Seamaster Planet Ocean Ultra Deep 6000m Co-Axial Master Chronometer 45.5mm 215.30.46.21.03.002

As part of the Five Deeps Expedition in 2019, the Ultra Deep concept watch made history when it reached the deepest place on Earth. Following that World Record dive, OMEGA produced a collection for everyday adventurers. A watch tested in real ocean conditions during its development, water-resistant to 6,000 metres (20,000 ft.), and meeting the ISO 6425:2018 standard for saturation divers’ watches, as certified by the Swiss Federal Institute of Metrology (METAS).

This 45.5 mm model has a case and bracelet in robust O-MEGASTEEL and an extraordinary dial that pays homage to the mysteries of the deep. Its pattern is an accurate representation of the bottom of the Challenger Deep, the deepest point in the Mariana Trench, mapped by the Five Deeps team using almost one million sonar points. Its lacquered finish, produced by letting an ocean of lacquer flow across the dial, has a beautiful sense of depth. The dial even has a playful side. Shining a UV light reveals the words, OMEGA WAS HERE, pointing toward the world record dive of 10,935 metres (35,876 ft.) and showing the Western, Central and Eastern Pools.

The caseback has a laser-engraved commemorative Seamaster logo depicting a trident-bearing Poseidon and two seahorses: OMEGA’s 1956 original and the brand’s current design. Behind which sits the OMEGA Co-Axial Master Chronometer calibre 8912.
