Hello! Believe it or not, I have just found a watch that was missing for the last 21 years. It belonged to my grandfather, and it was very upsetting to my family when it got lost. Now that it's been relocated, I have a few questions about it I was hoping the community could help me out with. First of all, in my excitement at finding it I wound it up a bit. Later I realized that it hasn't been touched for the last 30 years since my grandfather died and it may not be wise to wind it until it's been looked at or serviced by a watchmaker. Could I have damaged it?
I'm also wondering how to identify the model and how to value the watch. I know my grandfather bought it in the 1940's in Europe, but I don't know if it was new at the time. It seems to have no markings besides "International Watch Company" on the face, and "750" (18k I assume) imprinted on the clasp. I'm not sure of the proper way to open the back to see the mechanicals inside and if there are any other marks in there.
Also, is it ok to bring it to any watch repair person to buff the crystal, which has some scratches, and clean the gold - or does it need to be more of a specialist?
Thanks!
