1977 Bulova Digital Quartz. Both case and movement marked N7. Movement also marked
"Bulova Unadjusted Japan No "0" jewels 3011.10" followed by "N7"
with two ink stamps.
Face marked "Bulova" with a drawing of a quartz crystal and "Japan MVT"
Movement model is an unknown by me, as these watches are way out of my collecting focus. Is one of the numbers on movement an identification of model?
It's a little threadbare, but I thought I would add this one just because the Db has none. Originality of band is an unknown.
