The new Vacheron Constantin Traditionnelle Tourbillon Chronograph ref. 5100 sets the stage for a tourbillon placed at 12 o'clock and a monopusher chronograph, which pays tribute to the history of Haute Horlogerie and reflect Vacheron Constantin's technical mastery in the crafting of Grandes Complications. A complication single-handedly symbolizing the nobility of Haute Horlogerie. The “Etagé” case and lugs, a fluted case-back, a railway-type minute track, dauphine-type hours and minutes hands are some of the aesthetic codes of the Traditionnelle collection and all are clearly present on this new Traditionnelle Tourbillon Chronograph.
