ORIS AquisPro DATE Cal 400

Where was this watch ten years ago! 

Oris’s in-house movement technology which debuted in the AQUIS DATE CAL 400 is now showcased in the brand’s most hardcore of diver’s watches, the 49.5mm, black Titanium, ProDiver.

Only it isn’t called a ProDiver these days; it’s called an AquisPro but needless to see this is the diver’s model that is aimed squarely at professional divers such as those working in the offshore industries and of course the desk diver among us that like their watches to have a bit of clout to them. Anyway it was bound to happen, Oris has now started to roll out more models with their newly developed in-house Caliber 400 movement and the lucky recipient this time round is none other than the AquisPro Date. The Caliber 400 is the perfect engine for a serious diver’s watch as not only does it boast a high level of anti-magnetism, excellent accuracy when compared to a chronometer, a power-reserve of five-days but comes with a substantial 10-year guarantee.

Engineered with professional SAT (saturation) divers in mind, the AquisPro is a highly technical tool watch chosen by divers who work on complex engineering projects in helium-enriched environments hundreds of meters below the surface. 

Among its special features is Oris’s patented Rotation Safety System, known as RSS.

This exclusive Oris device, commissioned by the professional diving community, enables the wearer to adjust and lock the unidirectional rotating bezel into place. 

This means that during a dive they can read off remaining dive time with absolute certainty.

A chunky rubber grip makes it easy to operate, even when gloved, while a yellow and white minutes scale engraved into the scratch-resistant ceramic bezel insert delivers high levels of low-light legibility. 

The new ORIS AquisPro Date Cal 400 is available, now. It has an MSRP in Switzerland of 4’200CHF.

Thoughts? There’s no doubt this is a very cool piece of kit – black Titanium, professional diver’s features plus Oris diving tech, and powered by an in-house movement with a 10yr warranty.

However outside of being a working diving instrument, its hulking 49.5mm diameter might be a bit dated in the 2020s; would be so cool to see a mid-sized AquisPro at say 45/46mm.
