Grade 5 titanium, a grey silicon nitride ceramic bezel, and the METAS-certified Calibre 9900 inside — the Planet Ocean Chronograph in this configuration is Omega at its most technical and purposeful. The grey and orange color story gives it a distinct character that sits comfortably between serious tool watch and refined sport piece, and 600 meters of water resistance means this one means business.
