Oris Introduces the Aquis Date Calibre 400 with New In-House Movement

In case you missed it, last week Swiss watchmaker Oris launched its latest in-house movement with the now much lauded Caliber 400. Today, the brand unveils the first timepiece to contain the new mechanism, the new Aquis Date Calibre 400. The new model uses the same design as previous standard Aquis Date models, while containing, as its name implies, the updated, in-house automatic movement.

This Aquis Date Calibre 400 release follows what will likely be a predictable release schedule, as Oris works to update many of its well-known and most appealing models with the new movement. However, that the brand chose the Aquis Date as its first model to update with the caliber indicates the watch’s importance and market popularity.

The Aquis Date Calibre 400 is a 43.5-mm steel dive watch with angled lugs that provide an integrated appearance with the triple link bracelet; screwed-in, flat edged crown guards; and a large screw-down crown. Surrounding the nonreflective-coated, domed sapphire crystal is a sturdy ceramic unidirectional bezel with a 60-minute diving scale, its turquoise blue color matching the gradient blue used on the dial.

That gradient dial, which the Aquis collection is possibly best identified by, has a simple white-printed minute ring on its outer edges punctuated by lume-filled applied markers for each hour. The only exception is at the bottom of the dial, with the subtle 6 o’clock date window from which the model partly draws its name. (This style of date display offers a slight contrast to the popular analog date models that Oris also offers.) Also on the dial is a small printed brand logo toward the top, and some dial descriptors towards the bottom, which include some of the new features the model includes as a result of the new movement. Two large hands emblematic of the Aquis collection sweep around the dial to show the hours and minutes while a lollipop-tipped pointer counts the seconds.

Inside the new model is the oft-mentioned Caliber 400, which among its various features includes a chronometer certification, extreme anti-magnetism, 120-hour (or 5-day) power reserve, and a 10-year extended warranty and service recommendation. The movement is protected via a sapphire caseback, which assists in providing this diver’s watch with a 300-meter water resistance.

The new Aquis Date Calibre 400 will be available in November 2020, with the brand set to retail the model at $3,500 on a steel bracelet, and $3,300 on a rubber strap.

  1. Oris really starting to do great things since the development of Calibre 110. An in-house movement in its Aquis flagship model is killer!
    Now please Oris introduce a 40mm model.

  2. This is a beautiful watch, indeed, with some great features. However, as a value proposition, compare it to the Tissot Seastar 1000 Powermatic 80 silicium, reviewed in the February 2020 WatchTime. The Tissot had amazing rate test results, superior to many COSC chronometers reviewed recently. It is 300m WR, and has an 80 hour power reserve. For $850, it costs about 25% of what the Oris does. I like the appearance of the Oris slightly better, but the watches are very similar in appearance.

  3. Good looking watch! Seems reasonably priced, but I think it is going to be hard to find and buy in the US…

    I have an Oris watch and love it. I was excited to hear of this new movement, but finding it in a dive watch configuration burst my balloon. What is it, that makes folks buy a dive configured watch and wear it with a dress suit? Folks, you don’t look like Bond at all. Buy a DRESS watch for dress clothes not a dive watch!

  6. What does it exactly mean when we are talking about Inhouse movement? Is really every part constructed and developed by ORIS, or do they use a much more tuned Sellita movement?

  7. To large! I understand the 400 caliber was developed in house but not built in house.

  8. I own an Aquis Date in blue and it’s a lovely watch. Really sturdy and well made. Main drawback is a terrible power reserve on the one I have. I think Oris offer a lot of value and I wish them well with this new movement. One thing, where is the red rotor?
