Watchmaking has its singularities which convey the special connection a brand can, over time, develop with one model in particular. This is the case of Girard-Perregaux and its Tourbillon with three gold bridges. First presented by Constant Girard in 1867, it went on to distinction at the 1889 World's Fair in Paris. Reissued as a 20-piece limited edition in 1981, it is now the hallmark of Girard-Perregaux. Or, rather, its Gold Bridges with their immediately recognisable arrow shape. The brand has made them a badge, a means of identification for several of its watches. This Classic Bridges is the perfect example. Its two gold arrows instantly call to mind the brand to which they belong. This construction also makes it possible to create an opening onto the mechanisms at work.
