Going Pro: Testing the Oris AquisPro Date Calibre 400 | Features

Professional as in skilled — in the case of utility, not many trendy mechanical dive watches in the marketplace can compete with the brand new Oris AquisPro Date with the model’s in-house Caliber 400. We obtained our arms on the look ahead to an in-depth evaluation.

Evaluating the Oris AquisPro Date Calibre 400 to a daily dive watch could be very very like evaluating a completely outfitted skilled diver to a leisure scuba diver. When the going will get powerful, for instance, when laying a deep-sea cable or repairing a submerged pipeline, it’s a activity for the professional — the diver’s gear should stand up to increased pressures, provide most security and be straightforward to function.

Our check watch has all of those properties. With water resistance to a depth of 1,000 meters, the case can stand up to excessive stress. Each the dive-time bezel and the rubber strap are outfitted with patented security mechanisms. And all working parts, from the bezel to the crown to the clasp, are designed for wonderful user-friendliness.

A Strong Case
The very massive, 49.5-mm case is fabricated from DLC-coated titanium and stays water-proof to a depth of 1,000 meters, thus providing ample reserves for sport {and professional} divers in any scenario. The crown screws shut and is flanked by protectors that guard it in opposition to impacts. The graduated insert within the bezel is fabricated from scratch-resistant ceramic. Oris has anti-reflective coating utilized solely to the underside of the curved sapphire crystal, which ends up in two benefits. First, nothing however a diamond can scratch the crystal’s laborious higher floor, and second, the bluish shimmer that’s usually seen on a watch glass with anti-reflective coating on either side, which all the time seems a bit awkward on a black watch, doesn’t seem right here in any lighting scenario.

The curved, absolutely threaded caseback protects in opposition to penetration by water. The depth of the six grooves for the software that’s used to open the case exhibits simply how thick this screw-in caseback actually is. By the way, the again has a round scale for changing between ft and meters. That is an fascinating merchandise of further info, however the scale is troublesome to learn as a consequence of its small measurement and the deep black DLC coating.

The pure rubber strap has a security anchor and a safe folding clasp with a five-step quick- extension mechanism so as to add as much as 18 mm to the strap’s size.

Most Safety
For dive watches, it isn’t solely necessary to have a excessive diploma of water resistance, but in addition a bezel that may solely be turned counterclockwise. If the size turns into misaligned throughout a dive, for instance, as a result of the watch scrapes in opposition to the diver’s gear, then the bezel will present an extended interval than the period of time truly spent underwater. The diver will subsequently start returning to the floor sooner than deliberate however by no means later. One other efficient safeguard is using inner rotating rings, which could be fastened in place after setting by way of a further crown, thus making unintentional rotation unimaginable.

Oris combines each protecting measures in a patented mechanism known as the Rotation Security System. This association consists of a metallic ring that runs across the rotating bezel and has a grooved rubber coating. Whenever you pull this ring upward, it engages with the flank of the dive-time bezel so the bezel can now be reset to correspond with the minute hand. When you push the ring down once more, the bezel is locked in place to point out the specified time. The ring can nonetheless be turned, nevertheless it doesn’t carry the dive-time scale together with it.

The bezel is designed for diving security.

However what in the event you neglect to press the ring down earlier than a dive? You then nonetheless have the identical degree of security that’s supplied by a standard dive watch as a result of Oris has opted for a unidirectional rotating bezel, regardless of the security system.

The 2-colored execution of the bezel will also be seen at night time.

The protection side of an expert dive watch additionally features a helium-release valve, which our Oris mannequin has. It lets respiratory gases, which accumulate contained in the watch case throughout a number of days of operation in pressurized deep-sea chambers, escape safely when the watch and its wearer ascend inside a diving bell. This function prevents extra stress from increase contained in the case when the exterior stress drops, which in excessive conditions might trigger the watch crystal to crack or pop off.

However that’s on no account the tip of the story in the case of security. Because it has finished with the rotating bezel, Oris has additionally invented a intelligent and patented answer for the strap. The innovation is an arrowhead-shaped finish on the strap that can’t slip out of the clasp. This so-called “security anchor” comes into play when you’ve got not fully inserted the pin into the specified gap when adjusting the size of the strap and now have not correctly pressed the clasp shut. Admittedly, every of those errors is unlikely and each of them collectively are extremely unlikely, however because the saying goes, “Higher protected than sorry.”
Regardless of the security anchor, the strap could be opened fully, for instance, to learn the conversion scale on the caseback. To do that, merely squeeze the arrowhead-shaped finish of the strap and slide it out of the clasp.

The watch has a built-in helium escape valve.

Handy Operation
The clasp has different benefits that not solely enhance security, but in addition improve utility and luxury. The fundamental design as a folding clasp that opens on one facet with security pushers is enjoyable. The system impressed our editors, who regard it as the best and most dependable to make use of. There may be additionally a quick-release extension that has 5 steps so as to add a most of 18 mm, which implies that the strap could be lengthened whereas being worn and, with slightly ability, shortened whereas on the wrist afterward. Two further spherical push-pieces are used for this.

The handy operation continues with the massive, easy-to-grip, screw-down crown. The black DLC-coated crown was dimensioned to match the ample measurement of this wristwatch, which in itself ensures straightforward operation. Final however not least, the rotating bezel could be very straightforward to make use of. Rubber is a fabric with grip. Deep fluting on the ring additional improves the non-slip really feel.

The screw-down crown has a black DLC coating.

A Trendy Motion
One function of latest manufacture Calibre 400 would possibly hassle purists of mechanical timekeeping in on a regular basis use. When you pull the crown out to reset the time, the minute hand jumps again about one and a half minutes. We had already observed this phenomenon in a earlier Oris check, so it’s clearly a peculiarity of the brand new self-winding caliber. It’s not a severe flaw as a result of the hand stoically stays in place when the crown is pressed in once more. But when the watch has progressively gained a number of seconds over a number of weeks and also you need to eradicate the achieve by pulling out the crown, ready a second after which pushing it in once more, you’ll additionally need to set the minute hand again into the proper place. This resetting will probably be vital sometimes. Though our check watch gained solely 0.5 seconds per day on the timing machine, it gained between 2 and 9 seconds throughout our several-weeks-long sporting check.

Aside from the slight achieve of our check watch, the Oris Calibre 400 leaves nothing to be desired. The manufacture motion, which debuted in autumn 2020, presents a protracted energy reserve of 5 days, considerably elevated safety in opposition to magnetic fields and a protracted service interval of 10 years. Consistent with the latter level, Oris even presents a 10-year guarantee, however factors out that, particularly with divers’ watches, the water resistance must be examined yearly.

Large however not too Heavy
As a result of our check of the AquisPro Date Calibre 400 didn’t final 10 years and our watch wasn’t uncovered to robust magnetic fields from huge loudspeakers at concert events, which had been cancelled because of the coronavirus, the long-lasting energy reserve turned out to be the most important profit we noticed. It’s very handy to have the ability to take a watch off for a number of days and never need to reset it whenever you put it on once more.

You don’t need to take this watch off whereas showering or swimming, however you most likely received’t put on it at an official enterprise assembly or a gala event. No matter its sporty software watch look, its ample dimensions imply that it received’t match below the cuff of a gown shirt or the sleeve of a sweater. A diameter of 49.5 mm and a peak of 17.5 mm are something however petite, however this huge watch isn’t uncomfortably heavy as a result of the case is fabricated from light-weight titanium. Due to its comparatively low weight of 158 grams, this watch suits fairly nicely on the wrist and isn’t top-heavy. And if even the final gap within the strap and the narrowest step of the fast extension mechanism nonetheless go away the strap too lengthy, you may merely reduce a chunk off the rubber strap and reposition the clasp. Right here once more, the whole lot is nicely thought out and nothing is coincidental. In spite of everything, skilled divers desire to keep away from undesired coincidences.

The date seems in a window at 6 o’clock.
