So many questions about this watch. What is it? Has the N0 stamp on the back indicating 1970, but I've been through the models and adverts from '68 to '72 to no avail. Has the top lugs and textured finish of a 1970 Accutron Calendar, and the bottom looks like an Oceanographer or Jet Star. And what about this band? Pretty sure it doesn't belong to this watch, but any ideas what it is supposed to go with? 

Case measures 34mm across the top and tapers down to 20mm at the bottom. 42mm from top of lug to bottom point of the case. 

Final question is what would be the proper battery to instal?

I really appreciate all the help and thanks to everyone out there.

Check the new Accutron ads forum thread.... and maybe check both the 1960's and 1970's forum threads too.  Sometimes, Accutron ads get placed in the decades threads too.
Close to this 1969 ad.
  

Close to the "X"

Great looking watch Dane, very distinctive. I think the shape of the case is intended to invoke the Accutron tuning fork ( turned upside down). I like the rays incised into the bezel. I think it looks more like the Accutron Calendar "X" model than the "BG." That ad clearly shows the seconds railroad track that is not visible in the advert for the BG. The only thing missing are the luminous dots shown in the advert.

Someone knows which battery, Seems like there is a 1.35v battery available now with a retaining holder on it, maybe try google?

I agree it is closer to the "X", but the seconds railroad track is a bit different. From what I can tell there were never any luminous dots, but I checked the hands and they still glow. Thanks for finding the advert Geoff, do you what year it came from?

I too think its closer to the "X" variant, sans the luminous dots...

Closer match to the "X"; the "BG" uses numerals on the dial but the cases appear the same; does the subject watch dial have no luminous dots or markers at all, or signs that it once did? If so, why would it have luminous hands; that would seem uncommon to not have both.

Subject's dial has been refinished, but still an "X".
