Breguet Marine Haute Joaillerie 9509 Poseidonia

Breguet Marine Haute Joaillerie 9509 Poseidonia, reference 9509BB/5S/984, in white gold with a case diameter of 35.8 mm. The case measures 10.5 mm thick and the dial sits under a sapphire crystal with a sapphire case back visible beneath. Inside is the self-winding calibre 591 C, with 38 hours of power reserve. The mother-of-pearl dial is worked in guilloché and set with diamonds and coloured gemstones in an invisible setting depicting posidonia sea grass, with central seconds. A folding clasp in white gold, also gem-set, closes the alligator leather strap. Breguet rates the case to 1.5 bar, a reminder that this is a jewellery piece rather than a tool watch.
