Omega Seamaster Aqua Terra 150M 30mm Ladies Watch White Ref. O22055302055001

The Omega Seamaster Aqua Terra 150M 30mm (Ref. O22055302055001 / 220.55.30.20.55.001) represents the pinnacle of Omega’s contemporary ladies haute horlogerie—uniting solid 18K Moonshine™ Gold jewelry craftsmanship, factory-set diamond brilliance, and true Master Chronometer mechanical engineering in an effortlessly wearable 30mm silhouette. Designed for collectors who refuse to choose between precious-metal elegance and serious Swiss movement capability, this reference balances luminous mother-of-pearl dial artistry with everyday 150-meter maritime durability.

Omega Seamaster Aqua Terra 150M 30mm in 18K Moonshine™ Gold & Diamonds

First formulated by Omega in 2019, proprietary 18K Moonshine™ Gold exhibits a subtler, paler champagne hue than traditional 18k yellow gold while incorporating palladium and silver to resist color fading over decades of wear. Framing the case of the Omega Seamaster Aqua Terra 150M 30mm is a radiant bezel set with 46 brilliant-cut diamonds. Beneath the domed scratch-resistant sapphire crystal with dual-sided anti-reflective treatment sits a natural white mother-of-pearl dial accented by faceted 18K Moonshine™ Gold hour markers, luminous hands, and a symmetrical circular date aperture positioned cleanly at 6 o’clock. The matching solid 18K Moonshine™ Gold bracelet features rounded polished-and-brushed links secured by a comfort-release butterfly foldover clasp.

METAS Co-Axial Master Chronometer Calibre 8751

Unlike quartz jewelry watches in this size category, the Omega Seamaster Aqua Terra 150M 30mm is powered by Omega’s self-winding Co-Axial Master Chronometer Calibre 8751, visible through a wave-edged sapphire exhibition caseback. Equipped with a free-sprung silicon Si14 balance spring, solid 18K Sedna™ Gold rotor and balance bridge, and George Daniels’ low-friction Co-Axial escapement, Calibre 8751 is independently certified by the Swiss Federal Institute of Metrology (METAS) to resist magnetic fields up to 15,000 gauss while maintaining 0/+5 seconds-per-day precision.
