Inherited my Dads old wristwatch. It is a Mido engraved on the back with his initials and gift date, his 13th birthday, April 1946. The back is roll marked or stamped with ANTI-CHOC, STAINLESS, WATERPROOF,AUTOMATIC arranged radially around the back I have discovered that Mido was a middle of the road Swiss watch company that is now part of the Swatch Group. I would like to get it running again, it appears to be in decent external condition although I am sure it is worn internally. How do I go about finding a craftsman who can work on it and rebuild it if need be? No meaningful monetary value but a lot of sentimental value. Thanks for any comments or suggestions.
