Looking for new depths The Aquis Small Second Date 45.5 mm has a small seconds at 9 o'clock, the hand is coated with Super LumiNova® and shows that the watch is running even in poor lighting conditions - a very important feature for diving watches. It is also waterproof up to 50 bar (500 m), while the models in the Aquis Date series are usually only suitable for up to 30 bar (300 m). Otherwise, it has the same reliable features that divers have come to expect from the Aquis Date: a screw-down crown with protection, a unidirectional rotating bezel with a ceramic insert, and either a metal or rubber strap with Oris' patented safety folding clasp with extension.
