Blancpain Bathyscaphe

Blancpain's Bathyscaphe 5000 0153 NABA is a dive watch with a 43 mm ceramic case. The case measures 13.5 mm thick, and the lug width comes in at 23 mm. A sapphire crystal covers the sunburst green dial, which sits under a unidirectional rotating bezel with a matching green insert. The self-winding calibre 1315 drives the watch, with central seconds and a date display, and stores 120 hours of power reserve. A green NATO textile strap closes with a pin buckle. Rated to 300 metres, the case is built for real diving use rather than just the look of it.
