About this watch

The Omega Seamaster Planet Ocean 600M 42 mm 217.30.42.21.01.001 debuted in 2025. The watch features a 42 mm case in stainless steel with a combination of polished and brushed surfaces. It is fitted with a flat sapphire crystal with anti-reflective treatment on both sides, and water resistance is rated at 600 meters (60 bar). The screw-in case back is manufactured from grade 5 titanium and features the Omega seahorse emblem. The polished black ceramic bezel ring carries a diving scale in white enamel, while the inner ring is made of polished grade 5 titanium. The black dial has a matte finish and displays rhodium-plated hands and indexes filled with white Super-LumiNova. Four applied Arabic numerals complete the hour layout. A date window is not present on this model. Inside ticks the Omega Co-Axial Master Chronometer caliber 8912, certified by METAS. The movement operates at 3.5 Hz and has a power reserve of approximately 60 hours, using twin barrels mounted in series and a free-sprung balance with a silicon balance spring. The watch is fitted with a stainless steel bracelet featuring an extendable foldover rack-and-pusher clasp with an additional diver extension.
