WATCHES & WONDERS 2021: Oris AquisPro Date Caliber 400

Let’s go back a bit to last year. To this post, in fact.

Oris launched their new in-house Calibre 400, an automatic movement with enhanced anti-magnetic features and a power reserve of five days. Coming with a ten year warranty and ten year recommended service interval, it debuted in the Aquis Date.

As we noted at the time, Oris’ goal was to manufacture an automatic movement that was accurate, reliable, consistent, and able to withstand any of the unknown pressures the vicissitudes daily life may place on a watch.

They reduced torque in the mainspring to conserve power and put less pressure on parts. They developed a new wheel design into the gear train to improve efficiency (the new movement retains 85 per cent of the energy transferred from the mainspring, compared to 70 per cent for most calibres). Finally, they re-examined the rotor. Traditionally it sits on a ball bearing but they put it on a slide bearing and made it uni-directional rather than bi-directional. There are also twin barrels.

A new escapement was developed, silicon was been used for the anchor and escape wheel, and other non-ferrous materials for the axes that hold the balance wheel, escape wheel and anchor in place. It has over thirty anti-magnetic components.

Beating at 28,800 VPH, the Calibre 400 has a 120 hour power reserve and is anti-magnetic up to 2250 gauss.

Now we come to Watches & Wonders 2021, and a new edition of their AquisPro Date using the Calibre 400, an all-black piece that not only has this cool movement, but which is just a great looking piece.

The new watch is in a 49mm sized titanium case plated in black DLC. The case back is also titanium DLC. With a rubber grip around it, the bezel has a ceramic insert and yellow and white engraved minutes scale which are lumed. In addition to the rubber grip, another diving-related features is the patented Rotation Safety System, which lets the wearer to adjust and lock the unidirectional bezel into place during diving.

The black dial is simple in function and design, but with a discreet a wave pattern, and the applied indices and hands all have Super-LumiNova.

With a water resistance of 1000m, the AquisPro Date is not just a diving watch in name. It comes on a 26mm black rubber strap with a black DLC-plated titanium folding clasp that has the patented ‘Sliding Sledge Clasp’ extension and Oris Safety Anchor. The latter ensures that in the event the clasp is released unintentionally, two hooks grab the strap so the watch doesn’t fall off.

It is available this month with an RRP of AUD 6,200/ CHF 4,200.
