Introduced in 2025, the Omega Seamaster Planet Ocean 600M boasts a robust 42 mm case crafted from stainless steel, showcasing a combination of polished and brushed finishes. It features a flat sapphire crystal treated with anti-reflective coating on both sides. Designed for extreme conditions, the watch is water-resistant up to 600 meters (60 bar). The caseback, which screws in securely, is made from grade 5 titanium adorned with the iconic Omega seahorse emblem.

This model highlights a striking orange ceramic bezel with a diving scale rendered in white hybrid ceramic, while the inner bezel consists of polished grade 5 titanium. The black dial has a matte finish and presents rhodium-plated hands and hour markers highlighted with white Super-LumiNova, complemented by four orange Arabic numerals. Powering this timepiece is the Omega Co-Axial Master Chronometer caliber 8912, which operates at a frequency of 3.5 Hz, incorporates twin barrels arranged in series, and provides around 60 hours of power reserve. The movement is equipped with a free-sprung balance and a silicon balance spring, conforming to METAS Master Chronometer prestige. Completing the package is a polished-brushed stainless steel bracelet featuring an extendable foldover clasp and an extra diver extension.
