How to Check TAG Heuer Serial Numbersby Stephanie EllenUpdated July 21, 2017
Never purchase a TAG Heuer without a serial number; it is most likely a fake.
TAG Heuer is a Swiss maker of timepieces. It has been in business since 1860. TAG Heuer is the only watch manufacturer that offers timepieces accurate to 1/10th, 1/100th and 1/1000th of a second for watches, and to 1/10,000th of a second for other timepieces. Each TAG Heuer timepiece is stamped with a unique serial number. You can use the registration number to register your product with the company for service, or to find out your timepiece's history.
Locate the two numbers on the back of your watch. The top number is your watch's model number.
Find the bottom number. This is the serial number. It generally comprises two letters and four numbers. In some cases, however, it will be three letters and three numbers, or six numbers.
Visit Tag Heuer's website (see Resources) and locate an authorized retailer in your area.
Take the watch to your retailer, which will be able to authenticate your watch and tell you how old it is from the serial number.
