I purchased this watch in Poland auction web site.
Hints were out of watch and the mechanism was unclean.
Watchmaker repaired the watch and now it is in very good condition.
FYI: this model sometimes had no other markings on the dial other than "Bulova Accutron" or, in addition, it could be marked "Traveler" at the bottom of the dial or "Astronaut Mark II" at the bottom of the dial. Many call these models "GMT" but I don't know that Bulova actually referred to them as such. Some models had the GMT hour window as shown on this watch while others had the additional GMT hour hand. It is correct to refer to all variations as "Accutron Astronaut Mark II". I have one with the unmarked dial as I described. I also have an ad showing the watch I have but calling it an "Accutron Astronaut Mark II".
