A few weeks ago we saw the launch by Oris of its new Caliber 400 and in these days the launch of the brand’s first watch to use that same Caliber, the Oris Aquis Data Caliber 400. Although the common practice is different, this is, launch the watch first and only then talk about the movement, it should be noted here, that this new Caliber 400, is the first mechanical movement developed by the brand for almost 30 years, the last In-house movement produced dates back to the early 1980s and for that reason, the importance attributed to that movement.
This new watch is aligned with other models of the Aquis Date collection and in that sense at first glance we do not recognize major differences or profound changes at the aesthetic level, maintaining the 43.5 mm diameter of the stainless steel case, a thickness of 13.7 mm a little thinner as the standard Aquis Date, a beautiful and clean gradient blue dial with lume hours markers, a date window at six o’clock, hour and minute hands centre and a central seconds hand, a unidirectional ceramic bezel with 120 clicks, 300 m of water resistance, a signed crown at three o’clock with crown guards and a sapphire crystal screw case back. This new Oris Aquis Date Caliber 400 came on a bracelet with polished external links and with internal brushed links, with a quick bracelet change system.
Now let’s focus on the main feature of this watch, the internal movement Caliber 400, it came with an impressive 5 days or 120 hours of power reserve (and you can read that mention on the dial), a lot because of the two barrels and the extended mainsprings, anti-magnetic features including a silicon escape wheel and many other components (30 in total), which allows to hold up to 2,250 gauss, a very accurate movement that runs between -3 and +5 seconds a day, whose values are below defined by COSC certification (-4 / + 6 seconds per day) and 10-year warranty including service interval.
Final thoughts, what we liked most about this new Aquis, without a doubt that the movement, is a great advance, with it also came to a 10-year guarantee that gives even more confidence in the movement, another point in favour, but this common to the standard model, is the fact that he wears smaller than he is, largely because of the small and angular lugs. What we liked least, almost nothing, the fact that it only allows the use of the bracelet or rubber strap seems little to those who like to vary between Natos, leather, rubber straps or steel bracelet, however, it is what it is and whoever buys it knows for what goes. What we would like to see soon is this new movement also in a smaller case (39 or 40 mm) for those who have small wrists or who prefer to use a smaller size.
