The new AquisPro Date Calibre 400’s spec list continues with a high-grade, lightweight titanium case plated in low-glare black DLC that makes its 49.50 mm case diameter extremely comfortable on the wrist. A chunky rubber grip makes it easy to operate, even when gloved, while a yellow and white minutes scale engraved into the scratch-resistant ceramic bezel insert delivers high levels of low-light legibility. This means that during a dive they can read off remaining dive time with absolute certainty. This exclusive Oris device, commissioned by the professional diving community, enables the wearer to adjust and lock the uni-directional rotating bezel into place.

Designed to serve professional divers on saturation dives, it’s a highly technical tool watch chosen by divers who work on complex engineering projects in helium-enriched environments hundreds of metres below the water’s surface.Īmong its special features is Oris’s patented Rotation Safety System, known as RSS. The AquisPro Date is a natural home for Oris’s high-performance Calibre 400. Boasting elevated levels of anti-magnetism, superior accuracy compared to a chronometer, a five-day power reserve and a 10-year guarantee, Calibre 400 is the new standard in Swiss Made automatic mechanical movements. Oris’s professional diver’s watch, the AquisPro Date, is the latest watch to be equipped with Oris’s in-house Calibre 400 movement.
