Omega Seamaster Planet Ocean 43.5mm Automatic Specs

That’s because the Planet Ocean 43.5mm is about as souped-up as a dive watch can get while still being wearable. For Omega, the Planet Ocean has always been one of its most tech-forward watches. When the Planet Ocean was unveiled in 2005, it was the first Omega dive watch to use a co-axial escapement. Eleven years later, in 2016, when the Planet Ocean was most recently updated, Omega announced that the Planet Ocean series would be the first Seamasters to be certified as Master Chronometers.

The Planet Ocean 43.5mm uses a METAS-certified co-axial caliber 8900 that you can see through the sapphire caseback. The stainless steel case measures a substantial 43.5mm by 16mm, and the watch has 600 meters of water resistance, double that of the slightly more pedestrian Seamaster 300m. The Planet Ocean is the dive watch for those who need – or, perhaps just want – a modern dive watch that’s pushing the limits of what a dive watch can be. Sure, the new Ultra Deep now pushes those limits 10 times deeper (to a hardly fathomable 6000 meters of water resistance), but the Planet Ocean feels more accessible, like more of an everyday watch. Top it off with a ceramic bezel, and the Planet Ocean Co-Axial Master Chronometer 43.5mm has all the specs it needs to keep enduring as the core of the Planet Ocean lineup for years to come.
