I'm sure you know how to start this clock. XD If you are struggling to see the time, click the button on the bottom left corner to zoom in to the face. Click the button on left if you want to turn on/off ticking. For chiming, same on the right. You cannot change the chime melody when the clock is chiming.
Inspired by Howard Miller. This grandfather clock was a tough one, so if I got something wrong, let me know and I'll make adjustments. HAC Dual-Chime Wall Clock is here: https://scratch.mit.edu/projects/1044431776/
