Today is Tourbillon Day, otherwise known as the anniversary of the day Abraham-Louis Breguet received the patent for his gravity-defying invention. During his lifetime, A-L Breguet created 35 watches featuring a tourbillon; as of 2018, there are less than 10 that still survive. This year, Breguet and the rest of the horological community are celebrating its 217th anniversary with a series of events and parties at the brand’s boutiques in Beverley Hills, Las Vegas, New York, Taipei, and Zurich. If you’re in one of those cities, pop in for cake, champagne, and the opportunity to view some of the brand’s novelties from the past few years, including this year’s Breguet Classique Tourbillon Extra-Plat Automatique 5367.
Released at Baselworld, the Breguet Classique Tourbillon Extra-Plat Automatique 5367 combines all the things we love about Breguet timepieces — such as the iconic Breguet numerals, a tourbillon, and an off-centered dial — with a heaping of new features for the Grande Complications collection. Technically, the Classique Tourbillon Extra-Plat has been in Breguet’s catalog since 2013, but this time around, a grand feu enamel dial is added and the power reserve indicator removed to create an increasingly austere dial layout.
The tourbillon that encompasses both four and five o’clock has a hand-beveled tourbillon bar topped by a spinel that stabilizes the extra-thin mechanism. The case comes in either 18k rose gold or platinum with a fluted caseband and exhibition caseback so you can see the hand-engraved bridges, barrel, and oscillating weight. It’s a surprisingly thin timepiece, coming in at a sylphlike 7.45 mm, thanks to the self-winding caliber 581 that is only 3 mm thick. The movement provides an 80-hour power reserve with a 4 Hz rate.
