Rolex watches are inseparable from the Trieste and the Deepsea Challenge. In these two historic dives, the experimental Rolex watch attached to the hull, 11 kilometers below sea level, was subjected to the most significant water pressure on earth. Still, both times worked perfectly, showing that Rolex watches are unparalleled. Waterproof performance. Rolex pioneered the conquest of the deep sea with innovative inventions. The Oyster watch, launched in 1926, was the world’s first waterproof timepiece, and then successively launched the Oyster Perpetual Submariner (1953), Sea-Dweller (1967), and Rolex Deepsea (2008) professional diving watch.

It is also a benchmark for quality movements in the future.
