Hi, I wonder if anyone might be able to help me figure out the most
likely reason an old 1960's battery clock has stopped working.

The clock has an unusual battery powered movement so i can't just swap
it out for a more modern one. It's such a nice old retro design I
don't want to bin it either.

I have a link to a .jpg of the clock's circuit board below.

My first guess is that it is the capacitor but I am unsure how I would
go about testing this (I have a multimeter) or any of the other
components.

Runs off a single D cell battery, battery and contacts are fine.
