I love the Rolex Explorer I. It's the little brother in the Rolex sports watch family, it was my first Rolex, and regularly it gets left out of the all the mega-Rolex hoopla that we so often see at auctions with rare versions of Daytonas, Subs, and GMT's bringing in big bucks. So, when we opened up the Christie's Geneva May catalog and saw the watch here, we knew we had to cover it. It is a seriously rare watch, and it happens to be an Explorer I.
