Rolex Serial Numbers: How to Check Yours

If you own a Rolex watch, it’s likely that you’ve thought about how old it is and how much it might be worth today. While checking your Rolex’s serial number can’t tell you the exact value of your Rolex — that depends on several factors including current market conditions and rarity — it’s still useful information, and can give you an idea of its age and production date.

The combination of your serial number and model number can also help determine if your Rolex is genuine or not. When it comes to counterfeit Rolex watches you’ll find that either the watch does not have a serial number engraved on it, or the serial number present doesn’t match the design of the watch.

In this article, we’ll explain how to check the serial number on your Rolex watch so that you can find out exactly when it was made.

A Bit of History about Rolex Serial Numbers

Rolex serial numbers are unique and can be used to track the watch’s history. They are not encrypted, sequential, or standardized in the present day; each one is different and tells an interesting story about its owner. If you have a Rolex watch, it’s important to know how to check the serial number so that you can keep track of your timepiece’s history.

Rolex has been engraving their luxury timepieces with unique serial numbers since the 1920s specifically to document in what year that particular watch was manufactured. As you can see in the table below, the specific type of serial number coincides with a year of production, making it a quick and simple process to date your particular watch once you have the serial number.

Having serial numbers to date your watch is especially helpful because, while Rolex makes changes to their designs over time, they’re subtle enough that it can be hard to distinguish an older model from a more modern one.

Until 2010, there was a system that is delineated in the table below. Between 1926 and 1987 Rolex used sequential serial numbers that are easy to look up. Between mid-1987 and late 2009, they used a simple date code to help with the date of production. A letter at the beginning of the number would tell you what year, instantly.

The historic 1954 reset

In 1954, Rolex reached a historic 1,000,000 watches produced with serial numbers. They decided not to simply continue counting, but reset the serial numbers to 100,000. This created some confusion when it came to translating the serial numbers between the mid-1950s and the beginning of the 1960s.

To clear up the confusion, Rolex put a date code on the inside of many of their case backs. While this clears up the confusion, it does make it difficult for the everyday person to verify the production date of their watch if it was manufactured during this period. Case backs should only be removed by a Rolex-licensed servicer.

How to check the serial number of your Rolex watch

To check the serial number of your Rolex watch, you need to know where it’s located. The location of the serial number on your watch is also dependent on its production date. But in the end that only narrows down your search in the first place, depending on where you find the serial number.

Finding Your Serial Number

Watches made before 2007 will have the serial number engraved on the case between the bottom lugs. The lugs are where the band connects to the case. In order to find this serial number, you’ll have to remove the band of your watch.

For some models between 2006 and 2007, you’ll find the serial number engraved on the dial rehaut (inside metal ring). This is the inner bezel, and you’ll find it around 6 o’clock. Some models during this time will also have it engraved on the case between the bottom lugs as well. You’ll have to look carefully for the serial number on the dial rehaut. Looking carefully at the 6 o’clock position, you should be able to see it through the crystal.

Watches made after 2008 gradually lost the engraving between the bottom lugs as this was easier to replicate. You’ll only find it on the inner rehaut. If you have the paperwork for your watch, you’ll find the serial number there as well. It’s a good idea to match the engraving on the watch to the one on the paperwork when you’re buying the watch.

To sum up:

Pre-2005 Rolex: the number is engraved between the lower lugs (near 6 o’clock)

2005-2008 Rolex: the serial number is engraved on the case between the lugs and on the inner rehaut

Post 2008 Rolex: it’s engraved only on the inner rehaut

Finding Your Watch’s Production Year

Using the table below, you should be able to determine the year of production after you’ve found the serial number on your watch.

Earlier watches have simply sequential numbers. If there’s a letter at the beginning of your serial number look between the years of 1987 and 2010. Anything after 2010 is a random and mixed series.

How to find the model or reference number of your Rolex watch

Now, hidden on the case between the upper lugs at 12 o’clock you’ll find your model or reference number. Rolex engraves or at least assigns every watch a 4 to 6 digit model number. Much like when finding your serial number, you’ll need to take off the bracelet or strap in order to see this engraving.

This engraving can be a little confusing if you don’t know what you’re looking at. Rolex uses a reference number system that gives you a lot of information about the model, the bezel, and the material the watch is made of.

The first 2 to 4 digits are what indicate the model of the watch. The second to last digit indicates the type of bezel on the watch while the very last digit indicates the material of the watch. Any letters found at the end of the sequence will indicate special additions like colors and faceted diamonds. For instance, LV would stand for lunette vert, and looking at the chart that means green bezel.

You can use the three charts below to translate your watch’s reference number.

How to find the production age of your Rolex bracelet and clasp

Your bracelet and clasp will also be engraved with a code that tells you the month and year that they were manufactured.

Inside the clasp hinge you’ll find the clasp code on many models. There will be 1 or 2 letters preceding a number. The letters tell you the year while the numbers will indicate which month it was made.

A clasp engraved with an S means it was replaced during a service visit.

Frequently Asked Questions about Rolex Serial Numbers

What if my Rolex’s serial number does not match the paperwork?

If your Rolex’s serial number does not match the paperwork, chances are that it is not genuine. But there’s also the possibility that the paperwork got mixed up with another watch. If you’re worried about its authenticity, get your watch authenticated at an authorized dealer. Better yet, when buying a pre-owned watch, always buy the seller. Only purchase your watch from reputable dealers who can provide an authenticity guarantee, and who have solid presence and reviews online.

Can the serial number on my Rolex tell me if it’s fake?

It’s not dependable, but you can do a quick Google search of the serial number for more information. Serial numbers and their meaning aren’t something that Rolex is open about. More than likely searching your serial number will produce nothing. In the instance where you get some hits about your serial number then it’s time to dig a little deeper.

If the watch is genuine then you may get some information on the previous owners or sellers. The other instance where your serial number would pop up some results is through the counterfeit industry. Many forgeries have been known to carry the same serial numbers and these are often reported to not just the authorities, but forums for collectors to help others avoid the same fate.

The serial number, model number, and even the bracelet number of your Rolex watch may be minute details, but they provide a lot of information about your timepiece that can come in handy when trying to authenticate and appraise it.
