Bulova 1964 Jet Clipper

 I think this is a Jet Clipper variant.  Possibly the sibling of the N variant but with black dial, as mentioned in the attached 1966 add found on the site.   Stainless steel case that is just over 31mm in diamater not including the crown and lugs.  Black dial with stainless numbers at 12 and 6, wedge shaped indices at 3 and 9, and linear indices at the other positions.  Also a small, contrasting white outer track all around.  The seller I purchased this from billed it as having just been serviced.   In the 6 months or so since then I've given this one a bit of wrist time and it keeps excellent time.  Has become one of my favorites.

Thanks and still enjoying the site very much!
