Launched in 2005, the Omega Seamaster Planet Ocean continues to embody the brand’s maritime spirit through innovation, precision, and enduring design. This 43.5 mm model pairs rugged functionality with refined aesthetics, featuring a brushed stainless-steel case and a black ceramic bezel ring engraved with a Liquidmetal™ diving scale — a hallmark of Omega’s material mastery.

The sand-blasted “gunmetal” grey dial, enhanced by a galvanic finish, evokes the texture of deep ocean steel. Beige and white transferred accents highlight the date window at 3 o’clock, while the PVD stainless-steel Arabic numerals, hands, and hour markers — filled with beige Super-LumiNova — provide luminous clarity even in the depths. Beneath the surface, the watch is powered by the Omega Co-Axial Master Chronometer Calibre 8900, METAS-certified for accuracy, magnetic resistance up to 15,000 gauss, and a 60-hour power reserve.

The caseback, equipped with Omega’s patented NAIAD LOCK system, ensures that the engraved text remains perfectly aligned and features a metallized seahorse emblem visible through the sapphire crystal window. Completing the look is a dark grey structured rubber strap with contrasting beige stitching and a stainless-steel foldover clasp, achieving a seamless blend of durability and sophistication.
