Hi All - Not sure if I am in the right place to post this (or if I am doing it correctly), can anyone give me some information on this watch. I think it is a Heuer 13.1. other then that I no nothing about it and there doesn't seem to be much info on the web. It is in perfect working order. I have attached a couple of photos. Many thanks Don.
You can find some information on it at http://www.onthedash.com/Guide/Master_Reference.php4 Under French made. Case ref was known as 13.1, 131 or 13-1. Because there are only 3 digits in this model number, it is more difficult to find examples on the web. From the late '70s. Manual wind 7765 movement. Try googling "vintage Heuer 131 7765". You should find more info.
