Aquis Date Calibre 400- New Oris Timepiece is Avant-Garde

July 12, 2021:  The new Oris Aquis Date Calibre 400 41.5 mm series is both modern and avant-garde with heavy wide crown guards, and short angular semi-integrated lugs making this watch one of unique proportions that is considerably more compact on the wrist than other diver watches. 

Oris Calibre 400 Series sets the new standard in automatic mechanical watchmaking. Conceived entirely in-house by the independent Swiss watch company's skilled engineers, it offers elevated levels of anti-magnetism and a five-day power reserve, and comes with a 10-year warranty and 10-year recommended service intervals.

The watch is available in three iterations with ceramic bezel insert featuring a bright, legible white diving scale on a base of black, navy blue, or deep forest green. The case back includes a sapphire display window to showcase the new in-house movement, and the watch is water resistant to 300 meters.

All three versions of the new Aquis Date Calibre 400 41.5 mm series use a sunburst dial finish. Buyers can choose between a dark anthracite gray tone, an oceanic sunburst blue, or an emerald green, which feels deep and intense in initial images. The in-house Calibre 400 automatic movement inside the Oris Aquis Date Calibre 400 41.5 mm series is a major step forward for the brand's movement-making capabilities, especially for its core offerings. 

In addition to outstanding accuracy, the Calibre 400 offers magnetic resistance of up to 2,250 gauss, more than 11 times the current ISO standard for anti-magnetism. Power reserve performance is robust as well, with twin mainspring barrels producing 120 hours of power reserve. 

Oris also validates the longevity of the Calibre 400 platform, recommending a service interval of 10 years rather than the more standard five recommended years between services. All three watches feature a stainless steel bracelet with vertically brushed center links. For those that prefer straps, all three models in the new line can also be optioned with the brand's signed textured black rubber strap, which also includes a folding clasp and dive extension for a modern and functional sporting look.
