The Neo-Tourbillon with Three Bridges Skeleton is a natural extension of several Girard-Perregaux fundamentals. The first is the 1884 patent for a tourbillon with three bridges visible on the dial side, the principle underlying the “With Three Gold Bridges” architecture and unique signature of Girard-Perregaux fine watchmaking. The second is the skeleton working on this type of movement, that Girard-Perregaux has been practicing since 1998. The third stage was the birth in 2014 of the Neo Tourbillon with Three Bridges. The latter were not straight, flat or in gold, but instead arched, taut, rounded, openworked and black.
