On the heels of Watches and Wonders Geneva, Breguet has revealed the brand new Quantième Perpétuel 7327, marking the debut of a brand new perpetual calendar from the storied watchmaker. In a season dominated by chronographs — Breguet has its personal something-something arising — it’s nice to see a brand new execution of essentially the most advanced of all calendar mechanisms, the perpetual calendar. This author is considerably biased in the direction of calendar issues, and to uneven dial layouts so the Breguet Quantième Perpétuel 7327 is a straight-up win. Collectors ought to observe that reference 7327 is a alternative for reference 5327, the Classique perpetual calendar that was a mainstay of that assortment. You can see from the format of shows on the dial that there’s a new calibre at work right here.
We start with the brand new automated calibre 502.3.P, which delivers a extremely uncommon retrograde date show (between 9 o’clock and 12 o’clock on the dial); that is the obvious signal that there’s a new motion right here, and is how we distinguished this mannequin. Oddly, Breguet didn’t lead with this data in its publicity supplies (we now have not seen it in individual), but that is exactly what collectors ought to be aware of. Basically, it makes reference 7327 an essential milestone for Breguet. The hairspring and anchor are in silicon, which is par for the course on the manufacture, and the escapement beats at 3Hz.
Significantly, the calibre is simply 4.5mm thick, permitting the case to return in at underneath 10mm — that is excellent to suit underneath a sleeve. Breguet trustworthy will recognise calibre 502.3.P as an evolution of the ultra-thin calibre 502 (and thus one other improve to the unique Frederique Piguet calibre 70, as reported by Watches by SJX), and the model says that the calendar mechanism was added as module. There are a complete of 294 elements in complete. The modular development is probably barely disappointing for purists who insist on built-in calibres, however we predict that reference 7327 ought to be judged on its total deserves (for the document, we’d like to see how the twenty first century Breguet manufacture would strategy engineering a perpetual calendar from the bottom up, significantly with reference to the 45-hour energy reserve, which is properly under up to date expectations).
While we now have not seen the watch within the steel, Breguet lists an impressive list of finishing arts right here, together with a round barleycorn motif (rose-engine handworked) on the oscillating weight, Geneva stripes on the bridges, and chamfered edges on many elements. A have a look at the actual calibre will reveal loads concerning the high quality and nature of the ending, however Breguet is actually on par with different manufacturers on the haute horlogerie degree.
Turning to the case and dial, observe the fluting on the case center and the straight lugs, each of that are Breguet staples. The 39mm watch is on the market in white gold and rose gold, however the dial and palms stay the identical in each. The palms are known as “Breguet” as a result of Abraham-Louis Breguet got here up with the design, however the model additionally prosaically refers to this fashion as “moon” tip palms. Overall, the 7327 could be very fetching, together with the replace to the moon part show (no extra smiling anthropomorphised moon), and the steadiness of the knowledge on the guilloche dial.
We have some questions concerning the match right here, given the fashion of lugs, and we’ll return to this story with updates as soon as we see the watch. Having mentioned that, in case you are available in the market for a particular perpetual calendar with a grand story, and have S$116,300 to spare (identical worth in both gold), the Quantième Perpétuel 7327 could be it.
