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

Thanks - I must admit I am scratching my head, 

recently I have been quite good at tracking them down

i am still looking

AS 922 i think i have that movement somewhere? That is why i recognized it? Not sure there is a stem on it though? Will take a look?

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

Thanks Stuart - if I knew I would tell you :biggrin:

i will follow your advice, maybe send it in to Ranfft also

much appreciated

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?

Tread carefully... Not to say this won't fit but AS415 is a lever movement whereas yours is a cylinder movement. Also, Jules Borel lists a set bridge for this whereas you have a rocker bar.

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.

I found an old stem to fit eventually - it's not perfect but after servicing the watch it is ticking away nicely

    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
    • I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
    • No, I now realise it’s broken😥 ive looked for one online, but v. Expensive! im going to service as is, in the hope that  one turns up. Thank  you.
