I love Explorer. I am very happy to be able to find this 5501 Explorer in white dial from the late 1950s using cal 1530. It shall match nicely with the black dial 5501 Explorer. I was looking for the Rolex 5701 Explorer with date initially but the price was not right. I believe the demand of such transitional Explorer models will go up in the near future as collectors are getting interested in the evolution of the Explorer models, the Pre-Explorer watches as well as the dressed watch Explorer.
