Oris Aquis Date Caliber 400

For the first time, the Oris Caliber 400 appears in an Aquis Date with a smaller 41.5 mm case. The diving watch is available with a blue, anthracite or green dial.


The Aquis is known around the world as an icon of modern diving watch design. Resistant, reliable and equipped with a wide range of functions, it is chosen by women and men of all stripes who love watches.


The new Aquis Date, equipped with the Caliber 400, differs from the standard model in a number of ways. A first indication of what's inside is the words '5 days' on the gradient blue dial. The date window is larger and the date ring is black instead of white. The sapphire crystal back is the largest Oris has ever mounted on an Aquis Date, so nothing obstructs the view of the movement.


Nevertheless, the watch is still water-resistant to 30 bar (300 meters), has a unidirectional rotating bezel with a scratch-resistant ceramic inlay for safe diving timing, and hands and indices with SuperLumiNova®. It also features Oris' latest patented development, the Quick Strap Change System, which allows straps to be changed simply by lifting a tab. Completely without tools or specialists. In short, the Oris Aquis Date Caliber 400 sets new standards for diving watches!
