Introduced in 2025, the Omega Seamaster Planet Ocean 600M boasts a robust 42 mm stainless steel case that showcases both polished and brushed finishes. The watch is topped with a flat sapphire crystal that is treated to minimize reflections on both sides, ensuring visibility under various conditions. It is built to withstand water pressure up to 600 meters (60 bar), making it ideal for deep-sea adventures. The case back, designed with a screw-in mechanism, is crafted from grade 5 titanium and features the iconic Omega seahorse emblem.

The timepiece is equipped with a striking black ceramic bezel, which is accentuated by a diving scale inlaid with white enamel. The inner bezel ring, also made of polished grade 5 titanium, adds to its sophistication. The black matte dial is adorned with rhodium-plated hands and indexes, all filled with white Super-LumiNova for optimal readability in low light, while four applied Arabic numerals mark the hours. Notably, this model does not include a date display.

At the heart of the watch lies the Omega Co-Axial Master Chronometer caliber 8912, which has earned METAS certification for its precision. Operating at a rate of 3.5 Hz, the movement features a power reserve of about 60 hours, utilizing twin barrels arranged in series and a silicon balance spring with a free-sprung design. The watch is completed with a stainless steel bracelet that includes an extendable foldover rack-and-pusher clasp, offering an additional diver extension for comfort.
