Hands-On With Breguet Classique Tourbillon Extra-Plat Automatique 5377 Watch
Previewed at Baselworld 2013, Breguet’s Classique Tourbillon extra-plat automatique returns to the stage nobly dressed in platinum. Its looks are matched by ingenuity, for this extra-thin watch houses one of the more spectacular horological inventions – an off-centred tourbillon of which the lightened titanium carriage carries a Swiss Breguet balance with a silicon balance spring, as well as a specially developed escapement. These technical features notably enable the balance of the calibre 581DR movement powering this Breguet Classique Watch Grande Complication to reach the frequency of 4Hz, which is high for a tourbillon balance. This does not imply any loss of power reserve, for the patented high-energy barrel keeps the reference 5377 going for up to 80 hours off the wrist. To keep the thickness of the movement down to 3 mm in a 7 mm-high case, Breguet designed a peripheral rotor in platinum, winding in both directions of spin. This technical achievement makes the reference 5377 the thinnest self-winding tourbillon currently on the market.
The stylistic features of the dial of this 42 mm platinum wristwatch include four different engine-turned patterns executed by hand as a mark of respect for the old traditions of supreme workmanship and flawless finish. The hours and minutes chapter is enhanced by a clou de Paris hobnail pattern edged by a barleycorn motif. The power-reserve indicator at 8:30 is decorated with engine-turned strait chevrons, while each element has a cross-hatched border. A blue sapphire set into the centre of the tourbillon bridge draws the eye to the hands> This new self-winding extra-thin Classique Grande Complication Tourbillon shows off its class as a pure Breguet mens watch creation, combining timeless styling and cutting-edge technology.
