Blancpain Fifty Fathoms Automatique

Blancpain's Fifty Fathoms Automatique 5010 3640 NAOA is a dive watch cased in red gold, measuring 42.3 mm across. The case stands 14.3 mm thick, with a lug width of 21.5 mm, and the sunburst blue dial sits under a sapphire crystal. Inside is the self-winding calibre 1315, offering a substantial 120 hours of power reserve. The dial keeps things functional with central seconds and a date window. Blancpain fits the piece to a NATO strap in textile, closed with a pin buckle. This is a watch built for depth as much as looks, and the case holds a 300 metre water resistance rating.
