The 220.10.38.20.10.003 has been the steel bracelet model of the new 38 mm Aqua Terra Green family since February 2024. Omega launched the generation in three variants simultaneously: the Small Seconds model on Calibre 8802, a rubber version called Shades Bay Green, and this .10.003 on steel bracelet. The 38-millimetre format is Omega's answer to wrists under 17 centimetres that never sat quite right with the dominant 41 mm proposition. Calibre 8800, date at 3 o'clock, fixed polished steel bezel — retail price 6,900 euros in the EU and 6,300 US dollars.
## The Dial That Makes the Difference
Collectors call it Green Teak, because the teak relief pattern has been the Aqua Terra's defining signature for years — and this is the first time it has appeared in this green tone on 38 millimetres. The horizontal lines run across the entire dial surface, lending it a shifting sense of depth depending on the light. Calibre 8800 is Master Chronometer certified, which means — among other things — 15,000 Gauss magnetic resistance and a rate accuracy of 0/+5 seconds per day to METAS standard.
## What the .10.003 Shows in the Pre-Owned Market
The reference is still young, and the data picture is correspondingly thin. In the first months after launch, grey market prices ran noticeably below retail — a sign of wide availability and no demand overhang. Within the AT 38 Green family, the Teak version on steel is the most straightforward choice: no rubber strap, no small seconds upgrade. For collectors positioning for price movement, the rubber version remains the more interesting bet.
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.
