The second time-zone dial shows the same time as displayed
by the large hands : this is normal, since you have displayed
the city located in your own time-zone in the window at 6
o’clock. Your two displays are now synchronized.
Selecting the city : automatic display of the hours and
minutes in the second time zone
Your watch is running, pre-adjustment has already been
performed and you have not modified the local time since
this operation. If this is not the case, first proceed to the
synchronization pre-adjustment.
Note : before selecting the city (crown A), make sure that
the synchronization crown (crown B) is in position 1 (not
pulled out). Failure to comply with this order might damage
the adjustment mechanism.
Crown A
Turn the compression key to the «open» position in the
direction of the arrow. Then pull crown A out to position
2. Turn the crown backward or forward and display the
city required for the second time zone in the rotating disc
at 6 o’clock, opposite the triangular marker. The time in the
selected time zone is automatically displayed on the small dial,
and thanks to the AM/PM aperture, you can check whether it
is morning or afternoon.
Push the crown back to position 1 and turn the compression
key to the «closed» position in the direction of the arrows.
Note The fact that it is necessary to pull on crown A to actuate
the city disc constitutes a security measure. In particular, it
prevents any unintentional rotation of the city mechanism.
Special cases :
Setting the Master Compressor Geographic model
for daylight saving time changes
Local time in certain countries is moved forward one hour
during the summer months. However, there is no single rule
applicable worldwide.
The Master Compressor Geographic model is mechanically
programmed and thus cannot take account of these local
variations. However, since it is possible to synchronize the two
displays, the problem is easily resolved by your watch.
A.You live in a country that changes time in summer; for
the second time zone, you want to display a city that does
not change time.
Turn the compression key of crown B to the «open» position
in the direction indicated by the arrow.
- Moving from winter time to summer time :
Pull crown B out to position 3 and move the time one hour
forward (local time). Push crown B back in to position 2
and move the hour on the second dial one hour backward.
Push the crown back to position 1.
Your watch shows the summer time on the main display
and winter time on the small dial.
- Changing from summer time to winter time :
Pull crown B out to position 3 and move the time one hour
backward (local time). Push crown B back in to position
2 and move the hour hand on the second dial one hour
forward.
You are now synchronized with GMT again.
Turn the compression key to the «closed» position in the
direction indicated by the arrows.
B.You live in a country that does not change time in
summer; for the second time zone, you want to display a
city that has changed time.
Turn the compression key of crown B to the «open» position
in the direction indicated by the arrow. Pull crown B out to
position 2 and move the hour on the second dial one hour
forward. Push the crown back to position 1.
Turn the compression key to the «closed» position in the
direction indicated by the arrows. You have thus automatically
adopted the exact summer time displayed on the second dial
for those countries which have opted for this system.
For the other countries, however, the times will have to be
corrected by deducting one hour. After time setting, you will
need to check the time zone calibration.
