One of a few American (Czech) watch I own . This is a nice vintage Automatic Bulova from 70's, it has a French calendar :) with a Bulova 17 jewels caliber 11 ANACB (you can see the beautiful B logo engraved in the rotor, although there is not the Accutron logo :)).
Info about the specs of the Bulova Cal. 11 ANACB; here.
If you want to read more about the history of Bulova; here.
