here we go again

another non-timex, but i'm lookin' for any info available on this stubborn old girl (in french watches are feminin).




a friend gave me a box of old, dirty, oily, rusty, broken and good parts for pocket and wrist watches when i asked if he had any spares for my waltham traveller. even a couple chain-driven movements. i fixed the waltham, then dropped it on my workbench and broke it again. only runs face down. two years later, three days ago, i dug through the box, that had been literally kicking around in my son's room, looking for a screw and found this watch that i'd ignored the first time. no crystal, discolored dial, the case has been repaired and is broken at one corner and cracked around the stem hole, missing the original crown and stem (i found one that winds it and another that sets the hands), it was covered with gunk, dust, dirt and rust, so naturally i decided to take a look. the blued hands cleaned up easily, as did the case. i put a little oil on a couple teeth of the escape wheel and she took off and is keeping perfect time. go figure. now i'm wondering if there's a way to identify it and give it an approximate age. 27x29, excluding the lugs. thanks, tim
