The chronograph is a decidedly difficult complication to produce – that much we know. After all, up until about 15 years ago there were less than a handful of manually wound chronographs in existence. Another great tenet of watchmaking is that of the ultra-thin movement, a specialty practically owned these days but nobody but Piaget. It was last December that we caught a glimpse of a truly extraordinary timepiece – the Piaget Alitplano Chronograph – a manually wound, in-house chronograph with fly-back mechanism and GMT function that was only 8.24 mm thick. As of today, this incredible watch is in stores, and we thought it was worth revisiting this incredible piece by allowing Philippe Leopold-Metzger, Piaget’s global CEO, to explain it to you.
