Blancpain has designed and built all six masterpieces of the watchmaker’s art and fitted them in identical 950 platinum cases : the ultra-slim, the moon-phase calendar, the perpetual calendar, the split-second chronograph, the tourbillon with eight-day power reserve and the minute repeater that also strikes hours and quarters. Available together as a set in a presentation case, only 99 of which will ever be made. (BLANCPAIN “Platinum Masterpiece Collection”)
