Here's a couple of shots of a Venner version of a similar clock -a combined synchronous motor movement  and pendulum.

A friend of mine has it. It was used in a power station environment up until only a few years ago. He paid a lot of money to have it restored.   It is apparently quite rare.

Year ago we used to sell a quartz clock and a 60hz clock mounted on a panel for generator stations on small islands in the Caribbean.

This is the way it was done in the 1930's
