Swatch Diaphane Automatic question

[JediKnight86]

I've bought two of these for christmas gifts; one for my dad and one for me. On the back it says "21 jewels"... I'm guessing the movements are on jewels? Anyone want to give me some info on the use of these jewels, what they are, etc?

It refers to the amount of "stones" used as bearing in the critical pivot areas of a watch's mechanism. The stones are usually rubies.

ahh..so why are they used? the watch was only $140. it would seem that a watch containing 21 precious stones would be more...
