Movement Identification help

Hi all,

I'm new here.

I've been learning watch repair for approximately 2 years now with some help from a friend of mine who's not long retired.

i've had this JLC for some time now and haven't managed to find out the exact cal. I thought it was an older version of the 438cal/11LO. I found one almost exactly the same (I need an escapement wheel for mine) but it was thinner that the one I have so i can't figure it out.

if anyone has any ideas that would be great, and if anyone can suggest where I might find a suitable escapement wheel for this that would be really helpful.




thanks,

chris
