220.55.30.20.55.001 Seamaster
A superb tribute to OMEGA’s rich maritime heritage, the Seamaster Aqua Terra is a refined 30mm model. Its exquisite proportions are achieved through OMEGA's advanced Co-Axial Master Chronometer calibre 8751, certified at the industry's highest standard by the Swiss Federal Institute of Metrology (METAS).
This stunning timepiece is entirely fashioned from 18K Moonshine™ Gold, featuring a symmetrical polished case and a screw-in caseback with a wave-edged design. A highlight is the polished bezel, set with 46 diamonds, which encircles the mesmerizing full glossy pearled white mother-of-pearl dial. This dial boasts a circular date window at 6 o’clock, 11 diamond hour markers, and elegantly redesigned faceted hands with a delicate minute hand taper. All applied elements are in 18K Moonshine™ Gold, with the hands crafted in 18K yellow gold with a PVD Moonshine™ Gold coating, and both filled with white Super-LumiNova for luminescence. The watch is presented on a seamlessly integrated 18K Moonshine™ Gold bracelet, complete with beautifully rounded polished-brushed links, a secure foldover butterfly clasp, and OMEGA’s easy comfort-adjustment system for unparalleled comfort.
