Breguet Classique Double Tourbillon Quai de l'Horloge 5345

Breguet's Classique Double Tourbillon Quai de l'Horloge 5345 (5345BR/1S/5XU) is a rose gold watch measuring 46 mm across. The case stands 16.9 mm thick, with lugs set 23 mm apart, and holds a silver dial under a sapphire crystal. The manual-winding calibre 588N2 drives two independent tourbillons linked by a central differential, with the tourbillon bridge itself doubling as the hour hand and completing a rotation every twelve hours. Power reserve runs to 60 hours. A display back shows the finishing on the movement, including the engraving of Breguet's Quai de l'Horloge building. Central seconds round out the display. The watch is fitted to a rubber strap with a rose gold folding clasp, and that clasp secures a case rated to 16 metres of water resistance.
