You are correct, it probably did not require a microprocessor.  I had this Micropython board that needed a home.  It has a real time clock built in so the whole thing was done with about 10 lines of code, which mostly consisted of setting the time.  I used the relay to pull the solenoid.  Neet clock, it cleaned up very well, best I can tell from the serial number, it was made in the 1920's.  It loses a minute every 3 or 4 months. ... tom, N3LLL

Is that a relay you're using to pulse the clock coils?

Me too, made a small microprocessor controller to run it.  Three buttons, 1 step ahead, 60 steps and skip a step. ... tom, N3LLL

One of my projects has been restoring these old International Business Machines secondary or slave clock mechanisms & getting them running.  Serial numbers indicate they were made between 1942 and 1943.  They were inspected, packaged and crated, apparently for storage, at the 829th Specialized Depot at Gadsden, Alabama, in July of 1945.  I thought it might be interesting to note the property stamp on them says:
PROPERTY -- AIR FORCE
UNITED STATES ARMY

From 1941 to 1947 there was an entity called "US Army Air Forces" that many people forget about.  During this period the US Army Air Corps was a division of the US Army Air Forces.  And the media often changed Forces to Force in their stories. 

I think sometimes this contributes to the confusion regarding Air Corps vs Air Force.
