Bulova 1970 Accutron Calendar "X"
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.
