Omega Seamaster Aqua Terra 150M Co Axial Master Chronometer Small Seconds 38mm Ladies Watch
Ref. O22058382055002
Sits in Omega’s upper tier here — more premium than three quarters of the Omega watches we list, which start at £2,450.
Price range £2,450 to £33,000 across 10 Omega watches in stock.The Aqua Terra has always occupied the space between serious water resistance and wearable elegance, and this version in Sedna gold — Omega's proprietary rose gold alloy, warmer and more stable than standard 18k — represents its most dressed expression. The diamond-set bezel and the matching brackets around each index read as deliberate rather than decorative excess, because the proportions hold: at 38mm in solid gold, this is a watch that wears as jewellery without pretending it is not also a watch rated to 150 metres. What sets it apart from the case is what is happening inside the dial. The small seconds subdial carries its own ring of diamonds, which at this scale creates a second focal point that rewards closer attention. The red alligator strap on a Sedna gold deployant clasp is a considered choice — the warmth of the gold and the depth of the red work together in a way a neutral strap would not. The 8803 beneath the caseback holds METAS certification, which means it has been tested against magnetic fields up to 15,000 gauss and verified to chronometer standards stricter than COSC. In a watch designed first for the wrist, that is a significant assurance to carry quietly.

Learn more about Omega
Louis Brandt began assembling pocket watches in La Chaux-de-Fonds in 1848. His sons moved production to Biel in 1880 and, in 1894, released a calibre whose parts were fully interchangeable and which could be serviced by any watchmaker with standard tools. They named it Omega. The movement was successful enough that the company took its name.
Omega's history is bound up with measurement in public. It became official timekeeper of the Olympic Games in 1932 and has held the role for most Games since, which drove genuine engineering: photo-finish cameras, touchpads in swimming pools, and the timing systems that made hundredths of a second meaningful.
NASA qualified the Speedmaster for manned spaceflight in 1965 after testing chronographs from several manufacturers to destruction, and it was on Buzz Aldrin's wrist on the lunar surface in 1969. The watch has never been substantially redesigned.
The Seamaster line dates to 1948 and covers everything from dress watches to saturation diving instruments. Omega's technical position strengthened considerably after 1999 with the adoption of George Daniels' co-axial escapement, the first genuinely new escapement to reach series production in two centuries, and more recently through Master Chronometer certification testing resistance to magnetic fields at 15,000 gauss.
The company has been part of the Swatch Group since its formation.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 150m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 55 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
19mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as women's, though at 38mm it sits in the range that suits anyone.
Cheapest place to buy
Both Mappin & Webb and Goldsmiths list it at £24,500, so choose on delivery and warranty rather than price.
