Identifying a fake Tag Heuer watch is not always easy. Watch knock-offs are made all over the world. Cheaply made Japanese replicas are sometimes a bit easier to spot, but Swiss replicas can require a trip to the jeweller to determine whether they are genuine. The best line of defence is to buy from a licensed Tag Heuer dealer, but if you must buy a watch from an untrusted source, there are a few signs to look for.
Hold the watch in your hand. Take note of the weight and study the craftsmanship. Note the detail of the dial, hands and watch band.
Watch the movement of the hands. An authentic Tag Heuer will have a smooth movement of the second hand while cheap replicas will have a defined "tick." On an authentic watch, the second hand will appear to glide because the inner workings of the movement are actually ticking approximately eight times per second.
Look at the printing on the watch's dial. Authentic watches have crisp lettering. If the lettering on the watch looks blurred or carelessly printed, walk away.
Take the watch to a jewellery store. If you can't determine whether the watch is real or fake, ask a jeweller. He can look at the movements in far more detail.
The most important thing to listen to is your gut. If you have doubts regarding the authenticity of a Tag Heuer you're looking at, walk away. It's imperative to trust your jeweller and research the company you're buying from. Always use caution.
When approached on the street by someone carrying a box load of watches who swears to you that they are all real, walk away. It is highly unlikely that you are going to find a high quality watch for £13 on a street corner.
