ruby

Answer 2

In the old days before electronic watches there were parts in the watch that were constantly moving. To let them move freely there were jewels put in above and below them to act as pivots. Since those jewels were wear resistant the moving parts would not tend to get stuck after a while. Expensive watches had jewels on all the moving parts. Cheaper ones had them just on the most important moving parts. Really cheap ones had none.

Now that watches have electronic oscillators that turn on digital numbers after a specific number of oscillations are counted there are no moving parts. Those watches by law usually say "zero jewels" even though they are extremely accurate.because no one bothered to update the law. They will say zero jewels even if the entire outside is encrusted with diamonds because there are none inside the watch mechanism.
