WATCH FUNCTIONS
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 60 hours or more, wind it
up with the crown in position 1.
2. Setting the time zone and correcting the date: pull the crown out to position
2. Turn the crown forwards or backwards, and only the hour hand will move
forwards or backwards by 1-hour intervals. By passing the hour hand over
midnight, the date can be changed forwards or backwards. Push the crown back
to position 1.
Synchronisation of the hour hand and the ’24-hour’ hand
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: 24 hours - hours – minutes – seconds. Pull the crown out 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.
SECOND TIME ZONE
Thanks to the ’24-hour’ hand with its triangular point, travellers can read the time
back home at a glance on the 24-hour scale at the centre of the dial.

HELIUM ESCAPE VALVE
How to use the helium escape valve? (fig. 2)
In its normal position (fig. 2.1), the OMEGA helium escape valve is perfectly
watertight thanks to the gaskets (B), but it is not functional, since it is screwed
down.
During the decompression phase, unscrew the crown of the valve in order to
release the mechanism (fig. 2.2). The valve is now watertight from the outside.
As the interior pressure becomes greater than the exterior pressure, it pushes the
gasket (A) out of its seating, thus releasing the gas (fig. 2.3). Once the pressure is
equalised, gasket (A) returns to its original position, pushed by the spring (C) (fig.
2.2).
This operation is automatically repeated several times during the decompression
phase. Once atmospheric pressure is reached, screw down the crown of the valve
(fig. 2.1).
Note: Even if the valve is unscrewed, and we strongly recommend that the valve
remains screwed down whenever the watch is immersed in water, the watch is still
water-resistant to a relative pressure of 5 Bar (50 metres). However, complete
water-resistance to the dial depth can only be achieved with gasket (B) and the
valve in the screwed down position.
FOLDOVER CLASPS
Opening (fig. 1): to open the clasp, press the two pushers on either side of the
OMEGA buckle and pull upwards.

Closing (fig. 2): put the watch on your wrist and close the clasp by pushing on it
with your thumb until you hear a click. (fig. 2).

Adjusting the length (fig. 3): free the longer section from the two slideways
(A) and from the catch (B). Adjust the bracelet in the required direction and
reinsert in the catch and the two slideways. Try the watch for size and readjust if
necessary.
