Well i have read a lot about the different movements but the thing about this movement was that it didn't have any stamps or color decorations and that's what made me uncertain
Thanks for the info thou, it helped me alot
Not sure what you mean about not having any stamps? Look at all the engravings on the winding bridge. [3135], auto winding etc etc. However if you're talking about not having any ETA stamps then all that says is that it's not a gen ETA movement.
