The central metric behind the momentum score. It filters out short-term swings and shows the true, medium-term market trend of this reference.
ℹ️ Volatility

The Aqua Terra O22050412102001 is one of the rare sports watches built entirely in 18-karat Sedna Gold — no gold-filled case, no bicolour compromise. Sedna is Omega's proprietary gold alloy, in production since 2012, and demonstrably holds its warm rose-gold colour longer than standard 18k rose gold. The 41 mm case is machined exclusively in this alloy: case middle, crown, lugs — solid throughout.
## The Dial: Silver with Teak Structure and Date
The silver-toned teak dial, defined by its horizontal line pattern, is one of the most recognisable design signatures of the AT family. In this reference, the Sedna contrast lends the dial a warmth that simply doesn't translate to a steel case. The date sits at 3 o'clock — properly integrated, not an afterthought. The polished bezel, fixed rather than rotating, underscores the watch's formal intent.
## Calibre 8901 — What the METAS Certificate Actually Means
Inside runs Calibre 8901, certified Master Chronometer. That means a rate accuracy of 0 to +5 seconds per day — verified across 8 positions over 10 days, under a magnetic field of 15,000 Gauss. No other Swiss sports watch manufacturer holds its movements to comparable certification requirements. On the pre-owned market, prices for this reference currently sit between $16,002 and $21,146 depending on condition and completeness. A full-gold AT with box and papers rarely surfaces quickly in this segment — collector turnover is low.
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.

What drives the price here
At $36,296 the watch sells well if the condition is right. A market rule of thumb: a complete set with box, papers and warranty card brings 10 to 15 percent more than the bare watch. Buying without papers can pay off, but you take the same discount again later when you resell.
What to look out for when buying?
- Authenticity: The serial number and reference on the case must match the papers. A professional authenticity check of the Omega Seamaster Aqua Terra 150M Co-Axial Master Chronome reliably rules out counterfeits.
- Condition: Check scratches on the case and bezel — professional refurbishment can leave traces.
- Service history: A documented service by the manufacturer or a certified watchmaker increases the value.
- Scope of delivery: Box, papers and warranty card make a noticeable price difference on the Seamaster Aqua Terra 150M Co-Axial Master Chronome.
- Independent certification: The CPS-52 standard covers 52 checkpoints — from the serial number and the timing machine to water resistance. The result is secured on the blockchain and can be verified at any time.
