An OMEGA serial number can help you estimate when your watch was manufactured. Use our OMEGA serial number lookup charts below to find the approximate production year of your watch, including vintage Seamaster, Speedmaster, Constellation, and De Ville models.

Most OMEGA serial numbers contain seven or eight digits and can be found on the movement, caseback, lugs, or original paperwork, depending on the model and age. Because OMEGA production records and numbering systems vary, these charts provide estimates rather than exact manufacturing dates.

Not sure where to find your number? We'll show you where to look, how to check it against the correct chart, and how serial numbers differ from OMEGA reference numbers.

Omega Serial Numbers

The easiest place to find an Omega serial number is on the corresponding paperwork for the watch such as the warranty card, chronometer certificate, certification of authenticity, or official service records. However, having the original paperwork is not always feasible - particularly in regards to vintage Omega watches.  In those instances, an OMEGA serial number lookup isn't as difficult as you might think. You can find the serial number on the actual Omega watch itself.

Each Omega watch has a seven-digit or eight-digit serial number etched somewhere on it. For most Omega watches, the watch’s serial number is in fact the movement serial number, which is etched on a bridge of the internal movement. In more recent decades (by most estimates, the early 1990s), Omega also began placing the movement serial number on the exterior of the watch - sometimes on the back of the lugs and sometimes on the outside of the caseback.

However, there are some important discrepancies to note here. First, some Omega watches do not have a movement serial number (for instance some non-COSC movements and some ETA-based movements) but they will have a serial number somewhere else on the watch such as the interior caseback, exterior caseback, or lugs. It’s also been reported that Omega does not always place the serial numbers in the same place, which can create an additional level of confusion for collectors that do not have experience with the brand.

Therefore, depending on the specific model and year of production, an Omega serial number can be found on:

• The movement
• The interior caseback
• The exterior caseback
• The back of the lugs

If the serial number is not on the exterior of the watch (which will generally be the case on vintage and older Omega watches), the caseback will have to be removed in order to view the serial number engraving, which will be located either on the movement itself or on the inside of the caseback.

Yet another important thing to note is that because Omega serial numbers are typically movement serial numbers, the sequence of serial numbers should be taken with a grain of salt. Movement parts could have come together much earlier than a complete watch, so it is entirely feasible that a later model could have a lower serial number than an earlier model. Furthermore, the below charts are estimations, therefore there is the possibility that certain production dates could be off by as much as a few years.

Finally and perhaps most importantly, the Omega Speedmaster - the brand's most famous collection of watches and the model best known for being the first watch worn on the moon - follows a different Omega serial number system. So, if you're looking for the serial number of an Omega Speedmaster, it's crucial to make sure you're using the correct chart.

*Again, it should be reiterated that these Omega Serial Number charts are approximations and cannot always guarantee the exact year of manufacturing for all Omega models.

Omega Reference Numbers

Over the years, Omega has used a variety of different reference number systems, which can sometimes make it a bit tricky to understand exactly what they mean.

• First System (before 1962): XY 1234
• MAPICS System (1962 – 2007): XY.123.456 & XY.123.4567 (from 1970)
• PIC System (1988 – 2007): XXXX.YY.ZZ
• PIC14 System (from 2007): AAA.BB.CC.DD.EE.FFF

Omega Codes for 7-Digit References

From 1970 until 1988, Omega used an alphanumeric code with letters and seven digits for reference numbers. An example of the Omega 7-digit reference number layout would be: BB.145.XXXX.

• Letters denote materials
• First three digits denote watch characteristics
• Last four digits (XXX) denote case, dial, and bracelet styles.

Omega Product Identification Codes (PIC)

When it comes to Omega watch reference/model numbers, it will be the PIC number that you will want to look for to learn more information about the watch. PIC stands for Product Identification Code. From 1988 until 2007, Omega used an 8-digit PIC System. Then in 2007, Omega switched over to a 14-digit PIC System, which the brand continues to use for the watches that it manufactures today.

Where Can I Find Omega Reference Numbers?

While vintage Omega watches typically include the reference/model number stamped inside the caseback (meaning that you'll have to open the watch to see it), modern Omega watches do not. To find the complete PIC reference number of an Omega watch, you'll have to consult the accompanying paperwork.
