The OMEGA Seamaster Aqua Terra Sedna Gold 38mm (Ref. 220.20.38.20.10.001) combines stainless steel and 18K Sedna gold construction with a sun-brushed light green dial, OMEGA’s proprietary rose gold alloy engineered to maintain its warm tone over time without colour degradation. The sailboat hull-shaped indexes with iridescent mother-of-pearl inlay and 18K Sedna gold ring on the small seconds subdial at 6 o’clock demonstrate consistent precious metal detailing throughout whilst the wave-edged caseback celebrates the collection’s maritime heritage.

At 38mm with 12.68mm thickness through steel and Sedna gold construction, this provides elegant proportions suitable for both formal and everyday wear whilst the 45mm lug-to-lug ensures comfortable fit across a broad range of wrist sizes. The sun-brushed green dial with 18K Sedna gold hands filled with white Super-LumiNova creates sophisticated colour harmony across the two-tone construction.

The Co-Axial Master Chronometer Calibre 8802 delivers 55-hour power reserve with 15,000 gauss magnetic resistance through METAS certification at the industry’s highest standard from the Swiss Federal Institute of Metrology. The free-sprung balance with silicon balance spring, small seconds display, and rhodium-plated rotor and balance bridge with Geneva waves in arabesque complete a movement specification visible through the transparent caseback.

The polished and brushed steel and Sedna gold bracelet with butterfly clasp provides secure and comfortable daily wear whilst the domed sapphire crystal with anti-reflective treatment on both sides ensures optimal clarity. The 150m water resistance covers practical requirements whilst the anti-magnetic certification adds everyday reliability.
