I saw two marvels, recently. One is the 5500 with its superb guilt black glossy dial, from 1966: The other is a great 1016, from 1967. The tropical dial is very much my taste. Both, side by side. These Explorers are really charming. Best, Nicolas ...
Can the 5500 be considered as a real Explorer? Was it a somewhat lower entry point into the Rolex sports line? Would be cool to have something like this re-launched today
