Professional Explorer (1963)
This model is almost the same as the later 1975 model except that the movement was updated to the 1570, which includes a hacking feature.
A rare watch originally designed for "explorers" as a tool watch but now the modern day version is more of an entry level watch into the Rolex Professional series range.
