The quality standard for Master Chronometer calibres goes far beyond the COSC certification by which all watches are usually measured. Although COSC remains an integral part of the process, OMEGA has doubled its certification with a standard approved by the Swiss Federal Institute of Metrology (METAS).
METAS is the official authority of the Swiss government in all matters relating to measurements and measuring equipment and procedures. As a totally independent institute, METAS is at the forefront of measurement accuracy in Switzerland and is able to establish exact and impartial criteria for defining what accuracy really is. To be awarded with the title of Master Chronometer, a watch must pass the 8 rigorous tests established by METAS. For more information on METAS certification, click here.
There are 3 categories of tolerances for Master Chronometer watches:
0 to +5 seconds per day for movements with a diameter greater than 26 mm
0 to +6 seconds per day for movements up to 26 mm and over 20 mm in diameter
0 to +7 seconds per day for movements up to 20 mm in diameter
There are 2 categories of tolerances for COSC certified watches :
-4 to +6 seconds per day for movements with a diameter greater than 20 mm
-5 to +8 seconds per day for movements up to 20 mm in diameter
A chronograph is a watch with a permanent time display function and an independent mechanism that can be started, stopped and reset to measure time intervals.
The term "chronometer" refers to a watch whose movement accuracy has been certified according to the international standard ISO3159. This certification is carried out by the Official Swiss Chronometer Testing Institute (COSC).
Mechanical watches are driven by a mechanical movement. There are two types of mechanical watches, those known as automatic, which are wound by the movement of the wrist, and those known as manual, which are wound solely by means of the crown. Quartz watches are powered by a battery.
Buying an OMEGA product
You can find a list of OMEGA boutiques and OMEGA authorised retailers here. If our online shop is available in your country, you can also purchase a range of products through the OMEGA website.
These are the most reliable ways to recognise an authentic OMEGA timepiece: Counterfeit products are often offered on unreliable websites. OMEGA watches purchased from unauthorised sources might be damaged or counterfeited and may not benefit from a warranty. Therefore, you should only buy an OMEGA watch from an OMEGA Boutique or an OMEGA authorised retailer. If available in your country, our online shop is also a secured purchase channel. Authentic OMEGA timepieces are supplied with a warranty card, duly completed with an 8-digit numeric or a 7-digit alphanumeric serial number, the watch reference, the purchase date and the retailer's full name and address. Every authentic OMEGA timepiece has a unique serial number. For watches of the current collection, an OMEGA Boutique or an OMEGA authorised service centre will be able to tell you if your model corresponds to the serial number of the watch. Although this does not guarantee the authenticity of the timepiece, it is an important indication. In fact, OMEGA calibres cannot be replicated. Components such as the Co-Axial escapement wheel are exclusive to the brand. If the wrong movement is found inside a watch, it will prove that it is not an authentic OMEGA. Moreover, if the watch is a certified Master Chronometer, it will not be affected by magnetic fields. By placing a magnet close to the timepiece, you can easily detect if it is authentic or not. A Master Chronometer watch will continue functioning normally, while a fake timepiece will stop ticking. In addition, you have the possibility to order an extract from the archives and apply for a certificate of authenticity. The extract from the archives contains the production date and detailed information on your watch, while the certification provides an expert authentication for the current state of a timepiece.

Using your OMEGA watch
The user manual is provided with the timepiece at the time of purchase. In addition, a digital version and video tutorials are available here.
The time setting is explained in the user manual you received at the time of purchase. In addition, a digital version of the manual and video tutorials are available on our here.
OMEGA watches are designed to last a lifetime if they receive the best care. We recommend that you have the water-resistance checked every year and a full service performed every 5 to 8 years. You can also find on our website tips on how to preserve your watch.
During OMEGA's homologation process, watches are tested to the limit. This includes shock tests to confirm the reliability of each timepiece and to ensure that its accuracy is maintained after a strong impact. All OMEGA timepieces are designed to withstand shocks equivalent to a one meter drop onto a hardwood floor. For a standard 150 g timepiece, this sudden and rapid acceleration represents an equivalent force on the watch head of up to 5,000 G.
Unless your OMEGA watch is equipped with a Master Co-Axial Chronometer movement, which is capable of withstanding magnetic fields of up to 15,000 gauss, we recommend that you avoid exposure to high magnetic fields, such as those produced by loudspeakers, refrigerators, some handbag or tablet case clasps, etc.
Our watches are designed to withstand active sports such as golf and skiing. The optimum operating conditions for your timepiece are between 0°C (or 32°F) and 60°C (or 140°F). Use outside this temperature range may affect the performance of your watch. In addition, we recommend that you avoid exposing your timepiece to wide temperature variations.
All current OMEGA watches are water resistant to the depth defined by the model specifications, provided that the water resistant components are intact. This means that an OMEGA watch that is water resistant to 30 metres can be worn for swimming (with vigorous movement) at depths of up to 30 metres underwater for extended periods without restriction. We would like to emphasize that the water resistance of a watch is ensured by gaskets placed between the crown, the pushers, the crystal, and the watch case. These gaskets deteriorate over time under the influence of external factors such as temperature variations, pollution or chemicals and must be regularly replaced to guarantee the water resistance of the watch. In addition, heavy impacts on the crown, pushers or helium valve are known to affect the water resistance and should be avoided. The following tips will help you keep your OMEGA watch water resistant:
Always rinse your watch with tap water after swimming in salt water
If your watch is equipped with a screw-in crown, always screw it in after handling it
If your watch is equipped with an unscrewed crown, push it back against the case in the wearing position to prevent moisture from entering the case
Avoid operating the chronograph pushers under water to prevent infiltration into the movement. Exceptions: the Seamaster 300M and 600M chronographs are equipped with pushers that can be operated under water
Instructions for winding your watch can be found in the user manual. A digital version of the manual and video tutorials are available here.
The use of a watch winder can help you to ensure that the power reserve is within the calibre's specifications. This applies even if you don't wear your OMEGA timepiece daily or if your wrist movement is insufficient. We recommend that you use a watch winder from the OMEGA leather goods collection. You can find more information about our leather goods here. This document will help you to set the watch winder to ensure a power reserve according to the calibre specifications.
The winding of a watch with an automatic mechanical calibre depends on the movement of the wrist. If your watch has not been worn for several days or if your wrist movement is insufficient to guarantee automatic winding, the power reserve of your watch will be less than its maximum capacity. In this case, it is necessary to wind it manually, following the instructions given in the user manual.
Caring for your OMEGA
Whether you have a current or a vintage watch, OMEGA authorised service centres offer efficient and personalized solutions. Contact details of OMEGA authorised service centres can be found here.
Recommended public prices by watch type are available here.
The detailed steps of the complete service are available here.
We offer a twenty-four (24) month warranty on each service performed by an OMEGA authorised service centre. In the event of a fault covered by the service warranty, we will, at our discretion and without cost, repair or replace any spare parts and/or rectify any faults as identified as such by our customer service. All other rights resulting from the faulty execution of our services are expressly excluded. This warranty does not cover normal wear and tear or damage caused by accidents, lack of care or negligence. This warranty is rendered void if the work is carried out on the watch by persons who are not authorised to do so by OMEGA SA.
The service frequency depends on the use of the watch and the environment in which it is worn. The water resistance can, for example, be affected by the aging of the gaskets or by an accidental shock. Therefore, we recommend that you have the water resistance checked once a year and a complete service performed every 5 to 8 years. Contact details of OMEGA authorised service centres are available here.
The life of a battery depends on the type of the watch and the use of its functions. Most of today's OMEGA quartz movements are equipped with an end-of-life (EOL) indication system. When the battery is nearly exhausted, the second hand will move in 4-second jumps. Although the watch will continue to function for a few days, we recommend that you have the battery replaced by an OMEGA authorised service centre without delay to reduce the risk of leakage which could damage the movement.
Find information about the brand and our product
All watches purchased from OMEGA authorised retailers are authentic. They are supplied with a warranty card, which includes the 8-digit numeric or 7-digit alphanumeric serial number, the watch reference, the date of purchase and the full name and address of the retailer. An authentic OMEGA watch has its own serial number. For pieces of the current collection, your nearest OMEGA Boutique or authorised service centre will be able to tell you whether your model matches the serial number on the watch. Although this does not guarantee the authenticity of the watch, it is an important indication. In fact, OMEGA calibres cannot be reproduced. Some components such as the Co-Axial escapement wheel are exclusive to the brand. If the timepiece is equipped with a different movement, it will prove that it is not an authentic OMEGA watch.
Moreover, if the watch is Master Chronometer certified, it will not be affected by magnetic fields. By placing a magnet near the watch, it is easy to detect whether it is authentic or not. A Master Chronometer watch will continue to function normally while a counterfeit will stop functioning.
For watches older than 30 years, we offer a certification service. You can find information about the certificate of authenticity here.
The first step is to identify the case and movement number. If you need help finding this information, we recommend that you visit an OMEGA authorised service centre. Once you have these numbers, go to the vintage section of our website and enter your case number in the search field.
If no information is available in the vintage section, we recommend that you order an extract from the archives. This document indicates the date of production of the timepiece and contains detailed information about the condition of the watch after its production. It is available for most OMEGA watches over 10 years old and costs CHF 120 (excluding VAT) per extract or the equivalent in your local currency.
The information about your watch may no longer be available. In this case, we will refund the full amount paid. On the other hand, according to our terms of sale, following the analysis of the data provided at the time of your request, we will cancel your order without refund in the following situations (non-exhaustive list):
The watch movement number and/or watch case number is wrong
The watch movement number and/or the watch case number is incomplete
The watch movement number does not match the case number or watch reference number
The description of the watch does not correspond to the information in our archives
The pictures of the watch do not match the information in our archives
Significant modifications have been made to the watch outside our workshops
The watch is recorded in our records as "stolen" or inauthentic.
We would also like to point out that the extract from the archives is not a certificate of authenticity and does not guarantee the authenticity of a watch or its components.
The value of a pre-owned OMEGA watch may vary depending on its functional and aesthetic condition and the supply and demand for similar watches on the market. Prices also depend on factors specific to each country.
Watch assessment is a specialized field of expertise in which we are not active and therefore we cannot provide any information on this subject.
We recommend that you have your timepiece examined by an auction house or antique dealer of your choice.
Below is a non-exhaustive list of some major auction houses:
This information can be found on the warranty card that is given to you at the time of purchase. The serial number is also engraved on the back of our current watches, or on one of the lugs. For vintage watches, this information is usually engraved on the inside of the caseback and on the movement. OMEGA authorised service centres are available to assist you in retrieving this information.

All the watches worn on the Moon were part of the Speedmaster collection and were equipped with the legendary calibre 321.
During the Apollo 11, 12, 14, 15, 16 and 17 lunar missions, the astronauts wore Speedmaster model references ST 105.012 and ST 145.012.
Captain Eugene "Gene" Cernan also wore a Speedmaster ST 105.003 during the Apollo 17 mission.
The Speedmaster is still part of our current collection and has since become an icon in the watchmaking world.
At OMEGA we use a unique number to identify each watch, called a Long Product Identification Code, or PIC, which consists of fourteen numbers.
For example, the De Ville Ladymatic OMEGA CO-AXIAL 34 MM has the following PIC or Long Product Identification code: 425(A).65(B).34(C).20(D).63(E).001(F).
Each of these numbered codes is divided into six lettered groups, A through to F, which refer to the specific details of the timepiece.
For instance, the fourteen numbers of the watch we've just mentioned breaks down as follows.
The first three numbers of the code (Group A) refer to the OMEGA line or family of watches. (425= De Ville Ladymatic)
The next two numbers of the code (Group B) refer to the material of the watch head and bracelet or strap. (65 = gold + other material paved for the watch head and assorted metal for the bracelet)
The following two numbers (Group C) reference the diameter and size of the watch. (34 = 34mm)
The eighth and ninth number of the code (Group D) reference the movement and complication, or the calibre that powers the watch. (20 = Mechanical with Co-Axial)
The following two numbers (Group E) reference the color and the material of the dial. (63 = brown + precious stones)
The final three numbers of the fourteen-number code (Group F) refer to the specific sequence number of the watch. (001= first in the sequence).
