.....direct correspondence between Rolex and diver for one of my Patent Pending. I intend to do a review of both the watch and this documentation. The argument was put to me that the Mk1 Patent Pending was not a prototype watch because it was retailed with box and papers. Well, i know that one or two watches with Mk1 dials have been seen at retailers, BUT, here is one of my issues.... the Mk1 dial was issued in total number of, maybe, up to 300. Who, in their right mind at Rolex, would start a production run of 300 dials with the intention of being a commercial run? Here is another issue...we have solid documentation showing that Rolex were in discussion with divers about testing the Mk1 dial as a prototype watch that "needed" testing before Rolex were happy with its features. Why would such documentation have taken place "if" the watch was ready to retail?
