Girard Perregaux ←
Very rarely do we see TRUE innovation in the watch industry. This watch is a breakthrough in the quest for constant force that was pursued by Breguet, Daniels, etc. They completely rethought how an escapement could work. The result is a silicon marvel that provides constant force throughout the week long power reserve.
This particular watch is in white gold which looks great when the escapement catches the light and shines blue and purple! Just back from service, as new and with warranty
