 Whoops... must have hit the wrong 'reply' button... this was ment as an answer to the question how many jewels does the ETA 2892-2 movement have?
....

The ETA 2892A2 --- a self winding mechanical movement with date as the only complication --- is probably the same as the ETA 2892-2 . This movement uses 21 jewels.  From what I am reading on the .net, this is about optimal for a mechnaical movement with self wind.

Full details at the following ETA site:
https://secure.eta.ch/CSP/DesktopDefault.aspx?tabindex=3&tabid=28

From what I can see, it is not generally true that ETA skimps on the use of jewels.

I guess my question is, if the pivot is not jeweled, what is it?  Glass as is suggested above?  Metal as in really old cheap watches?
