Breguet Reine de Naples 8939

Breguet's Reine de Naples 8939BB/6D/964 is an oval case in white gold measuring 38.5 mm in height. The case stands 10.1 mm thick, with lugs set 16 mm apart, and the caseback is sapphire, giving a view of the movement. Inside is the self-winding calibre 537/3, with 45 hours of power reserve. The mother-of-pearl dial is hand-guilloché and the watch is set with diamonds, with a central seconds hand marking the off-centred hours plate. A sapphire crystal covers the dial, and the watch is fitted to an alligator leather strap with a white gold folding clasp. Water resistance is modest at 15 metres, in keeping with its dress-watch character.
