Tonino Lamborghini Watch GT1 Blue T9GC. The GT1 quartz chronographs take their name from touring car models and are strongly inspired by the heritage of the brand. In fact, details like the sub dials strongly recall the speedometer of a car, while the START/STOP pushers of the chronograph are inspired by the sport cars acceleration and brake pedals, pure homage to the automotive and mechanical DNA of the Lamborghini family.
