Omega refuses to coast on the Planet Ocean’s decade-plus winning streak. The fourth-generation 600M is a ground-up rethink that somehow looks both brand-new and instantly familiar. They shaved the case down to a wearable 42mm × 13.8mm while sharpening every edge and lug like it’s 1957 all over again. The result is the thinnest, crispest Planet Ocean ever built.
Up front, a glossy ceramic bezel ring (pick orange, blue, or stealth black) sits flush against a matte black sandwich dial. Rhodium-plated hands and indexes are filled with clean white Super-LumiNova that glows ice-blue in the dark, and bold Arabic numerals mark the quarters for no-nonsense legibility at depth. Flip it over and the sapphire caseback shows off the METAS-certified Co-Axial Master Chronometer 8912—anti-magnetic to 15,000 gauss, 60-hour power reserve, and running with the kind of silky sweep only a coaxial escapement delivers.
True to its name, it’s pressure-rated to 600 meters and comes on either a color-matched rubber strap with a perfectly milled clasp or a redesigned steel bracelet that tapers aggressively for all-day comfort.
The old Planet Ocean was great. This one just made it obsolete.
