I was gifted a new Tag Heuer ladies watch quite a number of years ago, probably at least 15. I wore it only a few days while my other watch was being repaired. So it has been back in the original box all these years. I would like to sell it as I do not wear it but hesitate to do so in case it is fake. It did come from one of the jewellrey stores here but they also do not sell Tag Heuer anymore and have all had rumors of not being quite honest. So although the numbers are not one on top of the other but one on each of 2 sides. I am suspect but want to make sure. One number is WG1322-RO and looks original and the other number is RT8222 which looks a little bigger and not as deep engraved. How would one tell?
