I think you know how to start the clock and to turn on/off ticking/chiming. If you cannot see the time very well, you know what to do. There's a new feature currently being tested on this clock, if you click on the lever on the right that is held by that gold spiral, you'll see a chime being tested. Could this be a new refurbishment?
Inspired by the Bastelstube. Well, you can definitely see the movement of this clock if you zoom in! We see the Jundes Signal Clock/Slave Clock with Sneaking Second in this link: https://scratch.mit.edu/projects/1123421070/
