About this watch

The Omega Seamaster Planet Ocean 600M 42 mm 217.32.42.21.01.001 debuted in 2025. It features a 42 mm stainless steel case with polished and brushed surfaces, fitted with a flat sapphire crystal with 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 bears 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 is fitted with rhodium-plated hands and indexes filled with white Super-LumiNova, along with four applied rhodium-plated Arabic numerals. Inside ticks the Omega Co-Axial Master Chronometer caliber 8912. The movement operates at 3.5 Hz and provides a power reserve of approximately 60 hours, using twin barrels mounted in series and a free-sprung balance with a silicon balance spring. This version is delivered on a black rubber strap with a stainless steel case-link and a foldover clasp.
