Either the watch is faulty, in which case you need to return it to the store which you bought it, Tag Heuer are very good at fixing their watches. If you bought it elsewhere, check that it is genuine, before sending it anywhere, because if not a genuine Tag Heuer, you may not get it back. I'm guessing its a Quartz model, which are difficult to repair but simple and cheap to replace, which is what they will do (Tag/Jewellers) if its an Automatic model, then it will be repaired quite quickly, as very simple to do.
