Hello Guys, I recently purchased a "Heuer Leonidas" watch from Ebay and need your input. I am new to Heuer but I discovered after purchase that Heuer and Leonidas did not merge until 1964. Seller says watch is from 1950's. However, this looks more like it's from the 1940's. Also the movement is stamped "Lenoidas" instead of Heuer. I believe Heuer watches after merging was stamped "Heuer." The dial has been definitely painted which I understand however, the watch needs to be authentic. The logo "Heuer" may have been painted to increase value and desirability. Not 100% sure but any expert opinion input would surely be appreciated. Anyone run into similar items? Thank you very much in advance.
