Breguet Classique Tourbillon 5359

Breguet's Classique Tourbillon 5359, reference 5359BB/6B/9V6, has a round white gold case measuring 40.3 mm across. The case stands 9.4 mm thick, with lugs set 20 mm apart. A manual-winding calibre 558.1 drives the watch, offering 50 hours of power reserve and displaying small seconds alongside the tourbillon at the front. A date function is also included. The watch is set with diamonds, and the silver dial sits under a sapphire crystal, with a sapphire caseback revealing the finishing of the movement. It is fitted to an alligator leather strap with a white gold folding clasp. Water resistance is modest at 15 metres, so this is a watch for the dry.
