Breguet Classique Tourbillon Extra-Plat Squelette 5395

Breguet's Classique Tourbillon Extra-Plat Squelette 5395BR/1S/9WU has a 41 mm rose gold case. The case measures 7.7 mm thick, with lugs set 21 mm apart, and the dial sits under a sapphire crystal. Inside is the self-winding calibre 581SQ, skeletonised and finished with hand engraving and guilloché work, running with 80 hours of power reserve. The tourbillon, mounted to compensate for the effects of gravity on the escapement, is visible through the openworked dial alongside a small seconds display. A sapphire caseback shows the movement's finishing from the reverse. The watch is fitted to an alligator leather strap with a rose gold folding clasp. Water resistance is a modest 30 metres, in keeping with a dress watch of this kind.
