Stuck on a watch movement AS


Danh

Recommended Posts

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

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?

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.

    • Now I'm completely confused, it would appear that the epilame  is oleophobic  as @Marc states: This oleophobic  behavior can be seen as beading of the droplet (as above) which stops the oil spreading which is supported by what we observe on treated/untreated cap stones (for example), but as @VWatchie states this should make the drops more mobile, and not less mobile which is the opposite of what we want. In fact this beading and high mobility are desirable properties in things like smart phone covers, see below.  I am fairly sure that epilame doesn't make the droplets more mobile, so maybe its a strange coating with dual properties that are both oleophobic and cohesive/adhesive resulting in low mobility?? This may explain the high price??  
    • The description there is exactly how it's done, and it's very well written!
    • Would it be correct to say that the stronger the mainspring, the thicker the oil should be? So for a fusee mainspring, should a thick grease be used?
    • I started on pocket watches as they are easier to work on than wristwatches. Many had gold cases, which is why there are so many movements for sale. I was always on the look out for cases, for as Nickelsilver says,  a 16s movement will fit any 16s case* (with tweaks to the stem). I also started hand winding mainsprings, before I had winders. It can be done without damage, but it's quite hard on the fingers.  But you can make homemade winders, see here      * some movements, eg "railroad grade", have a setting lever on the edge of the  dial at about the 1 -2 o'clock, so need a special case.
    • Ok, on your movement plate you can see a star wheel on the right, this is the silencer, if you rotate the hands by hand through each hour you will see that eventually it acts upon the cam which moves the lever and in turn lifts the lifting lever thus stopping the chimes and strike working.  What you need to do is get your clock to 11pm and also turn the star until the cam lifts the lever and stops the action. The star wheel has a small spring that gives it a positive action between each movement, so once at 11pm you can rotate the star wheel around by hand until it stops the action at 11pm. Hope this makes sense to you.
