How to Sell an Omega Watch in 2025

Omega is one of the most prolific Swiss luxury watch brands, with an immensely diverse collection of watches on offer. Models like the Speedmaster, Seamaster, and Constellation are each offered in countless varities. So it can be difficult to know how much your specific example is worth, but fortunately Omega is one of the most liquid watch brands on the resale market this side of Rolex. If you’re wondering how to sell your Omega watch, read on.

For a comprehensive overview of the overall selling process, you can dive into our guide on how to sell a luxury watch. However, since every watch brand is slightly different, we’ve compiled some handy Omega-specific tips below.

Identify the Omega Reference Number

Regardless of the specific brand, the first step when selling a watch is always the same: identify the reference number. This string of numbers represents the specific model you have, and it’s key to understanding how much it’s potentially worth. Reference numbers of Omega watches are quite long, but they’re especially useful to know because they include information about the model family, material, dial, and bracelet.

Omega Reference Numbers Explained

Omega has used various reference numbering systems over the years. The two most modern systems are the following:

• 8-Digit Product Identification Code (PIC) System (1988 – 2007): XXXX.YY.ZZ
• 14-Digit Product Identification Code System (from 2007): AAA.BB.CC.DD.EE.FFF

Using the Omega Speedmaster Moonwatch reference 310.30.42.50.01.001 as an example:

• Group A refers to the Omega family of watches. E.g. 310 = Speedmaster
• Group B refers to the case and bracelet material of the watch. E.g. 30 = steel and another material for the case + assorted metal for the bracelet (steel in this instance)
• Group C refers to the case size. E.g. 42 = 42mm
• Group D refers to movement type. E.g. 50 = mechanical chronograph
• Group E refers to dial color and material. E.g. 01 = black
• Group F refers to the specific sequence number of the watch. E.g. 001 = first in the sequence

While older Omega watches typically had the reference number engraved on the inside of the caseback, modern Omega watches do not have reference numbers on them. Therefore, if you no longer have any of the official paperwork of the watch, you’ll have to do some research to find out the exact reference number of the Omega watch you want to sell.

Here are some things you can do to find out your Omega’s reference number without any accompanying papers:

1. Research the main Omega collections on the company’s website to pinpoint your model
2. Google some of your watch’s details (model, material, dial color, bracelet type) and see if anything similar comes up
3. Take a photo of the Omega you want to sell and do a Google image search
4. Post a photo of your watch on a forum (such as Omega Forums or r/Watches on Reddit) and see if a member can help you ID the watch
5. Take it to an authorized Omega dealer to request the information
6. Order an Omega Extract from the Archives (more on that later)

Omega Serial Numbers

As is customary with high-end timepieces, each Omega watch has a unique serial number, which includes either 7 or 8 digits.

Depending on the model, the Omega serial number (sometimes referred to as the case number) can be found on the movement, the exterior caseback, the interior caseback, or on the back of the lugs. These numbers are issued sequentially, which can help determine an approximate manufacturing year. There are a number of Omega serial number charts online that you can cross reference. However, keep in mind that these aren’t official tables made by Omega but rather, information put together by Omega enthusiasts and collectors. So, take the information with a grain of salt.

It’s worth mentioning that the movement number and the serial number are sometimes the same. Another important point to be aware of is that Omega uses a different serial number system for the Speedmaster, so if you’re trying to calculate when your Speedmaster was made, make sure you’re looking at the correct serial number chart.

Although it’s not a bad idea to blur your watch’s serial number in pictures, potential buyers may eventually want to know what it is to affirm that the Omega watch you’re selling is authentic.

Do I Need the Paperwork When I Sell My Omega Watch?

Having the box and papers of any watch you’re selling will always increase the value of your set. In some cases, a complete set can sell for 10 to 20% more than naked watches. Therefore, if you have any of the original paperwork (warranty cards, receipts, service records, and instruction booklets), packaging (boxes, cushions, and bags), and accessories (additional straps or tools) of the Omega watch you want to sell somewhere in your possession, then take the time to find them all.

Omega also offers an Extract from the Archives service, which provides official documentation of your specific watch. Bear in mind that the brand clearly states that an extract from its archives is not the same as a certificate of authenticity. Depending on your region, you can order an Omega Extract from the Archives for CHF 120 directly from the company’s website. However, U.S.-based clients cannot order one online but they can request one from an Omega authorized dealer for $150.

You can also order a Certificate of Authenticity from Omega. However, the watch has to be at least 30 years old and you’ll have to send your timepiece to the company for inspection. The process costs CHF 800 and can take up to two months. Depending on the value and rarity of the Omega watch you want to sell, this may not be worth the time or cost.

How to Know the Market Value When I Sell My Omega?

Once you know the reference number and the age of the watch, you can begin to assess market value. Websites like watchcharts.com and watchrecon.com are useful; just search for your reference number and see what’s out there. Even Ebay completed listings can be quite insightful. But keep in mind most well-known professional sellers can price their watches about 10% higher than random private sellers can expect to get. Selling your watch on a platform like Ebay or Chrono24 can work out fine, but expect to lose another 10% to shipping and fees.

Should I Service My Omega Watch Before Selling It?

The prices for servicing an Omega watch can be costly, generally ranging from $500 to well over $1,000. So, is it worth servicing your Omega watch before reselling it? The quick answer is no. Barring complete disrepair, we typically do not recommend servicing any watch before selling it for a few reasons.

First, vintage watches will always be valued more if they have their original factory components. Servicing an older Omega watch may mean that some of those original parts will be replaced.

Second, it’s unlikely that you’ll be able to cover that additional cost with the final selling price of your watch.

And finally, if you sell your Omega directly to a grey market dealer, they’ll take care of any maintenance requirements before selling it to someone else.
