Oris Aquis Date Calibre 400: An evolution in diving watch design

The Oris Aquis Date is presented for the first time with the impressive Calibre 400 and a more compact 41.5mm case. Available in blue, anthracite or green dial, this diver's watch offers a new level of versatility.

Unique features of the Calibre 400

The Aquis Date, equipped with the Calibre 400, is very different from the standard models. The blue gradient dial proudly bears the inscription '5 days', a reference to the movement's impressive power reserve. The date window is larger, the date ring is black instead of white, and the sapphire crystal case back provides an unparalleled view of the movement.

Robustness in the Underwater Realm

Despite these innovations, the watch remains water-resistant to 30 bar (300 meters) and retains its unidirectional rotating bezel with scratch-resistant ceramic insert for safe dive timing. The SuperLumiNova® -coated hands and indices ensure clear readability, even in deep waters.

Innovation with Quick Strap Change System

The Oris Aquis Date Calibre 400 proudly features Oris' Quick Strap Change System - a patented development that makes changing straps a breeze. Simply by lifting a tab, you can effortlessly swap your strap without the need for tools or expert assistance.

New Standards for Diving Watches

This watch combines innovation, aesthetics and functionality in a unique way, setting new standards in the field of diving watches. The Oris Aquis Date Calibre 400 is not just a timepiece, but an expression of precision and style underwater and beyond.
