The Oris AquisPro 4000m REF 01 400 7777 7155 sets a new standard in professional diving watches with its remarkable 400-bar (4,000 meters) water resistance. Its robust multi-piece titanium case is paired with a blue gradient dial featuring a wave pattern, protected by a dual-domed sapphire crystal with anti-reflective coating inside for superior legibility.

Equipped with the patented Rotation Safety System bezel, developed in collaboration with professional divers, the bezel locks securely in place to prevent accidental adjustment. The titanium screw-down security crown and the titanium case back with special engravings further emphasize its professional-grade build.

Powered by the high-performance Oris Calibre 400 automatic movement, this watch offers a 120-hour power reserve, elevated anti-magnetism, chronometer-level accuracy, and is backed by a 10-year warranty with recommended 10-year service intervals. The blue ceramic bezel insert features a minute scale ideal for dive timing, while the blue rubber strap includes a titanium security folding clasp with an extension system for effortless length adjustment while worn.
