In 2019, as part of the Five Deeps Expedition, the Ultra Deep concept watch made history by reaching the deepest point on Earth. Following this world record dive, OMEGA introduced a collection designed for everyday adventurers. Tested in real ocean conditions during its development, the watch is water-resistant to 6,000 meters (20,000 feet) and meets the ISO 6425:2018 standard for saturation diver's watches, certified by the Swiss Federal Institute of Metrology (METAS).

      This unworn 45.5 mm model features a case and bracelet made from O-MEGASTEEL, known for its durability, and a striking dial that honors the mysteries of the deep. The dial's pattern mirrors the bottom of the Challenger Deep, the lowest point in the Mariana Trench, mapped by the Five Deeps team using nearly one million sonar data points. Its lacquered finish, created by letting a wave of lacquer flow across the surface, gives it a captivating sense of depth. A fun detail: when exposed to UV light, the words "OMEGA WAS HERE" appear, marking the historic dive to 10,935 meters (35,876 feet) and highlighting the Western, Central, and Eastern Pools of the Mariana Trench.

     The caseback features a laser-engraved commemorative Seamaster logo, depicting Poseidon with his trident and two seahorses: the original design from 1956 and the modern version. Inside, the watch is powered by the OMEGA Co-Axial Master Chronometer calibre 8912. The watch has been sized at the original time of purchase, but the links have been put back into the bracelet. The warranty card was activated in January of 2025. The watch will ship as a full set.
