You underestimate the number of idiots that lack common sense. Over the years, I've heard a few colleagues that were bragging about new Submariners they got for less than MSRP (we're talking 1000-1500$ here) from a guy on eBay because he needed funds and was desperate to sell. People not into this hobby think fakes look like canal street specials and don't bother further inspecting items that look close to what they saw online. Fortunately for them, the bank got them covered if they figure out it is a fake.
All too true. My watchmaker showed me a "real" Rolex a guy picked up for a steal on EBay at £1,500 because the guy needed funds in a hurry, It was actually a €70 DHGate special
There was damn all good about it at all
The guy who bought it was devastated when my watchmaker told him in no uncertain terms he was ripped off.
Same with another guy who picked up a 116523 for only €5,000. It was 15mm thick. I think that says it all
The reason I came here was to study Omegas so I would not get ripped off.
