As soon as I got home, I had to dig my clock out after all this talk.
I am wondering if the lighting issue has everything to do with the bezel? the housing is painted baby blue inside, then a very narrow margin for the light to escape between the housing and clock face. That light hits a dished backside of the bezel that is also bright blue & shaped in a way to reflect on to the face. Also the backside of the face looks like some sort of stainless. very reflective. Going to bet the aftermarket does not have that same detail, but just a guess.
I was surprised to find the spring in my clock was partially wound & not down on the contacts as I was expecting to find it. I don't see any broken springs, but thinking it might be just stuck from many decades of sitting. Thinking about a lightweight oil administered from a syringe, but not sure if that will cause more problems as I have no idea if these were originally oiled parts. they look very clean. Hmmmmm.
