OK..can someone explain "jewels"...
I've been reading how my Sub-No date has more jewels than a regular Sub Date.
Because it has no-date thus fewer mechanical parts it does have more "jewels". OK, what do jewels actually do and how is the total # of jewels derived? Please forgive my ignorance here

Jewels, specifically synthetic rubies, are bearings against which shafts rotate. For more detailed info, click this link:

Yep. The more we all read and research, the more knowledge we all have to share.

It was after the introduction of the 14060M model that the number of jewels are now the same, i.e. 31. Jewels act as "ball bearings" in the movement and are localised between the moving parts. They are actually synthetic rubies and act as friction bearers to reduce wear and tear between the numerous moving parts. In a Rolex all 31 jewels are FUNCTIONAL. Some watch manufacturers use the number of Jewels as a marketing ploy - so a buyer thinks the more the jewels the better the watch - which is all BS. The actual FUNCTIONAL jewels in a watch are all that really matter. The rest, if any, are redundant!! JJ

Usually rubies used at the moving pivot points in the movement.
