Hi,
and sorry for the delay.
I startet a few years ago with a 5513 with A2824. I changed the movement to ETA2783 (lowbeat similar to the gen).
All the watches on the pic are with vietnam cases (they are ready for gen movements).
The cases have correct engravings an serial between 1964-1977.
Two watches now have gen movements (1560/1570).
Most of the dails were lumed by myself. One is an original.
If you need some help feel to contact me.
best regards
Stephan
