How to find, read, and date your Rolex
A Rolex serial number is a unique code engraved on the watch case that identifies the individual watch and, for models made before roughly 2010, indicates the year it was produced. You can estimate a vintage or pre-owned Rolex’s age by matching its serial against a production chart. Watches made from about 2010 onward use randomized serials that no longer reveal a year.
Quick answer
To look up a Rolex serial number, find it on the 6 o’clock side of the case: between the lugs on watches made before about 2005, or engraved on the rehaut, the inner ring under the crystal, on later models. Match its first letter or its number range to the chart below, or enter it in the lookup tool. Serials issued from about 2010 onward are random and cannot be dated this way.
That last point is where most serial lookups go wrong, so this guide covers both how to read an older serial and why a newer one will not date the same way.
Where is the serial number on a Rolex?
The location changed over the years, so where you look depends on how old the watch is. On every Rolex the serial sits on the 6 o’clock side of the case.
Before 2005: the serial is engraved on the outside of the case, between the lugs at the 6 o’clock position. You have to remove the bracelet to see it, which is why owners of older models often have never laid eyes on their own serial.
2005 to 2008: during this transition period Rolex engraved the serial in two places, both between the lugs and on the rehaut, the inner metal ring between the dial and the crystal.
2008 onward: the serial moved to the rehaut only, etched in tiny characters on the 6 o’clock side. You can read it through the crystal, usually with a loupe and good light, without removing the bracelet.
Serial and reference locations
Every Rolex marking sits on the 6 or 12 o’clock side of the case
Serial number vs reference number
A Rolex carries two important engravings, and they do different jobs.
The serial number is unique to your individual watch. It sits between the lugs at 6 o’clock (or on the rehaut on newer pieces) and, on older watches, points to the production year.
The reference number, also called the model number, identifies the model itself rather than the single watch. It is engraved between the lugs at the 12 o’clock position. Every Submariner of a given generation shares the same reference; each one has its own serial. The reference is what tells you the model, the bezel, the bracelet, and the general era, so it is often more useful than the serial when you are identifying a modern Rolex.
Together they answer two questions: the reference tells you what the watch is, and the serial tells you which one it is.
How to read a Rolex reference number
On most five-digit references, the first digits identify the model family and the last digit identifies the case metal. The material codes below apply to five-digit references made before about 2000. Six-digit references follow a similar pattern but added codes, so confirm a modern watch against the model before relying on the last digit.
| Last digit | Case material |
|---|---|
| 0 | Stainless steel |
| 1 | Yellow gold filled |
| 2 | White gold filled |
| 3 | Steel and yellow gold |
| 4 | Steel and 18k white gold |
| 5 | Gold shell |
| 6 | Platinum |
| 7 | 14k yellow gold |
| 8 | 18k yellow gold |
| 9 | 18k white gold |
Two examples from our own inventory: a Datejust 16234 ends in 4, steel with an 18k white gold bezel, and a Datejust 16220 ends in 0, all stainless steel. Read together, the reference and the serial tell you what the watch is and roughly when it was made.

Published Rolex serial charts disagree with each other by up to a year at many of these breakpoints, because Rolex has never released an official list and numbers were not always issued in strict order. Treat any year from a chart as an estimate, and use the guarantee card or service papers when you need a firm date.
Treat these as close estimates rather than exact cutoffs. Rolex did not publish official production dates, so every serial chart is built from observed watches and the ranges can drift by a few months around each boundary.
Why you cannot date a modern Rolex by serial number
Starting in 2010, Rolex moved to randomized serial numbers. The digits and letters no longer run in sequence and no longer encode a production year. This was a deliberate anti-counterfeiting step, and it means a serial-by-year chart simply does not work on a watch made in the last fifteen years or so.
If your Rolex is modern, here is how to date it instead:
The warranty or guarantee card
Rolex cards carry a purchase date. Cards issued from 2007 onward also show the reference and serial, and modern ones include a security feature that dealers can verify.
The reference number
The model reference narrows the watch to a production era even when the serial cannot.
Original purchase records
A receipt or service history often pins down the year more reliably than any chart. A jeweler or authorized service center can also open the case back and read internal markings that help confirm the period.
Can a serial number tell if a Rolex is real?
No. A serial number on its own cannot confirm that a Rolex is authentic, and there is no public Rolex database where you can type in a serial and verify a watch. Rolex does not offer a consumer lookup service.
There are two reasons a serial alone is not proof. Counterfeiters copy real serial numbers onto fake watches, so a valid-looking number can appear on a replica. And a genuine number engraved crookedly, too deeply, or with the wrong finish can actually be a sign of a fake, because Rolex engraving is famously crisp and precise.
Authenticating a Rolex means looking at the whole watch: the movement, the dial printing, the cyclops magnification, the weight, the bracelet, the engraving quality, and the paperwork, ideally in the hands of someone who examines these watches regularly. If that is where you are headed, our guides on how to spot a fake Rolex and how to tell if a Rolex is real walk through the specific tells.
How Dom’s dates and authenticates a pre-owned Rolex
Every pre-owned Rolex we handle is checked in person. We read the serial and reference, cross-reference the production era, examine the movement and dial under magnification, and review whatever paperwork comes with the watch. Dating is only the first step; the fuller process of confirming a watch is genuine and correctly described is covered in how Dom’s sources authentic pre-owned luxury watches.
Frequently asked questions
Where is the serial number on a Rolex?
On the 6 o’clock side of the case. Watches made before 2005 have it engraved between the lugs, under the bracelet. Watches from about 2008 onward have it on the rehaut, the inner ring between the dial and crystal, readable through the crystal.
How do I check what year my Rolex is?
Find the serial number and match it to a Rolex serial-by-year chart, like the one above. This works for watches made before roughly 2010. For newer watches, use the guarantee card, the reference number, and your purchase records instead.
Can I look up a Rolex by serial number online?
There is no official public Rolex database for serial lookups. Charts like this one estimate the production year for pre-2010 watches, but Rolex itself does not provide a consumer verification tool.
Does the serial number prove my Rolex is real?
No. Counterfeits can carry copied serials, and a genuine-looking number is not enough on its own. Authentication requires examining the full watch and its paperwork, ideally by a specialist.
What is the difference between a Rolex serial number and a reference number?
The serial number is unique to your individual watch and sits at 6 o’clock. The reference, or model, number identifies the model and sits at 12 o’clock between the lugs.
Why doesn’t the serial number chart work on my newer Rolex?
Because Rolex switched to random serial numbers around 2010. Newer serials do not run in sequence and do not encode a production year, so a chart cannot date them.
How accurate is a Rolex serial number chart?
A chart gives an estimate, usually within a year. Rolex has never published an official serial list, so every chart is compiled from observed watches and published charts differ at many breakpoints. Serials were also not always issued in strict order, so a watch can carry a serial from the year before or after it was cased. For a firm date, use the guarantee card or service records.
How do I look up a Rolex serial number made after 2010?
You cannot date it from the serial. Since about 2010 Rolex has used random eight-character serials that carry no production year. To date a modern Rolex, use the date on the warranty card, the purchase receipt or service papers, and the reference number, which narrows the model generation. A Rolex service center can also confirm details when the watch is in for service.
