Welcome to the Forum

Watch crystals of this type are replaced by size and not function due in part by the large number of case suppliers at the time. The only "standard" size was the movement. 18 size , 16 size and so on. Bezel diameters can vary widely, as can dome height.. ( for hand clearance )

There is an old thread in the Pocket Watch section that gets into the different size/type of watch crystals available.

Measure your Bezel and make a determination as to height and contact me here or any of the many sellers on Ebay with your requirements.
You may have to buy a " range " but most sellers will work with you if you explain problem.

I remember the first one I tried to figure out.
I was like what on earth is a lingue????
Weird French measurements.
I measured, converted and ordered. It didn't fit. Neither did attemp number two. The third one fit.
If you find a seller willing to accept returns give it a try. If not it might be cheaper to send your watch to someone competent to fit one.
If you decide you are going to become an addict just start buying lots of crystals now. Hahahaha
I have a decent assortment I have gathered. This way if I don't have one that fits it's much easier to narrow it down.
