People travelling
East
, for example from London to Hong Kong, should
pull the crown out to position 2 and move the hour hand forwards
(in this case by 8 hours). The table above can be used to calculate any
time difference.
People travelling
West
, for example from London to New York, should
pull the crown out to position 2 and move the hour hand backwards
(in this case by 5 hours). The table above can be used to calculate any
time difference.
In both cases, the '24-hour' hand allows travellers to read the time
back home – London, in our example – at a glance, using the 24-hour
scale on the dial. The second time zone – in this case Hong Kong or
New York – is read off the dial in the usual way. Each time the hour
hand crosses midnight, the date jumps forwards or backwards, depen-
ding on whether the hour hand is moved forwards or backwards.
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 44 hours
(calibres 1128, 2628) or 55 hours (calibre 3603) or more, wind it up
with the crown in position 1.

2.
Setting the time zone:
pull the crown out to position 2 and turn
it. Only the hour hand moves (clockwise or anticlockwise), without
affecting the precision of the minutes or seconds. If the hand moves
past midnight, the date changes automatically. Push the crown
back to position 1.
Correcting the date:
pull the crown out to position 2, turn it
forwards or backwards to change the date each time the hour hand
passes midnight. The date moves forwards (or backwards) one day.
Repeat until the required date is obtained. Push the crown back to
position 1.
Synchronisation of the hour hand and the '24-hour' hand
(calibre 1128 - fig. VI)
The triangle on the rotating bezel must point to 12 o’clock on the
dial.
Pull the crown out to position 2 and turn it to synchronise the
hour hand with the time indicated by the '24-hour' hand on
the 24-hour scale on the rotating bezel. Make sure you set the
hour hand in the correct half of the day! Push the crown back to
position 1.
Synchronisation of the hour hand and the '24-hour' hand
(calibre 2628 - fig. VII, calibre 3603 - fig. XX)
Pull the crown out to position 2 and turn it to synchronise the hour
hand with the time indicated by the '24-hour' hand on the 24-hour
scale in the centre of the dial. Make sure you set the hour hand in
the correct half of the day!
After synchronising the hour hand with the '24-hour' hand, you
must set the local time on your watch. Push the crown back to
position 1.
3.
Time setting:
hours – minutes – seconds. Pull the crown 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.
