Blancpain Fifty Fathoms Automatique 42.3mm Mens Watch Black

Ref. 5010-12B30-B64B

The 42.3mm case is machined from grade 23 titanium — a satin-brushed alloy with lower oxygen, nitrogen and iron content than the more common grade 5, giving it improved ductility and fracture toughness. At 14.3mm thick with a lug-to-lug span of around 48mm, it sits close to the wrist without bulk. The sunburst black dial carries Arabic numerals alongside baton indices, with a power reserve indicator among the functions. Calibre 1315 is an in-house automatic delivering a five-day power reserve. The bezel is unidirectional with a sapphire crystal inlay, and a further sapphire crystal covers an open caseback. The black rubber strap fastens with a titanium folding clasp. Water resistance is rated to 300 metres.
