Oris Watch Aquis Date Calibre 400 Blue Rubber 01 400 7769 4135-07 4 22 74FC.  Reflecting the deep blue tones of the ocean, the Oris Aquis Date Calibre 400 41.5mm is as ready to take on the water as ever, this time with its smaller case size of 41.5mm and an impeccably crafted Calibre 400 powering away inside its rugged case. The movement is developed entirely in house at Oris and is the first to be equipped to the heart of a smaller sized Oris Aquis case. The movement delivers an impressive 5 day power reserve and consists of silicon components to guarantee an exceptional anti magnetic construction, as well as twin barrels to enable it to produce its impressive 5 day power reserve. The stunning blue dial of the Oris Aquis Date Calibre 400 41.5mm watch is adorned with the recognisable luminous coated hands and indexes, as well as a legible date aperture located at 6 o’clock. Surrounding the dial is a matching blue ceramic diver’s bezel with a 60 minute dive scale. It rotates unidirectionally to ensure dive time can never accidentally become extended. The Oris Aquis Date Calibre 400 41.5mm watch also features a domed anti reflective front and a scratch resistant sapphire crystal glass caseback. The latter remains an integral part of the design of this Oris Aquis watch, since the brand intended to highlight the beauty of the mechanical engine whilst in motion. To complete the diver ready look of the Oris Aquis Date Calibre 400 41.5mm watch, the 300 meter water resistant dive watch is completed on a comfortable Oris embossed black rubber strap. Oris’ Quick Strap change technology also enables the wearer to switch the strap over with a steel bracelet if desired.
