The Aquis Date Calibre 400 is the first wristwatch to feature Oris' revolutionary automatic movement, the Calibre 400.

The new Aquis Date, equipped with the Caliber 400, has several differences from previous models. First, the glossy blue dial features the "5 DAYS" inscription. The date window is large, with white inscriptions on a black background. The sapphire glass on the case back is the largest of any Aquis Date, allowing for maximum visibility of the movement.
