Breguet Classique Double Tourbillon 5349

Breguet's Classique Double Tourbillon 5349PT/2Y/9YV is a platinum piece measuring 50 mm across. The case stands 17.4 mm thick, with lugs set at 24 mm apart, and diamonds run along the lugs, the case band and the crown. Inside, the manual-winding calibre 588 drives two independent tourbillons linked by a differential gear, mounted on a central plate that completes a rotation every twelve hours, and offers 60 hours of power reserve. The silver dial is hand-guilloché and sits under a sapphire crystal, with a matching sapphire caseback showing off the movement's finishing. An alligator leather strap closes with a platinum folding clasp, itself set with diamonds. Water resistance is a modest 15 metres, enough for the occasional splash but no more.
