Frequently Asked Questions - Seamaster Planet Ocean OMEGA

How to set the time zone on the Seamaster Planet Ocean?

Pull the crown out to position 2. Turn the crown forwards or backwards; the hour hand moves in 1-hour steps. Passing midnight changes the date. Push back to position 1 after adjustment.

How to use the helium escape valve?

During decompression, unscrew the valve crown to release the mechanism. The valve automatically releases gas when internal pressure exceeds external. Once pressure equalizes, screw the valve back down. Always keep it screwed when diving.

How to adjust the bracelet length?

Open the clasp. Free the longer section from the two slideways (A) and the catch (B). Adjust in the desired direction, then reinsert into the catch and slideways. Try on and readjust if necessary.

What is the water resistance of the Planet Ocean?

Water-resistant to 60 bar (600 metres / 2000 feet). Full water resistance requires the crown to be screwed in against the case.

How to wind the watch manually?

If the watch has not been worn for 60 hours or more, wind it by turning the crown in position 1 (normal position) clockwise. Avoid overwinding; stop when resistance is felt.

How to change the date?

Pull the crown to position 2. Turn the crown either direction until the hour hand passes midnight, which advances or reverses the date. Ensure the hour hand passes 7 pm for backward changes.

What is the power reserve?

The Caliber 8500 automatic movement has a power reserve of approximately 60 hours when fully wound.

How to open the foldover clasp?

Press the two pushers on either side of the OMEGA buckle and pull upwards to open. To close, push the clasp down with your thumb until you hear a click.

What warranty does the watch have?

The Seamaster Planet Ocean comes with a 4-year International Warranty from OMEGA.

Is the crystal scratch-resistant?

Yes, it features a scratch-resistant sapphire crystal with anti-reflective treatment on both sides. The case back is also sapphire crystal.

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.

1. Setting the time zone and correcting the date: pull the crown out to position 2. Turn the crown forwards or backwards, and 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.

NB: when changing the time zone backwards, it is necessary to move the hour hand back past 7 pm to ensure the date changes.

1. Time setting: 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.

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.
