Classique Tourbillon Extra-Plat 5377
This model integrates the slimmest Breguet automatic Tourbillon movement. On its exquisite guilloché dial, we discover the Maison’s traditional hands
The off-centred tourbillon has a light titanium cage that carrys a Breguet silicon balance spring. Moreover, the escapement has been created especially for this piece. These technical characteristics enable the balance spring to reach a frequency of 4 Hz, a high frequency for a Tourbillon balance spring. However, the power reserve has not been sacrificed, thanks to the patented high-energy barrel. The model 5377 has a power reserve of 80 hours. To be able to fit a 3 mm movement in a 7.1 mm case, Breguet developed a platinum oscillating weight located on the periphery of the calibre.
