Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5010 12B40 NAOA is a dive watch with a titanium case measuring 42.3 mm across. Case thickness comes to 14.3 mm, and the lug width runs to 21.5 mm. A sapphire crystal covers the sunburst blue dial, which carries a date window and a central seconds hand. The unidirectional rotating bezel allows for timing elapsed intervals underwater. Blancpain fits the case with its self-winding calibre 1315, good for a 120 hour power reserve. A textile NATO strap closes with a pin buckle. Rated to 300 metres, the case leaves plenty of margin for diving use.
