Rado unveiled its iconic diving watch, the Captain Cook, in 1962. As the marketing campaign announced, “doctors, engineers, athletes, deep sea divers, racing car drivers... this is the watch for you.” It featured a pivoting anchor under the 12 o'clock mark – the first appearance of Rado's world-famous trade mark. The anchor was not just an aesthetic consideration. It was mounted on a lubricated ruby bearing behind the dial. When it stopped rotating freely, it indicated that the watch movement needed to be serviced.
