a u mnie Panowie niesamowita niespodzianka z Alle... najprawdopodobniej (bazując na niskim numerze) Zenith z Besançon we Francji, fabryczki zamknietej w 1975. "The Zenith factory of Besançon was operating from 1923 and in 1930 (in full economic crisis) there were 65 people employed there.They worked side to side with the factory in Le Locle, producing only certain models and/or movements. The production in the French factory were stamped with their own serial numbers. Where as Zenith serial numbers are in the millions (both for the movements and on the back of the case), the" French" serial numbers didn't reach a million in the years 40-50. Still these are tens of thousands of pieces, made from 1923 until the closure in the years 1970. Besançon is near the Swiss border and has a great horological tradition. Still in 1930, there were 1134 people working in the sector.Besançon is also famous for the Besançon Observatory chronometer concours" Najciekawsze jest to że jest to cal 106-50-6... z datą ..o którym nic nigdzie nie znalazłem, nawet u Rossler
