With current pricing for gen 62xx series (plexi-crystaled) Daytonas beginning around the $60k mark and skyrocketing up from there (Newman/Exotic-dialed 62xx Daytonas generally trade well in excess of $100k, with sales sometimes tipping the scales at a quarter mil' for nice steel examples), I think sating your niggling sliver of desire will be a costly meal indeed. But, on a more positive note, I can assure you that the feel of a properly assembled franken (with all user-accessible components of genuine Rolex manufacture) will match its 100% factory-made analog in every way but the feel of your wallet. Of course, today, many frankens at this level have become unobtanium for all but the well-heeled collector.
