Sweet Jeepers! These are some very peculiar buttons. I don't know if these are supposed to be imitating Saturn, but with the Bakelite rings wrapping around those nickel hemispheres, I've always referred to these as my Art Deco Saturn buttons. They're a little tarnished and slightly dented, but I love these ornamental curiosities just the same. Oddball buttons with cherry halos, they measure over an inch across.
