Blancpain Bathyscaphe

Blancpain's Bathyscaphe 5100 1140 NAOA is a steel dive watch with a 38 mm case. The case measures 10.8 mm thick, with a 20 mm lug width, and the sapphire crystal covers a sunburst blue dial. Inside is the self-winding calibre 1150, which stores 100 hours of power reserve. Central seconds and a date function round out the display. The watch is fitted on a textile strap with a pin buckle. This is a compact take on the Bathyscaphe, sized between the standard sports model and the smaller references. Water resistance reaches 300 metres, unusual for a case this size.
