Rolex Reference and Serial Number: Where to Find Them

Every Rolex carries two numbers. The reference number (Rolex calls it the model number) says which watch it is: the model, the size, the bezel and the metal. The serial number is unique to your individual watch. A buyer needs the reference to value the watch and the serial to match it to its papers. You can find both in a couple of minutes without opening anything.

The quickest way: the warranty card

If you have the Rolex warranty card (the plastic guarantee card that came with the watch), both numbers are printed on it: the model number is the reference, and the serial number is next to it, along with the date of purchase and the retailer. Older watches came with a paper guarantee certificate instead of a card; Rolex moved from paper to a plastic card in the 2000s. The numbers on the card or certificate should match the watch.

The purchase bill usually shows the reference as well. A Rolex service card, if the watch has been serviced by Rolex, shows the serial number.

Where the numbers are on the watch

On the inner bezel ring (newer watches)

On newer Rolex watches the serial number is engraved on the inner bezel ring, the polished ring between the dial and the crystal that repeats the word ROLEX. Look at the 6 o'clock position through the crystal, under good light. Rolex introduced this engraving in stages from around 2005, and it was on all models by around 2010.

Between the lugs (all watches for the reference, older watches for the serial)

The reference number is engraved on the side of the case between the lugs at 12 o'clock, hidden behind the end of the bracelet. On older watches the serial number is in the same place on the opposite side, between the lugs at 6 o'clock. To see either one the bracelet has to be detached from the case on that side.

You do not need to do that yourself to sell. A spring-bar tool slipping is the commonest way a case gets scratched. If you have no card and cannot read the inner ring, tell us what you can see - model name, case size, bezel and dial colour - and send a clear photo of the dial.

How to read a reference number

A modern reference has six digits, sometimes followed by letters. The first digits identify the model family and generation; the last digit is the metal; the letters describe the bezel.

So 126610LV is a Submariner Date (1266) in steel (0) with a green bezel (LV), and 126334 is a Datejust 41 in steel with a white gold bezel (4). The digits after a dash on some paperwork, such as 126334-0027, are a catalogue code for the dial and bracelet combination.

What the serial number does and does not tell you

On older watches the serial number followed a sequence, so it gave a rough production period. Since around 2010 Rolex has used random serial numbers, which say nothing about the year. For a newer watch the reliable date is the purchase date on the warranty card. Rolex watches sold from 1 July 2015 carry a five-year international guarantee from that date.

References for the Rolex models we buy

Each model page lists its references in full. This is the short version.

What to keep ready before you sell

• The reference number, from the card or the watch.
• The warranty card or paper certificate, the original box and the purchase bill, if you have them. None is required, but in our price form each one adds to the quote.
• Any Rolex service paperwork, and roughly when the watch was last serviced. Rolex itself recommends a service about every ten years, depending on the model and how it is worn.
• All the bracelet links, including the spare ones removed when the watch was sized.
• A note of anything that has been replaced or is not original: dial, hands, bezel, crystal, bracelet, or diamonds set after purchase.
• A government photo ID. We check one at every purchase.

Selling your Rolex to Sell Your Gadget

1. Tell us about the watch. Four questions: is it in working order, do you have the box, bill and warranty card, how long ago was it bought, and what condition is it in. Then the watch details: reference number, service history, scratches and bracelet links.
2. Verify your mobile number and get the offer. The quote appears on screen. Where the site shows "Price on request", our team calls you with the offer instead.
3. Book a free doorstep pickup. You choose the address, date and time slot.
4. The watch is checked in front of you. If something differs from what you described, you are told the reason and the revised price, and you can decline and keep your Rolex.
5. You are paid at the pickup, after you approve the final price and hand over the watch, by UPI, bank transfer or cash, whichever our representative offers at the time (above Rs 10,000 we prefer bank transfer or UPI). A government photo ID is checked at every purchase.

A Rs 250 visit charge applies only if you book a pickup and then decide on your own not to hand over the watch when our representative arrives. It is not charged if you turn down the final inspected price. Details are in section 4 of the terms.
