Hi everyone. I am new here.
Please help me learn value and more of this item. It is from my mothers grandfather 1900s pocket watch
converted into a wrist watch and during conversion I think it got new dial MISALLA Swiss.
IRISA is unknown movement for me and appears to be unknown to many people also.
It is working and I would love to know more.. Any ideas ??
