Breguet Classique Tourbillon Extra-Plat 5377

Breguet's Classique Tourbillon Extra-Plat 5377, reference 5377BR/12/9WU, is a rose gold watch measuring 41 mm across. The case stands just 7.1 mm thick, a result of Breguet's efforts to fit a slim automatic tourbillon movement into so shallow a profile. A sapphire crystal covers the silver guilloché dial, hand-finished in the Maison's traditional style, and a sapphire caseback allows a view of the movement. Inside is the self-winding calibre 581 DR, with an 80 hour power reserve. The dial carries an off-centred tourbillon along with a power reserve display and small seconds. An alligator leather strap closes with a rose gold folding clasp. Water resistance is rated to 30 metres.
