This appears to be a plastic cased, one jewel, transistor switched, magnetic repulsion Balance Wheel Impulse Motor made by/for Bulova France under license from ATO. The body of the wall clock is a K&G Lunéville France faïence plate. It’s noteworthy that the K&G mark on the back of the plate was only used from 1880 to 1922, whereas, the transistor was invented in 1947. Add a Watch required me to put a Manufacture Year so I picked 1965. What I know is that transistors were invented in 1947 and the ubiquitous quartz movements became popular around 1980.
This is what I found on ATO.

With the help of Marga at infofaience.com, this was found. The example found here was licensed to JAZ and is listed as a pendulum movement. It was apparently available in their catalog from 1975 to 1976.
