I heard about, that a well known french brand, which used this caliber more decades, buy back this treasures, restor this watches, and sell them one more time. (They tell the buyer that is vintage!).
1953, i am sure this is not right. This type of watches, mostly Platin, are older. I think, about 1930is correct. You see the two pics and the difference of the old and the new one. But htis new one, second pic , also is not from 1953, this is younger. What they think when to use blue srews, i dont know?
