In 2013 Oris launched the Aquis bathymeter, which has been hailed by the international media as the most innovative diving watch. It solves the challenge of how to build a depth gauge into a mechanical watch. Oris also received a patent for this groundbreaking design.
The Oris Aquis depth gauge is the first diving watch to measure the depth of the water without using any moving parts, and Oris makes this feature seem surprisingly simple, and the dive depth is clear at a glance.
This new Aquis bathymeter (model: 01 733 7675 4754-Set RS), launched in 2015, features a bright yellow rubber strap, a 46 mm stainless steel black DLC-coated case, and a unidirectional rotating tungsten metal watch Ring, the material is as hard as a gem. Oris 733 fully automatic movement, calendar window at 6 o’clock, 38-hour power reserve.
Black dial with date display at 6 o’clock. An entry hole is set at 12 o’clock on the mirror surface, and a channel is embedded along the outer edge of the mirror surface. The thickness of this watch is 4.5 mm. The small hole allows water to enter the channel, and a yellow depth mark is printed on the faceplate to show the water level, giving the diver a clear reading of up to 100 meters, while the watch is still waterproof to 500 meters.
The inspiration for this innovation comes from Boyle’s law, applying the “pressure * gas volume = constant” stated in the law. As the diver dives into the deep sea while wearing a watch, the pressure increases, compressing the volume of air in the channel. Oris Aquis bathymeters use this principle to allow water to enter the watch through a small hole.
The hour markers and hands are coated with a luminous coating for fast reading of time in any environment.
Large stainless steel black DLC-coated crown for easy operation.
A bright yellow rubber strap was unveiled and has two original designs. The first is a safety anchor design to prevent the strap from breaking out, and it can be worn securely even under severe impact. The second is a sliding buckle for wearing. The user can freely adjust the size of the strap without unfastening the buckle.
Tungsten diving bezel, hard as a gem, can be rotated in one direction.
The watch has a dense bottom design and is equipped with the Oris 733 automatic winding movement, which provides a 38-hour power reserve.
In summary: the water depth measurement of this watch seems surprisingly simple. It perfectly follows the brand idea, explores various ways, and creates the best watch at the most reasonable price. At present, this watch is on the market. It uses a special waterproof case and comes with a black rubber strap and strap replacement tool.
