Here is a vintage Timex display case which I have had since the '70s. It is all plastic with wood tone top & bottom. It has two circles on top for outside display. Clear inside has three shelves. Small metal clips to hold curved back in place. Backs have silvery side which faces outward. It does have a light in the top, but I have never plugged it in, so I don't know if it works. See photos for more info.
