Blancpain Air Command

Blancpain's Air Command AC02 36B40 63B is a chronograph housed in a 42.5 mm red gold case. The case measures 13.7 mm thick, with a lug width of 22 mm suited to the calfskin strap. A sapphire crystal covers the sunburst blue dial. Inside is the self-winding calibre F388B, good for a 50 hour power reserve. The watch pairs a flyback chronograph with a tachymeter scale and small seconds, laid out for quick timing readings. The calf leather strap closes with a folding clasp. Blancpain rates the case to a modest 30 metres, enough for daily wear but not for diving.
