In some cases ruby (corundum). The jewels you can see in watch movements are usually red/pink in color. The jewel bearings are used in mechanical movements for parts that have a lot of friction.

What gems are used in watches?
Precious stones like diamond, sapphire, ruby, and garnet were used in the moving parts of watches ever since the invention of jewel bearings in 1704. Sapphires crystals are also used in watch faces because their hardness makes them one of the most scratch-resistant types of watch glass material available.
Are more jewels in a watch better?
The more complicated a watch gets, the more jewels it requires for more lubrication and less friction when moving. Complicated watches don’t only fall on high-end or luxury watch brands such as Patek Philippe, Rolex, or Omega. A lot of them can also be found in mid-tier and even entry-level watches.
