The AquisPro Date is a natural home for Oris’s high-performance Calibre 400. 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. Among its special features is Oris’s patented Rotation Safety System, known as RSS. This exclusive Oris device, commissioned by the professional diving community, enables the wearer to adjust and lock the uni-directional rotating bezel into place. This means that during a dive they can read off remaining dive time with absolute certainty. 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.
