Other features that make the Oris Aquis Depth Gauge suitable for professional diving are its stainless steel case, which is water-resistant to 500 meters and has an engraved meters-to-feet conversion scale on the screw-down caseback so international diving enthusiasts can make quick calculations; its unidirectional rotating bezel, with minute scales on a black ceramic inlay; and the easily adjustable folding clasp, which also has an “anchor” safety feature that prevents the watch from falling off the wrist.
The movement is the automatic Oris Caliber 733, based on an SW 200, which powers the central hours, minutes and seconds and the date display at 6 o’clock. The dial’s indices and hands are coated with white Super-LumiNova, which, Oris says, offers excellent underwater legibility. The case’s screw-down security crown is embedded into and protected by a stainless steel safety barrier.
The watch, which comes on a rubber strap, is packaged in a special waterproof case with several useful accessories: a replacement metal bracelet, a set of tools to change the straps; a certificate with details on the Aquis Depth Gauge’s technology, and a specially configured cleaning device for the sapphire crystal. The whole ensemble will cost you just $3,500.
