Breguet Classique Tourbillon 3797

Breguet's Classique Tourbillon 3797, reference 3797BR/1E/9WU, is a rose gold watch measuring 41 mm across. The case stands 11.7 mm thick, with lugs set 21 mm apart. Sapphire crystal covers the guilloché dial, finished with a Clous de Paris pattern and paired with a sapphire display back. The manual-winding calibre 558 QP2 drives a perpetual calendar and small seconds display, plus a tourbillon at six o'clock, and stores 50 hours of power reserve. An alligator leather strap closes with a rose gold folding clasp. Breguet rates the case to 30 metres, modest for a piece built around finishing rather than diving.
