describeAs part of the 2019 Five Oceans Deeps Expedition, the OMEGA Ultra Deep dived to the deepest point in the Mariana Trench, setting a world record for deep diving watches and creating a milestone. Today, OMEGA continues to keep pace with the times and develop this revolutionary professional diving watch into a new watch that can be sold to the public. During the product development process, OMEGA tested this watch in a real ocean environment, with a water resistance of up to 6,000 meters (20,000 feet), and passed the International Organization for Standardization (ISO) 6425:2018 saturation diving watch certification, as well as the Swiss Federal Institute of Metrology (METAS) recognized Master Chronometer certification. ??The case diameter of this watch is 45.5 mm. The case and bracelet are made of O-MEGASTEEL stainless steel alloy developed by OMEGA, which is durable. The unique dial design pays tribute to the deep sea. The dial pattern faithfully reproduces the scene at the bottom of the "Challenger Deep" in the Mariana Trench. This pattern was drawn by the "Five Oceans Deep Expedition" team using nearly one million sonar points. The lacquer treatment on the dial is like seawater flowing through the dial, presenting a unique and spectacular view of the seabed. The dial design also hides mysteries. When ultraviolet rays shine on the dial, the words "OMEGA WAS HERE" appear in front of you, reminding you of the 10,935-meter deep diving world record created by the Ultra Deep prototype watch. In addition, the dial also shows the West Pool, Middle Pool and East Pool at the bottom of the Challenger Deep, which is unique and interesting. ??The case back is decorated with a unique commemorative seahorse logo laser-engraved, depicting the sea god Poseidon holding a trident and riding two seahorses, which are the seahorse logo originally designed by Omega in 1956 and the current seahorse logo. The watch is equipped with the Omega 8912 Master Chronometer movement.Case diameter: 45.5 mmLug to lug distance: 22mmDistance between upper and lower lugs: 51.9mmThickness:18.1 mm.Case: Oa??MEGASTEELWater resistance: 600 atmospheres (6000 meters/20000 feet)Total product weight (approx.): 254 gDial color: blueMirror: Arched, wear-resistant sapphire glass, double-sided anti-reflective treatment Material: Oa??MEGASTEELClasp type: retractable folding claspAdvantages of this watchThe watch is equipped with revolutionary innovative movement components to ensure that all performance of the watch meets the industry's higher standards.
