch will normally stop at midnight, as
the changeover of the calendar uses a great deal of energy.
Warning:
If your watch has stopped between 10 p.m. and 2 a.m., you should on no account alter the date
using the rapid-advance date display with the crown in position 1. This would result in damage
to a component in the calendar mechanism which would require repair by a watchmaker. The same
applies to turning the crown too rapidly when setting the calendar.
We recommend winding the movement at least 20 times with the crown in position 0. Then pull the
crown out to position 2 in order to set the hour and minute hands to approximately 6 a.m. To set the
time accurately to the second, it is best to stop the movement as the small seconds hand passes 60.
Push back the crown to position 1. In this position, you can safely set the date to the previous day. If
you now pull the crown out to position 2, you can set the exact time in hours and minutes. If the date
does not jump to today's date when it passes 12 o'clock, you must wind the hour hand forward by
a further 12 hours. Once the hour and minute have been set to the correct time using this process,
push back the crown to position 0 to start the seconds hand.
