Photo Report: Breguet Classique Tourbillon Extra Plat Automatique 5377 Platinum (live pics)

By Thierry Ané on June 7, 2014

When a brand named after the inventor of the tourbillon unveils its new take on the complication, expectations are necessarily high. With the Classique Tourbillon Extra Plat Automatique 5377 introduced last year in rose gold, Breguet did not disappoint as they managed to keep the visual appeal of Abraham-Louis’ original creations while endowing the movement with the latest watchmaking innovations. The presentation of a platinum rendition of this model at Baselworld 2014 gives me the opportunity to come back on this stunning piece of fine watchmaking.

Visually, this Tourbillon Extra Plat 5377 is faithful to the brand’s unmistakable aesthetic. The 42 mm platinum case features the thin and rounded bezel, the fluted caseband and the soldered lugs that have made the success of Breguet’s timepieces. The silvered gold dial is decorated with four different engine-turned patterns: the circular-brushed hours and minutes chapter presents a Clous de Paris centre and is surrounded by a barleycorn motif. The power reserve segment has received a straight chevron pattern and cross-hatching was used to outline each feature. The dial layout is also typical of the watches made in Abraham-Louis’ day: the time indication is off-centred and the power reserve indication and the tourbillon are positioned asymmetrically. Lastly, the flame-blued Breguet-style hands and the secret signature complete the Breguet look.

Behind this traditional appearance, the watch hides the extremely contemporary self-winding 581DR calibre. It is equipped with a silicon balance spring and an escapement with silicon and non-magnetic steel components. Its balance beats at the rather unusual 4 Hz frequency and still manages to provide 90 hours of power reserve thanks to a patented “high-energy” mainspring barrel. The tourbillon cage made of lightweight titanium is held by a modern-looking and extremely long straight bridge. Thanks to this ultra-thin movement (only 3 mm in height), this timepiece wins the enviable distinction of being the world’s thinnest automatic tourbillon watch (with a thickness of just 7 mm).

The sapphire exhibition case back lets you admire this extremely decorated calibre with 14 visible jewels (42 in total), beautiful hand-engraving and the platinum peripheral rotor. The watch is mounted on a black alligator strap secured by a traditional pin buckle made of platinum. All in all, this is an extremely elegant timepiece with a beautiful traditional aesthetic. It looks great on the wrist thanks to its modern 42 mm size and houses a very high-end contemporary movement. Whether you prefer the warmth of brown alligator and rose gold as with last year’s version or the restraint of platinum with black alligator, one thing is certain: you will end-up with an exceptional piece of fine watchmaking.
