Introducing the new Oris Aquis Date Calibre 400

Oris is a brand we all dearly love for their down to earth watches that are of incredible value for money and fantastic quality. Furthermore the brand is among the most connected to its fans with regular digital and in person meetings (when possible), high social media connectivity and memorable charitable actions, such as their over ten year commitment to their change for the better campaign.

Among the several special edition watches dedicated to the increasing awareness of the oceans fragile state, we have seen quite a few Aquis Date special edition models. And while the model I am introducing to you today is also a special piece, it is not a limited edition, but a standard production model and its speciality is not a dedication to a certain event or greater cause. The Oris Aquis Date Calibre 400 is one of the brands core timepieces and with a design language that can be found throughout the brands dive watches.

And while the model itself is not new, its internals are and this makes the watch so special. As the name already suggests, it is powered by the brand's calibre 400. This movement is the current pinnacle of Oris movement development, boasting a 120 hour power reserve, -3/+5 seconds precision per day, significant anti-magnetic resistance and a 10 year extended warranty. I call this movement the current pinnacle of the brands watchmaking, as I believe that we will see even more advanced movements by them in the future, highlighting the research and development going into these pieces.

Even though I appreciate all of the movement's features, the strong anti-magnetism is especially appealing to me, as I am an electrical engineer by profession and my area of expertise (electric mobility) often gets me close to strong magnetic fields of EV engines. Therefore I prefer to wear anti magnetic watches, as it can always happen that I come too close to a magnetic field which could damage my timepiece. In order to prove that the new calibre 400 is truly anti-magnetic, it was exposed to a magnetic flux density of 2250 Gauss and didn't deviate by more than 10 seconds a day after the exposure. This achievement is especially incredible considering that the ISO 764 allows a deviation of up to 30 seconds per day after an exposure to 200 Gauss. Knowing that a watch powered by this movement is able to keep up with strong magnetic fields and still continue to display the time precisely is something I highly appreciate, especially in my area of work.

Being a true dive watch the Aquis Date Calibre 400 comes in a 41.5mm stainless steel case that can be worn by nearly everyone due to its universal size. With a 300m water resistance and a divers extension in the double secured folding clasp it is ready for a dive whenever you are. The crown screws down against the case to ensure its water resistance and offers a great tactile feel for precisely setting the time and date. To balance the sunray finished dial, which is available in green, blue and anthracite, the date window was placed at six o'clock and as little text as necessary was added to the dial. I highly appreciate this, considering there are watches out there that display texts of biblical lengths on their dials - keep it simple! In order to support the colors of the dials, Oris offers the dials with similarly colored ceramic bezels that will keep their shine and color indefinitely.

Previous generations of the Aquis Date featured a closed steel caseback, which is nothing wrong for a dive watch, but the new Calibre 400 is visible through a large sapphire crystal that allows the owner to admire the industrial finish of the movement. And while I personally don't need to see the movement of a watch (unless we're talking haute horology), I find the exhibition caseback a fitting feature to further highlight the nature of the brand's latest movement.
Earlier I mentioned that Oris watches offer an incredible amount of value for the money and the new Aquis Date Calibre 400 is no exception in that regard. Priced at 3000 euros it is hard to find a similarly priced timepiece that offers similar features. That said, kudos to Oris for creating another absolute hit!
