While this era of Blancpain is often told mostly as a story of marketing genius thanks to Biver and those catchy slogans, there was also some real watchmaking. Biver’s partner, Piguet, was the son of ebauche maker Frédéric Piguet. Together, Piguet and Biver put together a plan to create what we now call Blancpain’s “six masterpieces.” These were six mechanical watches with complications harkening back to the days of traditional Swiss watchmaking, days that many thought might never return after the quartz crisis: a complete calendar moonphase, ultra-thin, perpetual calendar, minute repeater, split-seconds chronograph, and flying tourbillon. All six masterpieces came in traditional, round, 34mm cases, and you’ll see them engraved with their production number on the caseback.
