From the renowned makers of specialist diving watches comes the first divers watch which measures depth by allowing water to enter the timepiece. Water resistant up to 50 bar, the Oris Aquis Depth Gauge measures depth using a unique gauge built into the scratch resistant domed anti-reflective sapphire crystal, which allows water to enter the watch. It features a stainless steel metal case and bracelet with an additional rubber strap and professional strap changing tools.
