Chopard has unveiled the Mille Miglia GT XL Chrono Speed Black (Ref. 168459-3008) chronometer back in January 2008. Visually, it differs from the previous iterations only with the color of its massive case. However, while the original GT XL Chrono featured an unremarkable stainless steel body, this one uses a relatively new (well, at least it is new for the watchmaking industry) technology that allows the case to maintain its finish for the virtually whole lifespan of the device. User discretion is advised, but it is one of the most durable coatings available at today’s level of technology.
