Oris Big Crown X1 Calculator Swiss Watches

Next month the independent Swiss watchmaking brand will officially present its new Oris Big Crown X1 Calculator (ref. 01 675 7648 4264-Set 5 23 77) automatic pilot’s watch. Featuring the traditional coin-shaped bezel and an easy to read dial, the watch doesn’t look particularly original, but still makes a very nice impression with its high build quality and attention to even the smallest details.




Well, I guess most of you have already noticed that the watch has a certain “Breitling” smell about it.

The source of the (not quite unpleasant) odor is, of course, the fluted bezel and the slide rule that makes the upcoming watch very much alike the legendary Navitimer and other aviator’s watches from the great “B.”

Can’t say that I like the similarities, but let’s get down to business.

According to official info, the watch will be supplied in an oversized 46 mm stainless steel case with attractive grey gunmetal PVD treatment. On an average wrist, this oversized monster takes almost all available space and the long lugs are clearly not helping to make the problem any less glaring. On the other hand, if you are looking particularly for this kind of effect, you may actually like this timekeeper since it, unlike many competitors, doesn’t look like it was artificially inflated: all elements of the case and dial look very proportional to each other.

The dial, while certainly overloaded with info, brilliantly performs its main function –telling time– thanks to a pair of huge hour and minute hands.

On the black background of the central part of the dial they look very contrast and literally strike the eye with white Superluminova.

Unfortunately, Oris still can’t afford an in-house caliber of its own and definitely doesn’t want to bother itself with buying “history” hand-wound chronograph movements, so they simply equipped the timekeeper with the tried and true ETA Valjoux 7750 ebauche.

The movement, which is only slightly decorated, is known for its reliability and serviceability, so the choice is very practical, if not original.

More than that, with a list price of $3950 USD, the watch is quite expensive, but the price is, at least partially, justified by the automatic caliber that the Swiss watchmaker used to power this watch: it is actually not that easy to find a watch that is animated by one of those legendary 775x workhorses instead of the usual combination of an inexpensive ETA (or Sellita) three-hander with an add-on complication model that not only makes the whole product more, well, complicated to service, but also makes it overall less reliable.
