Doe anyone know the model for this watch? There are no model stamp and it is missing the original case back. It also has a damaged balance shaft.
Any info on the watch would be appreciated, I would like to know the model so i can look for a case back. I haven't seen a manual winding bubbleback, do they come manual or is this an incorrect movement for the case? Also any pointers on where to get a replacement balance shaft would be great. Can/should the balance shaft be repaired? Sorry for all the questions, i'm new to watch repairs.
