Let me begin by saying that as with any great vintage Rolex, the legacy is as much about validation as it is discovery. You may think you've just uncovered the almighty vintage Rolex sport watch, but until the global thought-leaders agree a watch is real, it's just not. I know a few people that have learned that the hard way.

At this point, in 2015, I think it is fair to say that most people believe there is such a thing as a white dial reference 6542 GMT. After all, we know there was such a thing as an Albino Explorer and an Albino Daytona. The Explorer, when it came up for sale, broke $180,000, while the Daytona became the most expensive Rolex ever sold at auction. Though, frankly, if you ask me which I'd rather own, I'd pick the 6610.
