I check these older clocks with a 12v power source. It still seems weird to see the clock keep operating for a few minutes after I remove the power.

The VDO clocks made for Mercedes Benz between 1955 and 1972 were electro-mechanical. They still worked on spring power like a pocket watch but have short springs that were rewound every minute or so. The later models after 1965 could beat for five minutes on a rewind.
