Breguet Reine de Naples Phase de Lune 9935

Breguet's Reine de Naples Phase de Lune 9935, reference 9935BH/5W/J40D0, comes in an oval rose gold case measuring 36.5 mm in height. The case measures 10.3 mm thick, with lugs set at 13.5 mm apart, and the mother-of-pearl dial sits under a sapphire crystal. Inside is the self-winding calibre 537L2, with a 45-hour power reserve, and the sapphire caseback shows off the finishing. The dial combines a central seconds display with a moon phase, and the watch is set with diamonds. A rose gold bracelet closes with a folding clasp in the same metal. This is a jewellery watch built on genuine horological complication rather than decoration alone. The case is rated to 30 metres of water resistance.
