Watch Fact of the Day: The Mystery of Rolex's First Deep-Sea Record So, back in 1960, Jacques Piccard and Don Walsh took a wild dive in the Trieste bathyscaphe to the Mariana Trench, bringing along an experimental Rolex Deep Sea Special strapped to the outside. This watch handled insane pressures over 10,000 meters deep, proving Rolex's mechanical genius. When they surfaced after 8.5 hours, the watch was still ticking accurately—like a champ! Fast forward to 2012, filmmaker James Cameron took his own dive, bringing along the vintage watch as a lucky charm. Rolex later launched a production version, tying it all back to those epic deep-sea adventures. Talk about a legacy!
