This is a rare Heuer Monaco watch from the 70's. Found with an incorrect movement. It is a Heuer movement and similar to the Cal 11 that was supposed to be installed. Not sure why this was done but it was in storage for many years and just discovered fairly recently. The case is very nice as well as the dial and crown and pushers. Of course it will have the typical wear for a watch this old. Runs fine with a wind. Not sure about the auto ability to keep it going. Comes with the original Heuer leather band as well as another aftermarket that fits well. Please ask all questions and i'll try to answer. We are Raremetals in Worcester Massachusetts
