The presentation of the first scratchproof watch in 1962 represented the start of Rado’s success story. Everything began when Rado chief designer at the time, Marc Lederrey, put forward a totally new idea. He was constantly irritated when gold and steel watches, which at the beginning looked beautiful, often showed scratches after only a few days and subsequently had to be polished frequently. Then, tungsten and titanium carbides were only known as extremely resistant materials in the field of high-tech production of special tools. “Making a watch out of this material - that would be the solution," said Lederrey. And Dr. Paul Lüthi, who was at that time the boss of Rado, gave the go-ahead for this development. The result: the first scratchproof watch in the world!
