Chronométrie Ferdinand Berthoud unveils the “Œuvre d’Or” collection, a new artistic interpretation of its original creation, the Chronomètre FB 1. This model previously existed in two gold versions: white gold with titanium lugs (FB 1.1) and rose gold with black ceramic lugs (FB 1.2). The collection now welcomes two additional variations, reprising the precious metals of their predecessors, white gold (FB 1.1-2) and rose gold (FB 1.2-1) respectively, while adorning them with original decorations.
