With its new Aquis Dept Gauge Diving watch, Oris introduced a truly innovative way of depth measuring. Briefly, during diver’s descending, this interesting mechanical timepiece allows water to enter a special channel and to compress air, which further provides a visual reference point on a depth scale. Beside this cool innovation, the new Oris Diver watch deserves compliments for great sporty design, robust construction and superb water-resistance up to 500 meters (about 1650 feet).
In order to measure depth, great majority of divers uses a high-tech digital computer. However, those who have greater confidence in mechanical timepieces, now have a chance to get all necessary information from new Oris Aquis Dept Gauge Diving watch. As the Swiss brand marks, this new technology is particularly useful in decompression breaks in lesser depths, since it benefits neither from inertia, nor from delaying the accurate and actual depth indication. The secret is in the practical use of the Boyle Mariotte Law, according to which the absolute pressure and volume of a given mass of confined gas are inversely proportional.
Thus, by following this principle, Oris developed a very sophisticated and unique depth gauge system. The Aquis features an extra-thick sapphire crystal, with a channel milled into the side. (You can see it goes counterclockwise, around the outer rim of a diam, from 12 to 1 o’clock position.) At the 12 o’clock position, there is an aperture that allows water to enter this channel and compress the air within. On descending, the water-pressure is higher, while it decreases with ascending. The difference between water and compressed air is visible, which allows reading a depth on the scale that runs around the perimeter of the dial (from 1 to 100 meters below surface).
Oris Aquis Depth Gauge is a robust watch, with the case diameter of 46mm, which ensures easy-handling and great readability of its wide dial. It is crafted in stainless steel and fitted with a high-quality rubber strap. Besides, the watch comes with an alternative steel bracelet. As another highly useful diving feature, the watch incorporates a unidirectional turning bezel with a black ceramic inlay and a minute scale, for measuring of diving time.
Beside the Depth Gauge indicator, a black dial features highly luminous hour indices and hands, as well as the date window at the 6 o’clock position. The watch is powered by an ETA-based, Oris-modified, Calibre 733 self-winding mechanism. The price of this innovative diving model is CHF3,500.
