The Omega Aqua Terra 30 with reference O22010302003001 carries the internal nickname My Little Secret AT30 — and the name says it all. Beneath the visible blue of the AT30-Blau-03 dial hides a second dial, revealed only by pressing the crown. Omega introduced this concept into the Aqua Terra line in 2014, and it has remained a niche offering with a loyal following of collectors ever since.
## Caliber 8750 Beneath the Polished Steel Bezel
The watch is powered by the Caliber 8750, a Co-Axial Master Chronometer movement with a 55-hour power reserve and a balance frequency of 3.5 hertz. The fixed bezel, in the Fixed-Steel-Polished-AT38 finish, forgoes any engraving or diamond setting — a deliberate contrast to the playful mechanism hidden beneath the dial. It's precisely this outward restraint that makes the reference appealing to collectors who value the understated character of the Aqua Terra family.
## Why the Reference Remains a Footnote in the Market
No production changes have been documented for O22010302003001 — the reference appears to have run unchanged throughout its entire production. That makes valuation more straightforward than for references with multiple dial variants, though supply on the secondary market remains thin. Anyone looking for a My Little Secret AT30 is usually searching for this exact model — chance finds are rare. With only one known dial execution and a single bezel variant, this reference ranks among the more clear-cut cases in Aqua Terra history.
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.
