I have a friend who acts as old father time on a vintage railway. I have rewound solenoids for his slave clocks (30,000 turns). 24V is used but all slaves are in series and a resistor is used to set a current. For a single slave I would think 6V would be ample.
I think you can get electronic master clocks and GPS receivers may be able to provide pulses at one per second or a 1Hz pulse could be obtained from a cheap quartz movement.
