Planet Ocean

The professional diver of the Seamaster family, since 2005

Line History

The Seamaster Planet Ocean is born in 2005 as Omega's response to the growing demand for dive watches with more extreme technical specifications than the Diver 300M, which had meanwhile become a diver more oriented toward everyday, elegant use as well. The debut comes with 42 and 45.5 mm cases, water resistance up to 600 meters and an instantly recognizable style: hands and indices with a strongly pronounced arrow shape, a domed sapphire crystal and a black-and-orange aluminum bezel that, together with the black-and-black variant, would become the collection's most identifiable color combination.

Technically the Planet Ocean debuts with the Co-Axial 2500 caliber, introduced a few years earlier in the Omega range, and with a manual helium escape valve at 10 o'clock, designed for professional divers using saturation gas mixes. In 2011 the line moves to a second generation with the manufacture caliber 8500/8501, also available in titanium, while later versions introduce ceramic cases and Master Chronometer certification issued by the METAS institute, which subjects movements to additional tests for resistance to magnetic fields.

A link to cinema reinforces the line's popularity: in the 2006 film "Casino Royale," Daniel Craig, in his debut as James Bond, wears a Seamaster with the caliber 2500 closely related to the Planet Ocean aesthetic, while later advertising campaigns for the saga have often paired the line with the more traditional Diver 300M, consolidating Omega's image as agent 007's official brand on the high-performance diving front as well.

The most extreme point in the collection's history arrives in 2019, when three examples of the Seamaster Planet Ocean Ultra Deep Professional, developed specifically for the occasion, accompany an oceanographic expedition down to the deepest point of the Mariana Trench, 10,928 meters below sea level, surviving the pressure and setting a record for the deepest-diving functioning wristwatch in the ocean: an achievement that carries the line's professional vocation, born in 2005, to its most extreme technical consequences.

Fun Fact

During the 2019 Mariana Trench expedition, the three Planet Ocean Ultra Deep Professional watches were not worn on a human wrist, but mounted on the outside of the submersible "Limiting Factor": the depth reached, nearly 11,000 meters, nonetheless remains the absolute record for a wristwatch that has ever functioned correctly underwater.
