This has been niggling at me so I went away and looked up all the Carl Sagan photos I could find- he wears this watch for a period of at least ten years and I am now of the opinion that it is not a Seiko H239 but a Seiko H127 model- the big square digital display is common on H127s but only appeared on a couple of H239s which normally have a large trapezoidal digital display under the analog section.
