Oris has just come out with their latest Aquis Date Calibre 400, a classic diver’s watch which houses their new in-house automatic calibre movement (hence, its name). Oris describes their new movement as “highly accurate, highly anti-magnetic, [and] ‘highly reliable” and it comes with all the guarantees to back it up. This ‘new standard’ Oris have set includes both a 10-year warranty to match its recommended service interval and a massive five-day power reserve to keep your wrist ticking daily. This power reserve ensures that even if you put the watch down for a day or two, it will still run properly without the need to “re-wind” it. This is all made possible through twin-barrel technology that utilizes an extended mainspring, with each barrel capable of storing two-and-a-half days of individual power.
Technically, the Oris Aquis Date Calibre 400 has a 43.50mm stainless steel case and comes with two options for straps: a classic metal bracelet and a sleek ‘Oris’ branded black rubber strap. Other than that, both watches are identical and feature a beautiful color-shifting blue face, starting at a lighter blue in its center and slowly dispersing into darker hues as it reaches the contrasting silver indices. Because it is a diver’s watch at heart, it is capable of 300m of water resistance. As mentioned earlier, the key highlight of this timepiece is its Calibre 400 movement, which contains 30 anti-magnetic components and surpasses the ISO 764 enhanced anti-magnetic standard. In addition, it contains a sturdier rotor system than those typically found in automatic watches. Instead of a ‘ball-bearing’ system, it utilizes an innovative ‘low-friction slide bearing’ system which makes it less susceptible to damage and breakage over time.
