For the last year I have taken metalsmithing classes. The skills I have learned are for jewelrymaking but I think can cross over to making a case.
doming or dapping
setting a cabochon (flat stones which is simular to setting a crystal)
making false and real henge
I have not done any casting or lost wax art
I asked my instructor and she said I would first need to get some plans. I was thinging about 6497 or 6498 movement.
Any thing would be appreciated. Maybe to early 1900s wristwatch plans would work.
