People are selling the old parts on ebay, in some cases claiming they're new. In some cases they replace parts that don`t really need replacing such as hands and crowns, often crowns can be reclaimed by fitting a new O ring but that's not the Omega way.
As Omega are hell-bent on preventing anyone getting hold of parts (even second hand stuff) I can see why they're not sending stuff back as they used to do. I don`t agree with people selling parts and claiming they're new, but I don`t see a problem if they're honest and they ask modest prices.
