This is my first accutron watch and it's a Bulova Astronaut !
Bulova astronaut m8 1968 type 4 with black bezel and white cream and Jb Champion bracelet ( bullet ).
Little scratch on glass but not a big deal still very clear. All tritium on hand ligtht in dark after 50 years ! I don't open the case yet because I need specific tool but I have open the battery slot, I put a energizer 387s md silver 1.55 v inside and after 30 years without work, I listened for the first time the bulova accutron system and his sound the "hummm". Amazing engineering of watch.
So I already love this watch !
