cool.. thats great to hear :)

my bf got his serviced a few years back at the Tag Heuer store. It took them 3 weeks in total to clean and change the crystal face. They had to obtain it from Switzerland cos only they had that type of crystal in stock.

We managed to find the receipt that he got when he first bought the watch. Apparently, the watch is dated 1981.. but that's all the info that we found out.
Anyway.. hope this helps a little :)
good luck with the search :)
