Renowned for producing specialist diving watches, Oris is proud to introduce the Oris Aquis Depth Gauge. At the forefront of mechanical watch innovation, Oris has harnessed its knowledge, expertise and craftsmanship to produce the first divers watch which measures depth by allowing water to enter the timepiece. This patented timepiece is the first of its kind to measure depth using a unique gauge built into the sapphire crystal, which allows water to enter the watch. 

Back into the deep

Known affectionately as ‘the watch with a hole’, the Aquis Depth Gauge uses the scientific principles of the Boyle-Mariotte Law to create a gauge that clearly measures depth during a dive. The patented system works by allowing water through a hole cut into the sapphire crystal at 12 o’clock and into a channel milled around the outer edge of the crystal. This creates a watermark that corresponds to a gauge clearly indicated in yellow on the dial.

The new model captures and refines the spirit and functionality of the original, delivering even higher performance when it really matters deep below the ocean surface.

Three key improvements

The new Aquis Depth Gauge has three key improvements:

1. Depth gauge system
In the new watch, the process used to mill the channel into the out er edge of the crystal has been refined so the accuracy and legibility of the gauge are increased.

2. Metres to feet conversion chart
The case back has been re engineered so the metres to feet conversion chart is always set at 90 degrees to the 12 o’clock position. For divers relying on the chart on a regular basis, this will greatly enhance their experience of the watch.

3. Oris’s new patented Quick Strap Change system
Owners can now switch the stainless steel metal bracelet and rubber strap quickly, safely and securely without needing a tool or a visit to a jeweller.
