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 cutin to 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 functional ity 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.
