Breguet Reine de Naples Phase de Lune 8909

Breguet's Reine de Naples Phase de Lune 8909 (8909BB/5D/J21) comes in an oval case measuring 38.5 mm in height, with a thickness of 10.1 mm, in white gold. The self-winding calibre 537 DRL2 runs at 3.5 Hz and offers 45 hours of power reserve, viewed through a sapphire case back. A sapphire crystal covers the mother-of-pearl dial, off-centre at 6 o'clock and set with diamonds along with the dial flange and crown. The moon phase and power reserve display share the dial with a central seconds hand. A white gold bracelet with a folding clasp, also in white gold, closes the piece. Breguet rates the case to 1.5 bar, or 15 metres.
