About this watch

The Omega Seamaster Planet Ocean 600M 42 mm 217.32.42.21.01.002 debuted in 2025. The case measures 42 mm and is executed in stainless steel with polished and brushed surfaces. A flat sapphire crystal with anti-reflective treatment on both sides covers the dial. Water resistance is rated at 600 meters (60 bar). The screw-in case back is made from grade 5 titanium and features the Omega seahorse emblem. This version pairs the matte black dial with a polished blue ceramic bezel ring bearing a diving scale in white enamel; the inner ring is polished grade 5 titanium. The dial is fitted with rhodium-plated hands and indexes with white Super-LumiNova, along with four white Arabic numerals. Inside ticks the Omega Co-Axial Master Chronometer caliber 8912, operating at 3.5 Hz with twin barrels in series and a free-sprung balance with a silicon balance spring. The power reserve is approximately 60 hours, and the movement meets METAS Master Chronometer certification standards. The watch is delivered on a black rubber strap with a stainless steel case-link and a foldover clasp.
