World time operation
Your Master Compressor Extreme W-Alarm watch has an
ingenious world time display system, enabling it to indicate the
time in 24 of the world’s cities simultaneously.
Instant reading of the time in the 24 time zones of the world
is thus possible thanks to the city disc and the 24-hour rotat-
ing ring. This reading requires a pre-setting, which consists of
setting the local time by positioning the corresponding city
at 6 o’clock. The time in the city selected corresponds to the
mechanism reference time.

How to proceed
- Set the hour and minutes on your watch as per the instruc-
tions above (local time).
- Crown C (only one position, not pulled out) moves the city
disc : turn the crown in one direction or the other to bring
up the city corresponding to your local time opposite the
numeral “6” on the dial (i.e. 6 o’clock position).
- The 24-hour ring then indicates the same time as your
local time opposite the numeral “6” and hence opposite
the reference city that you have placed in this same posi-
tion.
Once this pre-setting has been performed :
- The 24-city disc no longer moves.
- The 24 hour ring will turn along with the local time ring
(time in your reference city), but completes one turn of the
dial in 24 hours. It updates the time for each of the cities at
the same time as the local time.
- You can thus at any moment read the time in any city indi-
cated on the city disc, by putting together the hour dis-
played on the 24-hour ring opposite the city in question
with the minutes on your central hands.
- If you travel to another time zone, you will need to repeat
the operation to bring up the new reference city corre-
sponding to the new time zone at 6 o’clock.
Nota bene : the few regions in which the official time differs
by a fraction of an hour (India, Iran, Nepal) do not appear
on the city disc.
Case shock-absorber system
Your watch has a novel case system which allows it to absorb
the shocks sustained, and thereby protects the watch move-
ment. The case is built in two parts :
- The central part, in titanium, is a water-resistant case which
protects the movement.
- The external part consists of the lower support.
The case containing the movement is housed in the support
and can move vertically. In case of an impact, an airbag system
dampens the force.
Interchangeable strap system
The base of your watch case is fitted with an integrated inter-
changeability system allowing the strap to be changed easily.
It consists of a pushbutton which shifts part of the space
between the lugs to release the strap’s spring bar from its
housing in the lugs.
Removing the strap sections from the case
- Hold the back of the watch case between the thumb and
forefinger of one hand (A).
- Hold the strap section between the thumb and forefinger
of your other hand (B).
If setting is performed at 5 o'clock, you
observe that the 24-hour ring indicates
"5" opposite the city at 6 o'clock.
Two hours later, at 7 o'clock, you
observe that the 24-hour ring has
also moved forward, to indicate "7"
opposite the city at 6 o'clock. The time
in all time zones can be read instantly.
