My Tissot PR516 (1970s) has been returned to me after a complete restoration / repair. Cost £500, well above its value but it has sentimental value. One element of the repair was a dial restoration. Everything is fine but the dial is missing the distinctive "PR516" logo. The repairers have initially apologised but that's it. They have offered to restore the PR516 logo to the dial at a cost of £350. The original dial has been damaged beyond repair hence it was replaced Without that logo the watch, in my opinion, is almost now only worth scrap value. except to me Any thoughts etc. would be appreciated. Clearly I won't use that repairer again.
