Oris Aquis Depth Gauge - Black Dial

Royal Jewelers is an authorized Oris dealer in the Boston area and offers the Oris Aquis Depth Gauge with Oris's 3 year warranty.

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.

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.

Oris is one of a small handful of Swiss watch brands that makes only mechanical watches. A mechanical watch is a thing of beauty, designed according to principles that have been around for generations and will continue long into the future. Oris is constantly striving to make better watches that offer beautiful, innovative functions and advanced performance levels. For example, the in-house developed Calibre 400 Series of Swiss Made automatics promises a five-day power reserve, anti-magnetism and a 10-year warranty and 10-year recommended service intervals.
