Until recently, the record for the deepest dive ever was in the Marianas Trench, at 10,916m deep, set by Jacques Piccard and Don Walsh in 1960, wearing a Rolex Deep Sea Special. That nearly 60-year-old record was broken by explorer Victor Vescovo, who went down a bit further, to 10,928m. And on his wrist was the Omega Seamaster Planet Ocean Ultra Deep Professional.
Rated to 15,000 meters, the titanium Ultra Deep Professional boasts the highest depth rating in the world (although sharing that title on paper with the Rolex Deepsea Challenge). At 28mm thick, it’s a hunk of a watch, but it may actually be considered slender when you consider its ability to withstand such pressure.
