Stainless steel case chronograph by Wittnauer-Longines, circa 1965. This was the watch that was tested by the NASA along with Rolex 6238 and Omega Speedmaster. This is the first version, with “Genève” on the dial. Later on a dial with “Professional Chronograph” under Wittnauer appeared on the market.
The watch is really in outstanding conditions. Unpolished case, unbelievable patina on blued hands and numerals. There is not much to say, just look at the photographs and enjoy!
The watch comes with a Wittnauer vintage box.
36mm without crown
