It seems to match up pretty well with the Valjoux 72, shown on the OnTheDash movements page (linked below), and it does have the "72" and Valjoux "R" under the balance wheel.
The Ed. Heuer markings and logo look kind of suspicious, and I am not certain about the "ZOA" marking. I wonder whether this was the marking for a movement that was delivered by Valjoux to Zodiac, rather than Heuer?? I will check some Zodiacs over the weekend to see whether they have this marking.
