Rolex serial numbers
Sminto is not affiliated with, endorsed by or an authorised service of Rolex. This page does not authenticate watches.
Numeric serials to 1987 date the case to within a year or two, with charts that disagree; a letter prefix dates 1987 to 2010; the random serials since 2010 carry no date, and the page says so.
Where to find the serial
Between the lugs at 6 o'clock, under the bracelet end link, on watches made before about 2008; engraved on the rehaut (the inner bezel ring) at 6 o'clock since then; on the warranty card.
Where to find the reference
Between the lugs at 12 o'clock, under the bracelet; on the warranty card; on the rehaut since the mid-2000s on some models.
What this page can and cannot say
It reads the serial against the format rules Rolex has used and says which era it fits. Numeric serials to 1987 date the case to within a year or two, with charts that disagree; a letter prefix dates 1987 to 2010; the random serials since 2010 carry no date, and the page says so. With a reference it says whether the serial's era and the reference's production window fit each other.
It does not say whether a watch is real or fake, it does not ask the brand anything, and no lost-or-stolen check is performed here. Years are estimates from published tables that the brand does not publish or endorse; where tables disagree, the page shows both.
No reviewed table for Rolex yet, so the check does not run for this brand. Rows go live only with a source and a reviewer; the Rolex serial number table shows what is live.
