Girard-Perregaux Laureato Tourbillon With Three Bridges

Watchmaking in levitation

In 1889, Girard-Perregaux presented its Tourbillon with three gold Bridges at the Universal Exhibition in Paris, and was crowned with a gold medal. Its new contemporary creation the Laureato Tourbillon with three Bridges has also inspired enthusiasm and admiration. Paying homage to its illustrious predecessor, the numbered, limited edition of 10 pieces houses a tourbillon with 72 components that performs one rotation per minute. Three translucent blue parallel bridges act as a beautiful audience for this spectacle and unveil the iconic architecture of a piece that is lighter than time itself.

Despite its complexity, the tourbillon successfully returns to the origins of watchmaking complications, which have been created by Girard-Perregaux for over 220 years. During the first half of the 19th century, the watchmaker Constant Girard-Perregaux carried out research in order to produce a high-quality tourbillon escapement. In 1860 its first incarnation won first prize at the Neuchâtel Observatory. It was fitted with a tourbillon movement and a barrel positioned under three parallel bridges. The three bridges then took the form of arrows and were made from gold. In 1889, Girard-Perregaux presented its Tourbillon with three gold Bridges at the Universal Exhibition in Paris, and was rewarded with a gold medal.

Steeped in history, the Laureato Tourbillon with three Bridges also draws its aesthetic origins from the style of the 1970s. Its strong, bold, contemporary design sets it apart from its peers. Its octagonal platinum bezel alternates satin-brushed and polished finishes to powerful effect. Its case-back, closed with six screws with a sapphire crystal, offers an extraordinary view of the movement. On the front, the guilloché circular mainplate is topped with sporty luminescent baton-shaped hands that impose their assertive character in this area entirely dedicated to transparency.
