Early 60’s Tudor Prince

[jps3b]

A workmate just inherited a watch from his father who passed. He doesn’t care about the worth because he will never sell it. However, he does want to get it service so he can wear it. He lives in San Diego but works in Los Angeles.

Is it better to find a trusted watch worker to service the time piece, or should he take it to RSC Beverly Hills. The watch is working after we wound it, but it began to lose time after the first day.

It appears to be a 34mm with acrylic crystal. We couldn’t find a reference number, but it says “stainless steel” on one side of the lug.

Thanks for any input.
