Hi I have a Seiko 6139-6002 case and I'm trying to fit a 6139-8010 movement into it. But the dial holding ring seems to be the wrong diameter, to thick and will not fit into case.
Has anyone got a picture and sizes of the correct dial holding. Or maybe someone can sell me one?
In the worst case I can just pare the plastic ring to size.
Thanks in advance for any help.
