Breguet Classique Grande Complication Tourbillon Extra-Plat Automatique 5377 Watch

The Classique Tourbillon Extra-Plat Automatique from Breguet contains one of watchmaking's most spectacular inventions inside its platinum case: an off-centre tourbillon with titanium cage whose realisation is protected by several patents. Incorporating a silicon balance spring and an escapement in silicon and anti-magnetic steel, the 581DR calibre beats at a frequency of 4 Hz, a rarely achieved feat for this type of complication. Despite being one of the thinnest timepieces in the world, this automatic tourbillon delivers an impressive 90 hours of power reserve, thanks to a patented "high energy" barrel.
