Complete Omega Serial Number Timeline

Omega has used a single unbroken sequential series since its founding in 1848 (as Louis Brandt & Frère) with serial production beginning in 1895. Unlike Rolex, Omega never switched to randomized serials — every Omega made to date can be dated from its serial number.

Location Guide

Where to Find Your Omega Serial Number

Caseback (All Eras)

The serial number is engraved on the caseback of virtually all Omega watches. On screw-back casebacks it appears on the outer surface; on snap-back cases it appears on the inner surface.

Between the Lugs (Vintage)

On pre-1970s Omegas the serial may also be engraved between the lugs at 6 o'clock, requiring bracelet or strap removal. Both locations will match.

The reference number typically appears on the same caseback, often separated from the serial by a dash or line. Modern Omegas may also include the reference on a hang tag or inner bracelet clasp.
