Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5007 12B40 NAOA is a dive watch cased in titanium at 38.2 mm. The case measures 12 mm thick, with a lug width of 19 mm. A unidirectional rotating bezel surrounds the sunburst blue dial, which shows the date and a central seconds hand. The self-winding calibre 1150 drives the watch, delivering a power reserve of 100 hours, well beyond the usual two or three days seen on most automatics. Sapphire covers the dial, keeping the blue sunburst finish visible in good light. Blancpain fits the piece to a NATO textile strap, closed with a simple pin buckle rather than a folding clasp. The titanium case holds a 300 metre water resistance rating, in keeping with its dive watch billing.
