Hi all, A newcomer to the vintage watch scene because of a recent "hand-me-down" from my father. I believe everything is original, and the last service was probably more than 20 years ago... Last week I used PolyWatch to get rid of some of the scratches on the crystal. However, as you can see, there are two large cracks (4 and 6 o'clock positions). Through talking with few people, the general consensus is to have it serviced and cleaned up, but nothing else. In exchanging messages with a very reputable watchmaker, he suggested: "Movement cleaning and service, some interior parts if needed, replacement of all seals so in this case crystal, crown and gasket, refinish on the case and bracelet (if applicable)" Question: My goal is preservation and not total restoration. What should I have done to the watch and what not to do when sending this one in to get serviced? The case is pretty scratched up...but the chamfers on the lugs are still pretty well defined. Should I just live with the scratches and not "refinish the case" as suggested by the watchmaker? Thanks in advance.
