Re: Innovative sundials?

"To be fair, analogue watches don't work in the dark either."

Yes they do, they glow in the dark. Have done for a very long time.

Also there have been analogue watches that have a backlight around for long enough that you can buy one for your kid:

Here is another analogue watch that sets the time by itself from a radio broadcast powered by an atomic clock, this also lights up in the dark:

As that one too expensive? Here is one using Indeglo, a backlight trademark that came out in the 90's:

So yes, analogue watches work in the dark and have done so for a number of decades.
