My son in law helped me with an electrical issue on my race car, after we were done I told him I would build him a watch for helping me.
He was always interested and has always liked my Russian watches.
I let him pick out all the parts and I put it together for him. He really likes his 53 cased sidewinder I made him he hasn't ever had a mechanical watch before. I think It is even more special that his father in law assembled the watch just for him from the parts he picked out with my own two hands. I feel the whole experience has brought us both closer together.
