Case Clamps for Cal. 613

[Seb :)]

Hello everyone,

I have recently acquired the Calibre 613 and am fitting it into a case (132.019). However, I do not have any case clamps. I don't know which type I need, nor where to find them, as I am quite new to servicing watches - any help about the type required would be much appreciated.

Probably a 550.1911

My charts only go up to ca 611

Front loaders tend to use 550.1911s Jumbo cases tend to take 550.1974 variations are marked with a letter (a, b, c, or s)

Hey, thanks for your reply - that is really helpful. I was just wondering, how would you tell which variation is needed for a given case/calibre?

Research is probably the best way to learn the variations. Archives here especially in the watchmaking section have a wealth of information. It takes time and looking at a number of watches to see the subtle variations. There are a lot of movement photographs and case clamps are often visible.
