Blancpain Bathyscaphe

Blancpain's Bathyscaphe 5100 1127 NAJA is a steel dive watch with a 38 mm case. The case measures 10.8 mm thick, with a lug width of 20 mm suited to the NATO strap fitted here. A sapphire crystal covers the white dial, which carries central seconds and a date window. Inside is the self-winding calibre 1150, an automatic movement with a power reserve of 100 hours. The strap is textile, in NATO style, closed with a pin buckle. Blancpain rates the case to 300 metres, in keeping with the Bathyscaphe's diving credentials.
