I have recently bought a MuDu watch which I am really pleased with but cannot find definitive information about. The brand seems to be surrounded by stories of illegal importation and sales in Britain in the late 50's early 60's and I have seen some information on this forum.
Looking at Dr Ranfft's pages the closest I can get to the movement is AS1130 or Zenith2572. There appears to be a star symbol in a cloud under the wheel. I wonder if anybody could identify the movement. Also the coat of arms/ crest on the reverse of the case?
