So you've probably seen my previous post on the Autavia 1163. I purchased that watch because I'm now intrigued by vintage Heuer. I've caught the bug I guess you can say. Thanks to a buddy of mine who recently gifted me his Heuer ref 844 that he purchased new in 1981. I had no idea what it was until I started doing a little more research. I'm still a bit perplexed by which version this is because I've seen the version with the cathedral hour hand and I've seen this version (Mercedes hour hand). However I have not seen this version without the "Made in France" lettering at the 6'oclock. What do you guys think? Which version are we looking at here? I also told my buddy I would compensate him some money....he insists that I don't but I want to. What do you guys estimate the value as this watch sits? The watch is running about an hour fast per day so I believe it to be heavily magnetized and in desperate need of a service. It's never been serviced in 40 years.
