Serial numbers
- ? – ? (2021–?) — The Omega 220 series carries no serial number on the exterior of the case; the production year can be derived from the internal movement number via Omega customer service.
With the 220 series, Omega broke with a detail in 2021 that still preoccupies collectors: the teak pattern now runs horizontally rather than vertically. On the 220.52.41.21.03.001, this change arrives in Sedna Gold — Omega's proprietary rose gold alloy, 18 karat with an elevated palladium content. The result is a blue dial with pronounced visual depth, a date window at 3 o'clock, and nothing else. No crown guard, a symmetrical case, exhibition caseback.
## What the Calibre 8901 Has to Deliver Inside a Gold Case
The calibre 8901 is Co-Axial, METAS-certified, and remains accurate in magnetic fields up to 15,000 gauss — something no base ETA calibre can claim. Omega specifies an accuracy of 0 to +5 seconds per day. Inside a 41 mm solid gold case, that's no foregone conclusion: gold conducts heat differently than steel, demanding greater thermal stability from the movement within its shell. That Omega fits the 8901 here rather than the 8917 is not a cost decision — it's a deliberate variant separation.
## Why the Sibling References With Small Seconds Carry Different Names on the Omega Website
Alongside the .03.001, Omega launched two sisters: 220.52.41.21.03.002 and 220.52.41.21.02.001, both featuring a small seconds hand and calibre 8917. The .03.001 is the date-only variant — listed on the Omega US website without "small-seconds" in the URL, its dial kept deliberately uncluttered. On the secondary market, this solid-gold Aqua Terra speaks to a narrow audience, which makes price swings — in either direction — considerably more volatile than with the steel version in the same reference family.
Brand profile: Omega
Omega is the second most counterfeited Swiss watch brand. The Speedmaster and Seamaster are especially targeted. Pay close attention to movement details (Co-Axial) and dial textures.
- Speedmaster: The chronograph reset hand must snap back precisely to 12 o'clock — fakes stop 1–3 seconds off or wobble
- Speedmaster (Hesalite): The Omega logo is micro-laser-etched on the UNDERSIDE of the Hesalite crystal — only visible at a specific angle and in the right light — fakes omit it or place it incorrectly
- Seamaster: The wave-pattern dial must be ENGRAVED (tactile relief) — printed/flat wave lines = fake
- DON (Dot Over Ninety): small dot ABOVE the '90' on the Speedmaster tachymeter bezel — position/size often wrong on fakes
Serial number format: Omega serial number: 8-digit number on the caseback or between the lugs (on older models). Since ~2018 engraved on the caseback at 6 o'clock. Format: purely numeric. Verifiable on the Omega website with an extract from the archive.
