The digial clock works!

There really wasn't much that needed to be done. There were a few lose connections on the lamps, but none needed replacing. The two pin mains power connector and dual fuses were replaced with a single fuse and 3 core flex. But it was running slow, this was fixed by cleaning out the gearbox with contact cleaner and replacing the oil.

The first video shows how the calendar mechanism advances and resets. The whole mechanism is driven by a single large solenoid that is activated every 12 hours.

The second video shows the time being set. The rotary switches on the control panel are turned to the correct time and the "reset" switch lifted. The time then advances, as show by the lamps, and stops at the required minutes. The hours keep advancing until the right hour is reached and the switch released.
