About this watch
The Omega Seamaster Planet Ocean 600M 42 mm 217.30.42.21.01.002 debuted in 2025. It features a 42 mm stainless steel case with polished and brushed surfaces, fitted with a flat sapphire crystal featuring anti-reflective treatment on both sides. Water resistance is rated at 600 meters (60 bar). The screw-in case back is executed in grade 5 titanium and is engraved with the Omega seahorse emblem.
This version pairs the matte black dial with a polished blue ceramic bezel ring carrying a diving scale in white enamel; the inner ring is made from polished grade 5 titanium. The dial is fitted with rhodium-plated hands and indexes filled with white Super-LumiNova, along with four white Arabic numerals.
Inside ticks the Omega Co-Axial Master Chronometer caliber 8912. The movement operates at 3.5 Hz, uses twin barrels mounted in series, and provides a power reserve of approximately 60 hours. A free-sprung balance with a silicon balance spring ensures resistance to magnetic fields up to 15,000 gauss.
The watch is delivered on a polished-brushed stainless steel bracelet equipped with an extendable foldover rack-and-pusher clasp and an additional diver extension.
