This one is consistent with my renewed interest in the chronographs of the 1940's and 1950's (pre-Carrera and pre-Autavia). I am determined to do some research to try to figure out the correct reference numbers for these watches. This is difficult, without a comprehensive set of catalogs.

My best guess is that this one is Reference 2447, from the 1940's. It is powered by a Valjoux 72 movement; 13 ligne movement; so it is a close match to a chronograph shown in a catalog from 1945.

Special thanks to Par for agreeing to a very gentlemanly trade . . . actually, this one was the first satisfying trade of my entire watch collecting career!! In the end, we didn't negotiate or go back and forth about the values . . . I liked this old watch (which he had) . . . he liked one of my watches . . . so we swapped, straight up. Maybe Par will post a photo of the one that he received . . . it's a Heuer chronograph, but of a diferent period and look!!
