This is a fine old Rolex reference 6694 with calibre 1210 from the early 60:s. The watch was in pretty good shape but didn´t keep the time so good anylonger and the winding never did stop. The friction in cannon pinion (hand setting mechanism) was also worn out and very loose in setting of the hands. That was the main reason why this watch lost minutes per hour. So a service with new mainspring, crystal and gaskets was done.
