Oris Watch Aquis Date Calibre 400 Blue Bracelet 01 400 7769 4135-07 8 22 09PEB.  Based predominantly on dive watch functionality, the Oris Aquis Date Calibre 400 41.5mm watch certainly underscores Oris’ clear commitment towards sourcing the very best in materials when it comes to taking to the water. Yet this variation of the dive watch emphasizes the brand’s sophisticated route to timekeeping. The watch is equipped with the Calibre 400, an in house made movement that provides an impressive 5 day power reserve thanks to its twin barrels. Each barrel features an extended mainspring that enables it to guarantee a two and a half day power reserve and the movement is built from silicon parts to ensure the best anti magnetic protection. The Oris Aquis Date Calibre 400 41.5mm watch features a striking ocean blue dial adorned with hands and indexes that glow richly in dark conditions thanks to superior luminous technology. These Super LumiNova elements are paired with an anti glare and scratch resistant sapphire crystal glass front, which also grants a clear view into the dial’s credentials when needed. The Oris Aquis Date watch features a date aperture at 6 o’clock surrounded by a matching blue ceramic unidirectional rotating bezel for effortlessly tracking remaining dive time. To prevent water from leaking into the already 300 meter water resistant stainless steel multipiece case, the model also features a screw down crown and protection system. To complete its diver ready look, the Oris Aquis Date Calibre 400 41,5mm watch wraps around the wrist with a solid steel bracelet. The bracelet secures with a folding clasp and a diver extension mechanism, but also features Oris’ innovative Quick Strap Change technology, enabling the watch to be switched onto a black rubber strap if desired.
