Good day all, Pictured is a UG "auto chronometre 28" watch I now dub an "unwanted heirloom" due to recent realizations about its purchasers and previous owner. Not knowing much about these findings, the watch company, or the brand's growing following, I wore the timepiece between 2010 and 2019, when the crown smoothed down to a crumpled stump. Nowadays, the watch runs for about two hours after being handled, and needless to say, is in dire need of cleaning/repair. (It's safe to assume since the watch's acquisition in 1964, it was probably worn for less than twenty accumulated years.) I found a local watch/clock shop 30 minutes away familiar with the brand and willing to service it. My intentions are to barter the watch for (what I'll call) a more tangible, liquid asset. My question - in short - is it worth it (based on the lack of frequency of this model), or is this dead weight, all the way? Sound off. Thanks in advance!
