That watch is the Rado DiaStar. The DiaStar is probably the single most memorable vintage Rado watch – the company brought out the first one in 1962, the year of (among other things) the Cuban Missile Crisis, and the debut of Dr. No. At first glance it is very much a watch of its time – there were (and are) many different models, but the ur-DiaStar has an immediately recognizable shape. The case is oblog, framing a round dial, with a shield-like expanse of metal around the watch face.
The shield-like appearance is apropos, because the original DiaStar is nothing less than the world’s first scratch-proof watch
