Pre-owned Omega Seamaster Planet Ocean 600M ref 215.30.46.51.03.001 (2022) is a bold expression of Omega’s deep-sea engineering and modern design. The 45.5mm stainless steel case houses a rich blue ceramic dial with luminescent hour markers, a date at 6 o’clock, and twin chronograph counters designed for effortless legibility. The matching ceramic bezel features a Liquidmetal™ diving scale, durable, fade-resistant, and developed to handle true ocean depths. Powering it all is the Master Chronometer calibre 9900, visible through the sapphire caseback and tested by METAS for precision, magnetic resistance, and reliability under extreme conditions. With 600 meters of water resistance, a helium escape valve, and a robust stainless steel bracelet with an extendable clasp, this Planet Ocean is more than a dive watch. It’s a professional-grade instrument dressed in impeccable style. Shop OMEGA Seamaster Collection
