Pocket watch or stopwatch bezel?

[Cuda74]

Found this on a homesite. Didn't find anything to go along with it, internals, face, etc. I don't know what it's made of but fairly light material.
Anyone got a good idea other than a pocket watch bezel?
Thanks

If it is from a watch , I've never seen one like it. I'll look in my book tomorrow.

Are you are sure it isn't from a compass?

Could be a curtain ring, there would have been a small eyelet screwed into the hole if it is.

Mike,
Well anything is possible but it definitely has a recess so that it appears that something sat into it and it isn't solid round like a curtain ring. The hole in the top fitting makes me think a watch or similar, but that's why I posted it, no definite clue.
Thanks

My thought is that ffuries is correct and there was probably originally a inner ring of plastic or such to ride on the curtain rod. The inner concave area is shallow and would probably rule out it being any portion of a vintage watch.

Maybe the bezel from a 1920s car clock?
