Pcket watch "Art déco"?

[BlueHarp]

Same for me, but this is the first time I use the Bestfit. I understand that, for a 17-3/4 caliber, I have to consult page 150, but I can't find any resemblance.

Thank you for all your research. I learn a little more each time I use this forum

Last question: would you agree with me that this watch was probably made before WW2? I would say in the 1930s or 40s.

I've started trying to use the Betfit, but I don't know which measurement I must take for the caliber. The diameter of the dial side is 40mm, and the other side 36,5mm .

It would be the size of the plate.

I cant find it in my books, the setting lever spring is quite distinctive i couldnt find anything like it at all.

I can't find anything similar either.  All the writing on the case was a form of advertising, stem set, Swiss lever etc usually found on older watches.

Looked all over and I can't find it. Pity Ranfft movement identifier doesn't work.

The closest movements I've seen, from general layout, and shape of keyless are Corterbert.

I thought they were a close match to Cortebert, Nev also suggested Invar , i found a 19"' that had a very similar curved balance cock.  I looked at Revue as well but Ranfft was throwing up 404s on the pocket watch sizes.
