I read somewhere, long ago (how is that for being specific) that the basic watch (ie: non-chrono) needed only 17 jewels to cover all necessary friction points...that more were superfluous and basically for decoration and/or marketing!

So less jewels = loud ticker and wears out faster?

I have a watch with that movement that is ready to be cleaned, lubricated and recalibrated. If the watch is using mineral glass is the longevity of the movement any different than if it had lab created jewels? Thanks. John

Never seen that patch before. Snooper Poopers as in.... stumble around in the jungle, smoke, talk loud, cuss at every impediment and hope the gooks don't hit us? Been There, but the patch is cool, thought it was an air wing thing but Mike 3/4 slapped me between the eyes! S/F Don Rait Mike 2 Actual Oct '67- June '68 Are you a member of 3/4 Association?

I do not know if the ETA thing is a true statement, but, scientifically, yes, synthetic Sapphire is harder than mineral crystal so it will last longer, BUT, it is probably over such a long time period as to make it superfluous to the operation of the watch!

Somehow I got to a Sept. 19, 2006 note from pacificchrono. It would be too hard to translate, grunt to grunt talk. I thought I was on a current page. Interesting patch from Mike 3/4 Vietnam. Sorry

Reunion comming up in Savannah end of the month Don, that is not a patch; that is a challenge coin for the unit. Here is the patch:  Infantry company, official designation: Bandido Charlie. Historical lineage, Company C, 1st Battalion, 16th Infantry Regiment, 1st US Army Division via Company C, 5th Battalion, 60th Infantry Regiment, 9th Infantry Division. http://www.bandidocharlie.com Mech unit that also operated "leg", used primarily as a security and reaction force when I commanded it. Currently deployed in Al Asad, Iraq.

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? Last edited on Fri Jul 6th, 2007 04:09 pm by Eeeb |
