It has been suggested we have a separate Vintage sales forum on WUS. The existing WUS Sales forums are quite active and I and many others have a very difficult time finding Vintage watches in them.
Since we are not going to get a separate forum, the solution is for sellers to use VINTAGE in the title and and buyers will be aided by searching for that word. If this is done, those of us are not looking for modern Invictas might actually be able to find Vintage Invictas, et. al.
Remember to follow the Sales Forum rules! For example, this is not an auction - selling prices must be posted. When an item is sold, add SOLD to the title and first line of the description. Do not try to discuss the watch by posting to the listing thread (use the PM (private mail) system for that). And do not remove the selling price after the piece is sold. (There are other rules. Read them before trying to use the forum.)
Hopefully this will get us most of what we need.
I note for the record there are a number of watch sales sites on the Internet besides WUS and eBay. WatchRecon is a specialized search engine that will find watches on most of them (including WUS). (They all suffer from this vintage/non-vintage problem.) It does not search Dr. Ranfft's sales site unfortunately. That site seems to be one of the best vintage dedicated sites. It is well worth a visit.
