Reference 215.30.40.20.04.001 represents the Planet Ocean 600m at a midsize 39.5mm, offering the full depth-rated capability of the collection in a more approachable case footprint. The round stainless steel case measures 14.16mm thick, is fitted with a scratch-resistant sapphire crystal, a transparent case back, and a screw-in crown — together delivering water resistance rated to 600 metres / 2,000 feet.
A clean white dial sits beneath that sapphire crystal, while a uni-directional rotating bezel frames the case. The brushed stainless steel bracelet is secured by a push-button folding clasp with push-button quick micro adjustment, allowing a precise fit without tools.
Inside beats an automatic Co-Axial Master Chronometer movement that carries COSC certification, meeting the rigorous timekeeping standards associated with Omega's Master Chronometer designation. This example is presented in new/unworn condition.
