In 2000 I purchased an "authentic" Tag Heuer Ladies watch for $460 at Costco. The Watch came with all the documents and I still have the original receipt. However, I took it to get a battery and the watch man say's it's a fake! I called Tag corp., gave them serial number & description, they indicated it may be a fake due to the crown supposed to be a threaded and mine is a push pull, they do not make AUTHENTIC push pulls, and for me to take it to Costco. I went yesterday, to Costco and they are willing to give me my $460 back, but to replace that watch today as it went up in value had it been real would cost approx $1,500. 00 is there something I can do?? I am befuddled to say the least.
