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.
