Quite a few bids on this fake "18K"/SS GMT posted by a 100% positive feedback seller. I bet his other Rolex (ladies DJ) is also fake. I'm not an expert on identifying fakes, so take a look! https://www.ebay.com/itm/Rolex-GMT-...for-Men-Stainless-18k-White-Gold/164031927014Purchases made through these links may earn this site a commission from the eBay Partner Network
Good job. Just for posterity it would be useful if in these type of situation the OP would post photos of said fakes. Might be useful as a reference or someone could learn (e.g. me ) from them.
I'm always grateful for posts like these. The irony, however, is that eBay gets a hefty commission on sales from its site while the watch community is consistently doing all the work of spotting the fakes.
