The Oris Aquis line of modern durable diving watches is iconic in its class. The Aquis Depth Gauge uses a patented system based on the Boyle-Mariotte Law to allow a diver to clearly measure depth during a dive. The depth gauge works by allowing water through a hole cut in to the sapphire crystal near the 12:00 index, and into a channel carefully milled around the outer edge of the dial.
