The watch you are looking at is the Rolex reference 6062, also known as the Rolex triple-date moonphase, or one of the most complex watches to ever bear the mighty crown on the dial. It was produced from 1948-1953 in only 500 examples.
The pre-sale estimate on this triple-date moonphase is $150,000-$200,000 and it will be sold this Friday via Christie's New York.
