Well, you did say that you finagled a fair price, so cost is relative I suppose.
The insert and pearl is obviously a replacement lumi, as is the crown. The bezel has a different cut than my original, so evidently that was changed as well. The hands, wow, not even close (although the second hand looks original).
Don't forget that even these transitional are really old, and parts do get replaced over the years. However, a buyer should be fully aware of obvious changes before attempting a purchase. After all, these things do cost a lot of money, and who do you want to have the edge, them, or you?
