Hello,
I just purchased a Maxi Marine Diver from a watch dealer in eBay. He has a really good reputation based on reviews and has been selling expensive watches for quite some time. He purchased the Maxi Marine Diver from an Authorized Dealer in California. I received everything: box, authenticity card, cosc certificate, manuals, and etc. The watch and all the included stuff looks very authentic.
Just out of curiosity, what do I have to look out for to spot a fake?
