Quoted from docquest:

For my version I want the clock to become the bat signal being projected into the sky. Since this will no longer be a clock with numbers around it I need a new way to indicate the current jackpot value. I thought about going electronic with an LED type display but decided I’d prefer to keep it as mechanical is possible. The clock face is just a flat disc with a clock hand printed on it. In my case it will be replaced with a graphic of the bat signal symbol.

The display looks a little washed out in that video clip but it looks much better in person. The scrolling is also much less noticeable in person. This particular display has an aspect ratio of 1 so the video is a little squished.
