Breguet Classique Tourbillon 3757

Breguet's Classique Tourbillon 3757, reference 3757PT/1E/9V6, has a 39 mm platinum case. The case measures 10.3 mm thick, with lugs set 20 mm apart. A sapphire crystal covers the silver dial, which is hand-guilloché finished and displays central seconds and the date. The manual-winding calibre 558 QPT drives the watch, with a tourbillon regulator and 50 hours of power reserve. A sapphire caseback shows the movement's finishing. The dial matches an alligator leather strap fitted with a platinum folding clasp. Water resistance is modest: the case is rated to 30 metres.
