Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique, reference 5007 3644A NABA, comes in a red gold case measuring 38.2 mm across. The case stands 12 mm thick, with a lug width of 19 mm. A sapphire crystal protects the mother-of-pearl dial, which carries a subtly graduated black gradient. This is a dive watch, and it retains a unidirectional rotating bezel along with central seconds. The self-winding calibre 1153 drives the watch and stores 100 hours of power reserve, a notably long figure for the category. Blancpain fits it to a NATO-style textile strap with a pin buckle. The case holds a 300 metre water resistance rating.
