Hans Wilsdorf Watch Model
Hans Walsdorf was the founder of Rolex, and from 1934 to 1940 he sold a line of watches with his name on the dial. Tommy Taylor sent in this photo recently of his Hans Wilsdorf model, which I just updated to The Hans Wilsdorf Story, which I highly recommend reading if you want to learn what makes Rolex tick.
