Blancpain Bathyscaphe

Blancpain's Bathyscaphe 5000A 0140 NAOA is a dive watch with a 43.6 mm ceramic case. The case measures 13.8 mm thick and carries a unidirectional rotating bezel. A sapphire crystal covers the sunburst blue dial, which has a date window and central seconds. The self-winding calibre 1315 drives the watch, offering a 120 hour power reserve. This movement is visible only in specification, as the piece is built around durability rather than display. A textile strap in NATO style closes with a pin buckle, and the lug width measures 23 mm. Blancpain rates the case to 300 metres of water resistance.
