1 Introduction
Special recommendations
What must I do to ensure that my OMEGA watch provides me with excellent service for many years? Magnetic fields: avoid contact with magnets, or putting your watch on top of loudspeakers, refrigerators or magnetic cases for iPads or other tablets, since such objects generate magnetic fields which could disturb the functions of your watch. Watches that include Master Co- Axial or Master Chronometer in their name are unaffected by magnetic fields up to 15,000 gauss (1.5 tesla). Swimming in the sea: always rinse your watch with fresh water afterwards. Shocks: whether physical, thermal or other, avoid them. Crown: always push the crown back into the case (position 1) to prevent water from entering the mechanism. Do not operate the crown under water. Screw-down crown: always ensure that the crown is screwed back in completely to prevent water from entering the mechanism. Do not operate the crown under water. Cleaning: for metal bracelets, rubber straps and water-resistant cases, use a toothbrush and soapy water for cleaning and dry with a soft cloth. Chemical products: avoid direct contact with solvents, detergents, perfumes, cosmetics, insect repellents, etc., since they may damage the bracelet, case or gaskets. Temperature: avoid exposure to extreme temperatures (greater than 60°C, or 140°F, less than 0°C, or 32°F) or extreme temperature changes. Water- resistance: a watch’s water-resistance cannot be permanently guaranteed. It may notably be affected by the ageing of gaskets or by an accidental shock to the crown. We recommend you have the water resistance of your watch checked once a year by an authorised OMEGA Service Centre.

1 Introduction
Special recommendations
Chronograph push-pieces: do not operate chronograph pushers under water in order to prevent water entering the mechanism. With the exception of the Seamaster Diver 300M and Planet Ocean 600M chronograph models which have functional pushers under water. What are the service intervals? Like any precision instrument, a watch needs regular servicing to ensure that it functions perfectly. We cannot indicate the frequency of such work, since it depends entirely on the model, the climate and the owner’s individual care of the watch. As a general rule, a watch should be serviced every 5 to 8 years, depending on the conditions in which it is used. Who should I contact for a maintenance service or battery replacement? Please contact an approved OMEGA service centre or authorised OMEGA retailer. They are equipped with the tools and apparatus required to carry out the work and the necessary checks in a professional manner. Furthermore, these entities can guarantee that their work is carried out in accordance with OMEGA’s strict quality standards. A battery which has drained should be replaced immediately in order to reduce the risk of leakage and consequent damage to the movement. The type of battery is defined on the guarantee card enclosed with your watch.

1 Introduction
Leather straps
OMEGA recommends that you follow the steps below in order to preserve the condition of your leather strap for as long as possible: ­ avoid contact with water and dampness to prevent discolouration
and deformation. ­ avoid prolonged exposure to sunlight to prevent the colour from
fading. ­ do not forget that leather is permeable! Therefore avoid contact
with greasy substances and cosmetic products. ­ if you have a problem with your leather strap, please contact your
nearest OMEGA retailer!
1 Introduction
Anti-reflective treatment
The anti-reflective treatment on both sides of the sapphire crystal improves the visibility of your watch’s dial. Wear and tear may cause marks to appear. These are considered normal and are therefore not covered by the warranty.
1 Introduction
Screw-down crown
Some watches are fitted with a screw-down crown which must be unscrewed to alter the date and time. After use, push the crown into position 1 then press and screw the crown back down. Failure to screw the crown down will compromise water-resistance.

Chronometer/Master Chronometer
OMEGA watches with a chronometer-certified movement A chronometer is a high- precision watch whose movement has been individually tested, for 15 days in 5 positions and at 3 temperatures, by a neutral official body in accordance with the ISO 3159 (NIHS 95-11) Standard. Each chronometer is unique, and identified by a number engraved on its movement. NIHS: Swiss Watchmaking Industry Standard Master Chronometer OMEGA certified watches In addition to the chronometer movement certification, Master Chronometer watches are individually tested at OMEGA for 10 days before they are delivered to the end customer. Test trials, based on a simulation of wear of the finished watch, aim to ensure the precision, resistance to magnetic fields (1.5 tesla / 15,000 gauss), power reserve and water-resistance of Master Chronometer watches. The process, measurement equipment, and results obtained for each watch are certified by METAS. METAS: Federal Institute of Metrology (Switzerland)

15,000 gauss
Your OMEGA watch is designed to resist a magnetic field of 15,000 gauss. This is an intensity higher than any to which it will be exposed in everyday use (for example, the magnet in a handbag clasp may attain 2,000 gauss). Not only will your watch not stop in the presence of a magnetic field, it will not even suffer any loss of accuracy after being exposed to such a field.

During decompression phase Unscrewed escape valve
He

OMEGA Seamaster watches equipped with a helium escape valve, also known as a helium release valve, have been developed for professional or amateur divers who practise saturation diving. This type of technical diving is essentially used for under-water work carried out at great depths. Between two interventions, the diver is kept in a hyperbaric chamber at a pressure equivalent to the diving depth. He or she is exposed to a complex gaseous mix containing oxygen, hydrogen and helium, among other gases. This technique allows for very long diving times while reducing the risk of accidental decompression. Once the work is finished, the decompression phase begins, with the diver progressively returned to atmospheric pressure levels in the hyperbaric chamber. During a long stay inside a hyperbaric chamber or under- water station, helium is diffused through all the water-resistant materials and penetrates the interior of the watch. During the decompression phase, the infiltrated helium generates excessive pressure in the watch, which can cause it to deteriorate. The function of the escape valve is to evacuate this high pressure during the decompression phase.

3 Specific sections/general information
Helium escape valve
How to use the helium escape valve Manual helium escape valve: If your watch features a manual helium escape valve, the escape valve must always be screwed-in when diving so as to ensure perfect security against potential water entry. The escape valve must only be unscrewed during the decompression phase (when the diver is returned to atmospheric pressure levels) inside a hyperbaric chamber. NB: Even though the escape valve is unscrewed, the watch remains water resistant to a pressure of 5 bar (50 metres / 167 feet). Nevertheless, it is recommended that you always swim or dive with the escape valve screwed-in.
Variation with position indicator: the escape valve is equipped with a red indicator (A) that is visible in the unscrewed position.

Variation with corrector: the escape valve is equipped with an integrated date corrector. The corrector (B) positioned in the centre of the escape valve is functional when the escape valve is fully screwed-in. Automatic helium escape valve: if your watch possesses an automatic helium escape valve (C), no manipulation is necessary.

Measurement scales
The desired information (tachometer; pulsimeter) is read off between the central seconds hand of the chronograph and the corresponding scale, over a maximum duration of 60 seconds. For the telemeter, it is possible to make use of the minutes counter by adding 20 km to the distance indicated by the central seconds hand for each minute elapsed. Using the tachymetric scale
Example: calculating the speed of a car. Record the time the car takes to cover a distance of 1 kilometre. Read off the tachymetric scale the speed indicated by the central seconds hand. In this case, the car is travelling at 120 km/h.

Reading the chronograph minute counter (Seamaster Diver 300M, ETNZ 2015)
Example: counting down the time before the start of a regatta. 3H counter: The inside timer displays the minutes of the chronograph using the white part of the Regatta needle. The outside timer displays the 5-minute countdown before the start of the regatta. The chronograph is started at the first horn blast, 5 minutes before the start of the regatta, to allow the yachtsman to position his boat closer to the starting line.
