Yea I didn’t buy this watch from a independent seller so I’m not sure what to think of your so sure it’s fake
you can think anything you want, I guess. I can only give you information. I can't force you to drink.
Not sure why buying or not buying from an independent seller would matter, in regards to my determination tho. Unless you bought it from an AD, nothing else makes a difference here. The watch is an obvious fake. It's unfortunately as simple as that.
I didn't know much about watchfinder, so I assumed you were implying that watchfinder is selling watches, when you said they are a large corporation. So unless you bought it from them directly, from something they themselves own and sold, which I can't seem to find information about. you DID buy from an independent seller. This is no different than ebay or even amazon, in how products are sourced. The only good thing, is that they receive the watches prior to shipping them out. Which is scary, considering they let this watch go through their "highly trained, manufacturer-accredited watchmakers." .
But even than, ebay has a program sort of like that, but only for watches at a certain price point. But I can't tell from their website (watchfinder) if their accredited watch makers are in house, or like ebay, are outsourced to third parties. Because as I've shown multiple times on here, ebay's authentication program is compete garbage. Because they send them to watch stores that don't have specialized knowledge. I'd bet money, that they opened the case, and saw a calibre 5 movement, and or they searched the serial number, which came back as valid, and they said " yep, it's real".
Look through this thread. Modern clones literally use "oem" movements now. All the parts ( except crown/tube on tag heuer) are interchangeable with the OEM. So sending it to a company that has very little experience with modern clones, and even less experience with the specific individual models we are dealing with, is pointless. They handle probably 1000's different models from 100 different brands. There is NO way they can know the tells of every single model, and know the tells, that are now changing every 1-2 years..... for every single model they might ever have come through their shops.
