Mastering pressure

Developed for professional saturation diving and extended deep-sea missions, the Sea‑Dweller combines a number of technical features to guarantee enhanced waterproofness, robustness and comfort in all conditions. This includes a slightly thicker crystal than that found on most other Rolex watches. Made in sapphire and scratch-resistant, the crystal is able to resist the massive pressure exerted by water at a depth of 1,220m/4,000ft and perfectly integrates into the overall design of the watch. The Cyclops lens affixed to the crystal, with a double anti-reflective coating, makes the date easier to read.
