Vintage Rolex bracelets, while wonderful to look at, simply never had the fit and finish of the end-links like their modern equivalents. Add 50 years of service to many of them and what you end up with is a very expensive, ill fitting, stretched out item in most cases. I was looking at a gen red 1680 a year ago with original bracelet-- it was practically unwearable. The endlinks were also quickly wearing away the serial number and case stampings.
