I stopped bothering with searches outside North America. This does limit England and Australia and Switzerland. There is plenty of domestic stuff without having to wade through the spam from India and Spain, not to mention Finland which is a front for Russia. South America is like throwing darts in the dark. One really has to watch shipping fees as these are not refunded, so high ones are suspect.
I reported a few things, with little or no effect. I have not bothered much with feedback either. Has no meaning whatsoever. One can look at how often a seller sells an item.
I have a set of parts lot sellers whom I follow. Mostly looking for job lots. It often seems feast or famine for part job lots. Clutch wheels and winding pinions seem to be short at the moment. Sometimes it is third wheels, other times escape wheels. Takes a lot of patience. I keep getting 570 stuff as I mix the ref with 750 and 560 is what I need the most. Screws are also often in short supply.
Empty cases are a real PITA. These of course are the first part scrapped. It is maddening that replica cases sell for the same as genuine ones or are for cheap movements and do not fit the old movements. Missed the boat on the WatchCo thing.
Dials on the other hand are somewhat easy to make. Or so I have been speculating for the last 30 years. For many decades, there were legitimate dial repaint refinishers. So it is understandable that the markets would be flooded with such. With modern tech like laser engravers and other plotting devices I think we will see more and more of this. My guess is that there are those who want to get the maximum value for the least effort.
