·@lindo thanks for the tip! You also happen to know a renowned eBay seller with a constellation collection?
I have bought seven vintage Constellations from Closer over the last few years - all different, as I wanted a representative group from the 50s and 60s, and he kept finding good examples. You need to keep a close eye on his inventory (pardon the pun) as the good ones sell fairly quickly.
Other Constellations have come from various eBay sources in Australia, Europe, UK and USA. In all cases I have found you need to apply due diligence to every single aspect of what is on offer. Even well established dealers can miss things, especially if they are acting as a broker for other people. For example, I once bought an unusually nice 1980s Manhattan Constellation auto chronometer from Closer which I found had a different serial number on the case to the one on the movement. He replaced it immediately and did not offer it elsewhere afterwards. My guess is that he did not realise the problem when he listed it, which is understandable when he has an inventory of 7000 watches.
Japanese dealers seem to have access to a lot of good watches. Their only drawback is that it is common for them to take out marks and scratches. I am not opposed to a light cleanup, but there is a fine line between that and a watch that just looks too shiny, or has its edges rounded.
I hope this helps.
