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 problems, and to uneven dial layouts so the Breguet Quantième Perpétuel 7327 is a straight-up win. Collectors ought to word that reference 7327 is a alternative for reference 5327, the Classique perpetual calendar that was a mainstay of that assortment. You possibly 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 computerized 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 info in its publicity supplies (we now have not seen it in particular person), but that is exactly what collectors ought to be aware of. Principally, it makes reference 7327 an vital 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.
Considerably, the calibre is simply 4.5mm thick, permitting the case to come back in at beneath 10mm — that is good to suit beneath a sleeve. Breguet devoted 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 parts in complete. The modular development is probably barely disappointing for purists who insist on built-in calibres, however we predict that reference 7327 needs to be judged on its total deserves (for the report, we might like to see how the twenty first century Breguet manufacture would method engineering a perpetual calendar from the bottom up, notably with reference to the 45-hour energy reserve, which is effectively under modern expectations).
Whereas we now have not seen the watch within the metallic, Breguet lists an spectacular listing of ending 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 parts. A have a look at the true calibre will reveal so much in regards to the high quality and nature of the ending, however Breguet is definitely on par with different manufacturers on the haute horlogerie degree.
Turning to the case and dial, word the fluting on the case center and the straight lugs, each of that are Breguet staples. The 39mm watch is accessible in white gold and rose gold, however the dial and arms stay the identical in each. The arms are referred to as “Breguet” as a result of Abraham-Louis Breguet got here up with the design, however the model additionally prosaically refers to this type as “moon” tip arms. General, the 7327 may be very fetching, together with the replace to the moon part show (no extra smiling anthropomorphised moon), and the stability of the knowledge on the guilloche dial.
Now we have some questions in regards to the match right here, given the type of lugs, and we are going to return to this story with updates as soon as we see the watch. Having stated that, if you’re available in the market for a particular perpetual calendar with a grand story, and have S$116,300 to spare (similar value in both gold), the Quantième Perpétuel 7327 is perhaps it.
