It appears to be rather unchanged since the earlier devices.

http://www.centraltimeclock.com/security/watchclock.php (the brochure and manuals are interesting)

And an old one ( https://youtu.be/xwkIzphNFZY - annoying music)

Clock with a rotating piece of paper in it. When the key is turned, it alters (cuts / stamps) the paper.

The modern ones are modern made, but the design remains rather unchanged.
