Carl F. Bucherer supports latest project from Frank M. Rinderknecht for this year's Geneva Motor Show. Rinspeed will unveil its innovative new concept car, the driverless XchangE. This timepiece enables passengers to keep track of three different time zones at once. The watch is blue in color to match the car and embedded in a luxurious, engraved globe, which is probably also the most exclusive watch winder. When the car is idling, the sphere turns continuously, thus guaranteeing that the watch is always fully wound. Effectively, this makes the entire car a watch winder. The watch winder allows travelers to keep track of time even if their journey takes them through different time zones.
