Up for grabs is a Rolex Explorer 1
1.0 mil serial number circa 1964 production.
The caseback on this watch is stamped with S&L (Serpico Y Laino) and the dial was most likely double signed as well, but dial was replaced during service with a matte tritium dial at some point.
Very good vintage condition case with all visible numbers.
Dial is service tritium replacement with great yellow patina on on hands and plots.
Bracelet is a Rolex 7836 with A date code, 358 ends.
Caseback is original, stamped 1016 and dated 64 inside. Outside has the correct S&L stamps.
