Identify movement

[ftwizard]

I have a lancyl, ladies watch. The movement is a Langendorf, but has no calibre number that I can see. I need a stem and a balance (slim chance)

Can anyone identify the calibre for me please.

[oldhippy]

Could we have a close picture of the other side. Most movements can be identified by the plates and keyless work under the dial.

[ftwizard]

Of course, here you go.

It looks like an Amida movement. There is an id to the right of the minute wheel but I can't see a cal number, not with my eye site.

[ftwizard]

It's a Langendorf movement, but there's no cal number. I can't find it on Ranfitt either.

Here is a list of Langendorf movements.

I don't have time to do this for you right now, but if you request an account with Ernst Westphal, (https://www.ernst-westphal.de/en/component/users/ ) then in their documentation pages you can view a copy of the best fit catalogue. Here you will see movements pictured by ligne size showing the keyless works parts which you can use to identify the calibre.

The pages won't load on an iPad - but they will work on a PC.

Thanks for the info, but those pages don't load on my Apple iMac.

What diameter is the movement?

Just under 20mm

It's an unusual movement (to me anyway) in that the balance stem, acts directly on the escape wheel, so no pallet fork.

Doesn't work with Google Chrome or MS edge browser either it seems - only Internet Explorer.

Anyway, what you have there is a cylinder escapement.  A word of caution when working on these - never remove the balance without releasing the mainspring power otherwise you will unleash all the power through the train in a heartbeat (which is a bad thing).

Just under 20mm would make it 8.75 lignes

Attached is a screenshot of the bestfit page, which suggests you have an 861, 862, or 863... but from what I can find I think these were lever movements

At this stage I would be inclined to ask for professional help... John Senior (obsoletewatchandclockparts.co.uk) has parts for a 8.75 ligne cylinder escpaement Lanco movement (cal 116), but I can't find any info about that movement anywhere.  He may have some other old catalogues with images of these movements to help.

As you stated , This is a Langendorf movement , but I got curious about the factory symbol stamped on the movement , so I had to look it up .

 I am impressed with all the info provided by members Old Hippy , and StuartBaker104 with the small amount of clues to go by .

 

[oldhippy]

I'll take a guess its a pin pallet movement.   As Stuart has kindly pointed out its a 861,862 or 863.

[StuartBaker104]

Sorry... Not sure I made myself clear. Bestfit suggests it is an 861, 862, or 863, but that doesn't make sense.  I think those are lever movements and the pictures show a cylinder escapement. Hence my suggestion to find someone with some older catalogues... I'm thinking this is something from the 1920's...

Thanks. i appreciate all the input. 

I wonder if I could get it repaired. It has a broken balance pivot, and a broken stem. The stem I can sort myself, but the pivot is beyond my skill set.

[StuartBaker104]

Repairable? - probably yes if you can find someone who's interested

Worth it? -  my guess is it will be in excess of £150.

Can't do it yourself? - if you can find them, the pivots should be replaceable on a cylinder movement using special punches in a staking set.
