Hello, I am researching a Tag Heuer Autavia GMT that is my fathers. He is experiencing some dementia and the details of how he got it are fuzzy. He says he got it for High School graduation but he graduated in 1966. From my research I am thinking his watch is a 1970’s version. He maybe confused with college graduation in 1971. I am trying confirm a couple details on it if possible and snapped a quick pic of it. I won’t be in town for a few more weeks so getting the serial number will have to wait. I think it is a 1971-2 version. It has a smooth back. According to OnTheDash it would have had an MSRP of $129.50, can anyone confirm this for me? The MSRP at the time would help me figure if it was given to him by my grandmother or his uncle. I believe it also has the original bracelet as seen in the pics. Also any idea of a ballpark value now? I have seen a huge range from $3000-$15000 and of course understand condition is always key to value. I am not a watch guy and am learning as I go. No, I would never sell it. Thank you for any new information or confirmed information.
