Reference 215.15.40.20.01.001 presents the Planet Ocean 600m in a round stainless steel case measuring 39.5mm across and 14.16mm thick. A screw-in crown, 600m/2000ft water resistance rating, and uni-directional rotating bezel speak to its diving heritage, while scratch-resistant sapphire crystal and a transparent case back add refinement to its sport-ready construction.
The black dial sits beneath the sapphire crystal, offering clear legibility, while the automatic Co-Axial Master Chronometer movement powers the watch from within. A brushed stainless steel bracelet secured by a push-button folding clasp with push-button quick micro adjustment rounds out the package, keeping the overall aesthetic cohesive and purposeful.
This is a midsize interpretation of one of Omega's most capable Seamaster lines — a watch that carries genuine depth-rated performance in a case sized for a broad range of wrists.
