From about the year 2000 genuine 18ct Rolex parts featured the image of a Labrador-type dog with the other hallmark components. Seen close up, this dog is finely detailed and the stamp has real depth to it, allowing a genuine 3D representation of Fido's head. If you look really closely at a genuine one, you will even see a letter in the dog's ear, which denotes the Swiss Assay Office at which the part was stamped. Compare a real one with this fake, where the dog looks more like a cartoon St. Bernard! Make sure YOUR Rolex dealer stays ahead of the game as we do, or how can you trust him?
