Abhinav is an amateur watch collector, He visited Joyce's Vintage Watch Store Pty Ltd, where a beautiful Rolex Submariner watch was displayed in the shop window. Placed next to the watch was the following sign:

Awesome! Genuine Rolex Submariner! It comes with an offical certificate from the Swiss Horological Society. Valued over &8000, but available for $6000. A great BARGAIN: BUT BE QUICK!! It won't last long!!

Abhinav examined the watch. He could hardly believe his luck! It looked like a genuine Rolex, so he purchased the watch. Three months later, one of Abhinav's Friend told him about a flourishing trade in cheap fake Rolex watches. So Abhinav took his watch to an offical Rolex dealer in Sydney. Sadly for Abhinav, the watch proved to be a fake, a very good fake thatonly an expert could discover by examining inside the watch. Even the certificate was a fake.
