rmcsherry Posted June 2, 2008 Report Share Posted June 2, 2008 Does anybody know what the small wheel is that engages with the crown wheel on this movement? All of the reference material I have refers to the crown wheel, ratchet wheel and click - but not the smallest gear (which seems to be pretty much unique to this movement, perhaps it is due to sharing the same components as an alarm movement?) Any help would be appreciated - I'm ideally looking for a Swiss part / Bestfit reference or term. Cheers. Link to comment Share on other sites More sharing options...
POTR Posted June 2, 2008 Report Share Posted June 2, 2008 oooooo Angelus 240... I wonder what project you have in mind... I would call it an intermediate wheel, or intermediate coupler wheel... as it appears to be in line with and therefore a part of the keyless works... probably between the castle wheel and the transmission wheel, possibly designed a bit differently to be more sturdy to help transfer power to the stronger mainspring without damage... but I can't be sure, as every one of these movements I bid on seems to go way out of my price range for some strange reason ... so, I never got to "tear into" one... and I have never seen a diagram or chart on this 'rare' movement either...

rmcsherry Posted June 3, 2008 Author Report Share Posted June 3, 2008 Thanks for your help. I have also checked with a watch-material house / watchsmith, who is unable to identify it from the photos - as you say, it seems to interact with the clutch so presumably there may be another gear hiding in there?! I think I may end up getting a watchmaker to photograph all of the parts whilst this one is being serviced; I've already created 3D representations of all of the other parts by ripping a key-wound movement apart!

POTR Posted June 3, 2008 Report Share Posted June 3, 2008 Serviced? As in complete? With a spankin' new engraved 3/4 plate without that alarm gear hole? Link to comment Share on other sites More sharing options...
rmcsherry Posted June 3, 2008 Author Report Share Posted June 3, 2008 That's the one! This one was mine, but it's now gone to another member - and been replaced by two more!! They've not been cheap to acquire, but should make for a pretty good project. Link to comment Share on other sites More sharing options...
