Positioned on the side of the watch is the crown,

which is used for setting the time

and adjusting the time zone and the date.

In its normal wearing position,

the crown ensures the watch is fully water resistant.

It has to be unscrewed before the time can be set.

Although the watch is self-winding,

when the crown is in this position,

it can be wound forward for extra power.

To set the time,

pull the crown out two clicks to its furthest position.

The seconds hand will stop.

Turn the crown forward or backward

to move the hour and minute hands to the desired time.

You can adjust the time zone easily

to accommodate time changes when you travel.

Pull the crown to position 2

and turn it forward or backward to move the hour hand.

This will not stop the minute and seconds hands.

To adjust the date forward, advance the hour hand past midnight.

To adjust the date backward,

move the hour hand back past 7 pm to ensure it changes.

To re-seal the crown, make sure it’s in position 1.

Then push it firmly while screwing it clockwise.

The bezel with its dot and scale is used for indicating elapsed time,

for example, during a dive.

By positioning the luminescent dot at the minute hand

when starting the dive,

the diver can easily see how much time has elapsed.

The bezel rotates only in one direction.

This ensures that

the elapsed diving time cannot be accidentally decreased.

To reset the bezel, rotate it all the way around.

For ease of reading in low-light conditions,

the watch’s hands and applied indexes are coated with Super-LumiNova

which emits a blue light.

The exceptions are

the minute hand and the dot on the bezel.

Their coating emits a green light,

distinguishing them from the other hands

and allowing comfortable reading of the elapsed time,

even under water.

The chronograph is used

for measuring time periods of up to 12 hours.

To start or stop timing,

press the upper pusher located at 2 o'clock.

The OMEGA Co-Axial calibre 9300,

has 12 hour and 60 minute chronograph hands placed

on the same counter at 3 o’clock.

This combined hour and minute counter can also be used

as a second time-zone indication.

Simply start the chronograph at midnight or noon

in the other time-zone.

To reset the chronograph hands,

press the lower pusher located at 4 o'clock.

A feature created specifically for professional divers

is the helium escape valve.

When they are working at great depths,

these divers spend several days in a pressurized environment.

Here they breathe

a special blend of gasses containing helium.

The small helium molecules are able

to push past the seals and enter the watch case.

To operate the valve, unscrew it

as the decompression process is taking place.

The helium escape valve allows these molecules

to escape in a controlled fashion.

Your metal bracelet can easily be extended

to fit over a wetsuit.

First, press the two pushers on either side of the clasp

and release the bracelet.

On the opposite side,

unclip the extension and elongate the bracelet further.

To re-set the bracelet to its original length,

simply reverse the process.

Carefully replace the extension

so that it clicks properly into position.
