Hi Guys

i am struggling to find the reference for a watch movement - I need to try and source a stem for it so I can give the watch to my wife.

i think it's 1920 - 1930's, but that's a guess because the movement has a Ebauche Trust logo on it as well as the AS logo, it measures 10.5 ligne (just shy of 24mm)

i have looked for ages  on ranfft as well as Google. It has 416.9 on it as well, but I am beginning to believe this does not relate to the caliber

its a very pretty watch with a silver case, with a gold telephone style dial

thanks

dan

I am 100% sure as the drawing is not that clear but looking at my "bestfit" book it could be caliber 922. There is no caliber 416.9.

Thank you

novice question follows:

If they had a movement and moved the parts around, (move the balance from 6pm to 3pm against the crown position) - would this be the same calibre?

the answer to this question could make identifying movements a lot harder

thank you all for your time.

Ok, I give up, quiz over, you can tell us now!

I understand why clockboy went for the 922, but this appears to be a cylinder movement.

Ernst Westphal has a great selection of vintage catalogues, including one that shows pages of 10.5'" rocker bar cylinder movements all together, but I can't spot this one anywhere.

AS movements in this category are 175, 467, 740, 760, 937, 960, 1086

My advice would be to look at the drawings for AS on windingstems.com and pick the one that appears to be the closest fit to the other parts you have

You may be able to find some older movement catalogues, but yours definitely isn't in any of the ones I know of on-line

Have you search here? The 437 looks like it could be close? 

https://watch-wiki.org/index.php?title=Kategorie:Bildgalerie_Uhrwerke_Adolph_Schild_S.A.

Yes I agree thank you, it certainly does appear to be close

it makes me wonder that if the numbers jump between calibres if there are models in between that are not listed but closely related

appreciate your help my friend

Think there could very well be a model with that number. AS 416.9 but it's not easy to find them on google? Even the prima primarosa is close? 

But from there to find a stem that works? Maybe it would be easier to measure the clutch wheel and the movement plate and from there try to find a stem that could fit? If you go to windingstem.com you can type in the measurements and see if there is a stem available?

Interesting - windingstems.com lists an AS415 as being a calibre

Strange that "Bestfit" does not have the 416. Also cousins also do not recognise the 416. Personally if it was me I would just purchase a stem for the caliber 922 from Cousins which is approx. £5.

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
