Here's something, found on a skip, now refurbished, and taking pride of place on the workshop wall.

I like it's industrial look...

I assume that these were installed in factories and were controlled by the same master clock as the clocking-in and clocking-out clock.

Would it be possible to synchronise to the VLF time sync signal (I believe the transmitter is at a place called Anhorn or something like that.)?

Wouldn't be very much different to this GPS version.

Hello Andy,
I had somebody come into my shop once with a BBC clock, which was along the lines of your project. The BBC clock also had a seconds hand. The customer wanted to keep the original mechanism, but was happy to have the pulses controlled by quartz.

We got there after a day or so of experimenting. The result worked well. We even had buttons to advance or retard the time. It was fun to watch those hands whizzing about 🙂
At the time, I didn't even think about doing a diagram for posterity!

I must say your solution is very elegant 🙂
I'm so jealous 😉

All the best,

Tony
