Oris Aquis Depth Gauge Stainless Steel 45.80mm Rubber Strap
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. Stainless steel case, ceramic minutes scale top ring. 45.80 mm. Automatic. Date window. Black dial with indices and hands Superluminova BG W9. Black rubber strap. 38 hour power reserve. Reference# 01 733 7755 4154-SET.
