Breguet Héritage Phase de Lune 8860

Breguet's Héritage Phase de Lune 8860, reference 8860BB/11/386, has a tonneau-shaped white gold case measuring 35 mm in height. The case measures 9.7 mm thick, and its self-winding calibre 586 L provides 36 hours of power reserve. A sapphire crystal covers the mother-of-pearl dial, finished with hand-guilloché work. The dial carries a moon phase display and a power reserve indicator alongside central seconds. A calf leather strap closes with a white gold folding clasp. Breguet rates the case to 30 metres, which is modest but consistent with a dress watch of this kind.
