Among the pieces produced by Constant Girard-Perregaux that led to the creation of the famous Tourbillon with three gold Bridges, a pocket-watch with three parallel nickel-plated bridges, made in the 1860s, was a precursor of his masterpiece. Awarded a first-class prize at Neuchâtel Observatory, this creation already displayed bridges aligned in parallel, but the use of gold and the final arrow-shaped appearance of the bridges were yet to come. The limited-edition Vintage 1945 Tourbillon with three gold Bridges celebrates this heritage with more modern lines. Its rhodium-plated skeleton bridges with their pure, contemporary geometry, are the fruit of meticulous preparation: they are first delicately hollowed then carefully hand-polished. It takes seven days to achieve a perfect finish, especially in all the interior angles. The Tourbillon is also the focus of special attention, with its 72 components that have to be perfectly assembled within a diameter of 12 millimetres.
The rectangular case also contributes to the distinctive character of this timepiece. Inspired by a watch made in Art Deco style in 1945, it has been redesigned by the Manufacture. The case, with its convex profile and discreetly matched crown, harmonises perfectly with the wrist. The case-back of this exceptional creation has a sapphire glass to reveal the superb Haute Horlogerie finish of the Calibre 9600C.
This outward appearance is underpinned by technical mastery exemplifying the comprehensive skills of Girard-Perregaux. The Vintage 1945 Tourbillon with three gold Bridges is equipped with an automatic calibre designed – thanks to the Manufacture’s patented platinum micro-rotor mechanism incorporated under the barrel – to show to full advantage the architecture of the movement, emblematic of the Brand.
