Breguet Reine de Naples 8939

Breguet Reine de Naples 8939BB/6D/J49 has an oval white gold case measuring 38.5 mm in height. The case measures 10 mm thick, with lugs set 16 mm apart, and the mother-of-pearl dial sits under a sapphire crystal. The self-winding calibre 537/3 drives the watch with a 45-hour power reserve, and its workings are visible through a sapphire caseback. The dial is hand-guilloché, and the watch is set with diamonds. Central seconds appear off-centre on the silvered gold hours plate. A white gold folding clasp closes the strap. Breguet rates the case to 1.5 bar, a modest 15 metres suited to occasional splashes rather than submersion.
