In the not too distant future, you'll be able to adjust your watch for Venus, Earth, Mars, or two dozen outer moons.

That's all? What about the sun?

It is useful to know when the local sunrise occurs, after all.

Hm. The stopped watch might be useful there too. Or maybe we just take the hands off the dial.

On the Sun, you can use a sundial.
