Junghans pocket watch with 470 movement
470A, 470B, 470C
Classification of the Swiss Watch Movements 1936
This is a F.E.F. 19''' 40H, Fabrique d'Ebauches de Fleurier SA. I assume that Junghans bought movements from Fleurier, marked them with 470 A, 470B and 470C and sold it as Junghans, but no evidence was found so far.
For clarification: the FEF 40B (b for french bas) is only 4.2 mm high, the FEF 40H (h for french haut) is 5.3 mm high.
470A 7 jewels
470B 15 jewels
470C 15 jewels,
