Oris Aquis Depth Gauge Chronograph

World renowned Swiss watch brand Oris is introducing a new chronograph version of its iconic diver’s watch, the Aquis Depth Gauge, the first mechanical watch to measure depth without any moving part.

This functional diver’s watch follows in the footsteps of the acclaimed Aquis Depth Gauge, which was widely regarded as one of the most innovative diving watches ever made when it was launched in 2013. It solved the problem of how to incorporate a depth gauge into a mechanical watch.

Oris equipped the Aquis Depth Gauge with an inlet in the crystal at 12 o’clock, leading to a channel milled into the outside edge of the crystal covering the dial. As the diver descends, air inside the channel compresses, allowing water through the inlet and into the channel. This creates a watermark that corresponds to yellow depth gauge indications marked on the dial, giving the diver a clear reading of the depth. The watch is water-resistant to 50 bar (500 metres).

The Aquis Depth Gauge Chronograph houses Oris’s automatic calibre 774, which powers a chronograph function and a date window at 6 o’clock. The heavy-duty watch has a multi-piece 48mm stainless steel case. Its screw-in crown is protected from accidental knocks by a crown-protection system. The watch has a black dial with applied indices and nickel hands filled with white Super-LumiNova® to boost underwater legibility. Expertly crafted, the Oris Aquis Depth Gauge Chronograph has a tough 4.0mm thick sapphire crystal, which is twice as thick as an average top glass. The milled channel is indicated in blue.

The watch comes with a black rubber strap fitted with Oris’s clever quick adjustment sliding-sledge folding clasp system, enabling the wearer to adjust the strap or bracelet without taking the watch off, and the Oris-developed safety anchor, which prevents the watch from falling off even when it comes undone.

The Oris Aquis Depth Gauge Chronograph is presented in a special waterproof case with an additional metal bracelet and strap change tools. In Switzerland, retail price of Oris Aquis Depth Gauge Chronograph is approximately CHF 4,900/Set.
