2 operation: setting the local hour hand
nd
Crown A
The compression key is still in the "open" position.
Then pull crown A out to position 2.
Move the main hour hand (local time) forward or backward
past midnight to bring it to the desired time, in order to take
account of the date indicator:
- You have turned the crown clockwise: if the date moves
forward when the hands pass midnight, you are moving
into the morning.
- You have turned the crown anti-clockwise: if the date
moves backward when the hands pass midnight, you are
moving back into the evening.
Once the operation is complete, push the crown back into
position 1 and turn the compression key to the "closed" posi-
tion in the direction of the arrows.
Correcting the local time setting when travelling and chang-
ing between summer time/winter time
Go directly to the 2 operation to quickly set your watch for
nd
simple hour changes (in cases not involving minute or date
changes). For example, to set the time for your new local
time-zone when travelling, or changing between summer time
and winter time.
Make sure to turn the compression key to the "open" posi-
tion in the direction of the arrow first, whenever you want to
change the local hour hand in this configuration.
Selecting the city for automatic time display of the second
time-zone
Following the above settings, the hour hand in the second
time-zone dial will indicate the same time as the hour hand
in the main dial. This phenomenon is normal, since the dial at
6 o'clock indicates the city in your local time-zone. The city
selection function is operational.
NB: before selecting the city, you need to ensure that the syn-
chronisation crown (crown A at 2 o'clock) has been pushed
back into position 1 (not pulled out). Failure to comply with
this order might damage the correction mechanism.
Crown B
Turn the compression key to the "open" position in the direc-
tion of the arrow.
Then pull crown B out to position 2.
Turn crown B clockwise or anti-clockwise, to display the city
desired for the second time-zone at 6 o'clock opposite the
triangular marker. The hour for the selected time-zone will
then be displayed automatically in the sub-dial at 9 o'clock,
directly with 24-hour accuracy.

Case functions
Diving bezel
The Master Compressor Diving Pro Geographic watch is
equipped with a unidirectional rotating bezel (i.e. one that can
only be turned anti-clockwise), with a mark every minute.
It can measure a particular time using the luminescent white tri-
angular marker as a reference point in relation to the hour hand
or minute hand.
To use the diving bezel, you need only grip it with two fingers
and turn it anti-clockwise to the desired position.
Mechanical depth gauge
Please consult the explanations and advice beforehand in the
chapter 'Mechanical depth gauge on the Master Compressor
Diving Pro Geographic watch' in the introduction section.

Operating underwater
No action is required on your part is required for the depth
gauge to work underwater. It reacts to the water pressure
and transmits the depth information to the hand on the dial
via a transmission circuit, which includes the two components
known as the "rack" and "central pinion", which you can see
via the openworked dial.
The display on the dial is indicated by the blue hand on a
logarithmic scale from 0 to 80 metres. This is graduated for
each metre from 0 to 50 metres, then every two metres from
52 to 80 metres.
Operating out of water
The depth gauge function was created to be easily visible
even in a non-aquatic environment. At any time, you can
lightly press on the depth gauge membrane head, to observe
the movement of the hand according to the force of the pres-
sure. You can increase the pressure until the maximum hand
reading is reached (80 metres). The hand will return to its
'zero' position when you release the pressure.
