Blancpain Bathyscaphe

Blancpain's Bathyscaphe 5000 36S40 O52A is a 43 mm case in rose gold. The case measures 13.4 mm thick, with a lug width of 23 mm. Inside is the self-winding calibre 1315, a movement with a 120 hour power reserve. The sunburst blue dial sits under a sapphire crystal and shows a graduated finish that darkens toward the edges. Central seconds and a date display round out the functions. The watch is fitted to a sail-canvas strap closed with a pin buckle. Water resistance runs to 300 metres, a figure that places this dress-leaning diver firmly among genuine tool watches.
