Rinspeed exhibited its new concept car, the Budii, at the 2015 Geneva Motor Show. Carl F. Bucherer supported the innovative project run by Friend of the Brand Frank M. Rinderknecht with an exclusive, next-generation watch winder, a concept car designed to make driverless travel possible. The MANERO PowerReserve built by Carl F. Bucherer is mounted on the steering wheel. The status of the power reserve is monitored by video to ensure that the automatic clock never runs out of energy. When the display slips down into the red, the robotic arm of the steering wheel is engaged to function as a watch winder to recharge the power reserve. By helping to ensure that the driver is always on time, Budii proves to be a real "friend on wheels".
