Jack Heuer created the Carrera watch in 1963 in tribute to the famous Carrera Panamericana auto race widely considered the most dangerous in the world. Just as exciting as the race that inspired it, the watch broke traditional watchmaking rules and was the first chronograph specifically designed for professional drivers, but perfect for speeding down the open road or cruising through daily life thanks to a more simple, more elegant, more readable design. He broke the rules of watchmaking design and TAG Heuer has been blending fashion and function ever since. The Carrera celebrates the speed demons, the risk-takers and the dreamers who race against time and never slow down. Automatic Movement: Sometimes revealed through a sapphire crystal, our automatic movements endow each mechanical watch with precision and reliability. Entirely manufactured in Switzerland, our self-winding watches do not need to be wound if worn every day. The heart and soul of our watches, our TAG Heuer mechanical movements offer variable power reserves. Unfasten your watch one evening, and find it a few days later, still on time.
