Can any kind soul help me identify this movement.


Recommended Posts

It has the same keyless works as the 3rd from the left on the uploaded chart
but has a different movement number as the only other markings on it are

Brevets with a swiss cross.

The number 652
( which I think looking at the numbers on the chart which is from 1949 to 59 this might be pre that but of the same family listed there, which due to the similarity in the design of the keyless works seems logical.)
and also on the front the two numbers. 92 and 225.

Think I might have hooked a rare fish here as Vulcain are usually not a cheap brand and it has an inscription on the case back saying it was given to someone as a presentation which means that its usually not cheap.

Also what is odd and of note is that there are 3 smaller bridges, I have not been able to find a picture of another one like it on Google...

So any information gladly recieved and if anyone has a balance for one or one for sale as scrap, I would be very intrested.
Thanks in advance for your time.

did manage to find this that identifies it as a 652. But what I really want to know is are these in house Vulcain movements or made by someone else?

Although mine says 15 jewels on it rather than 16

    • Look carefully at the tube end?? It appears to me to have a fragment thread visible? Either that or a step just away from the end? I can imagine a chamfer, but a step seems odd - but I've never seen the tubes used on these.
    • This is a very valid point and a subtlety that I was unaware of until fairly recently, learning all the time, the video below explains this point well:  
    • You don't have to use his special tester. Any good multimeter would work.
    • Yes, it looks like GT Revue 30. Doctor, You can not replace escape wheel by the dimensions You listed. One needs to know much more things like number of leaves of the pinion and it's diameter, the position in high of the table and the pinion, the hight between the pivots, the exact pivots diameter... And then, even if suitable wheel is found, one will need to know how to adjust the pallets position correctly. Restoring antique movements is something different than replacing parts. In older movements parts are not interchangeable, this means spare parts do not exist. Here the case is different, but still escapement adjustment will be needed if a wheel from a donor is found. So may be it will be easier to restore the donor for You...Restoring antique movements usually means making of the parts needed and this requires knowlage and working on lathes skill. In this case repivoting of the wheel is the natural solution, but there is a long way that one must walk untill getting ready for such work.
    • I was looking at Essence of Renata, a chemical used a lot for cleaning hairsprings: "Specially prepared solution for degreasing watch and instrument components. Indispensable for degreasing hairsprings." Looking at the MSDS you can see this is just pure n-Heptane, so could be an option for those who don't want to use the chlorocarbons or hexane?     HF6013 - Horological Essence COSHH Safety Data Sheet Horological Essence_0.pdf
