Click the flag to swing the pendulum and start the clock. If the clock stops working all of a sudden, click the keyholes on the face to wind them up. Strike is on the left, and time is on the right. Click the button on left if you want to turn on/off ticking. For chiming, same on the right.
Inspired by Gustav Becker. It's called a gnome clock because it is smaller than the original Gustav Becker regulators. And this thing has been refurbished! Kienzle Wall Clock 2 is here! https://scratch.mit.edu/projects/631684190/
