this is a rare Galco chronograph from the 1960s. Gallet watches for the US american market where branded Galco. The Gallet engraving on it´s valjoux 7733 bridge has been defaced for that cause as well. the 37mm steelcase seems to be unpolished and the inverted pands dial and the hands carry the original tritiumlume. It´s working perfectly in all functions and comes on a nice vintage steelbracelet.
