Just found on Chrono24 a Longines 7855 from the late 60s (according to the serial number) with the exact same printed logo on the dial as my Longines 4915 from the late 40s (look at the "I" of Longines and at the left wing, for instance).
Apparently done by the same redialer, or an "official" stamp from Longines used by different redialers?!
Does anyone have an idea how to solve that enigma?
cheers,
Giovanni
