We have always said: there are huge analogies between the luxury car industry and the watchmaking industry whether we are talking about marketing, sponsorships, typology of collectors. In terms of products, we can also find similarities. It is extremely common for cars now to have their middle-life facelift, and this happens more and more in watches. Not entirely a new model, however slightly different from the previous version, the Vacheron Constantin Traditionnelle Chronograph Perpetual Calendar goes through this process, with an improved movement (Calibre 1142QP) and a redesigned dial, becoming ref. 5000T.
