Hi Lisa - There really wasn't a formal transition from Mechanical (hand wound) to Automatic (wound by wrist/arm movement) to battery powered Accutron (tuning fork) to Quartz powered battery watches movements in the Bulova timeline. Over a period of roughly 25 years (1950 to 1975) the three latter types were produced en masse. Three of the four continue to be made today, the exception being the Accutron Tuning Fork movement although to be clear all four types were 'jeweled' watches. In the mid seventies Bulova switched their battery operated watch movement from being driven by a tuning fork to being driven by quartz. On another note, Accutron has recently introduced a new concept in watch movement called "electrostatic" that is fascinating in it's design.
Our primary goal at myBulova is to help people discover the history of their vintage Bulova watches. Using ephemera, advertisements and some Bulova supplied catalogs we try to pinpoint all the information we can, including sell price and model numbers and names. We are not sure what exactly your watch is, as it seems to have components of a couple different types of Bulova watches specifically a case that was used in mechanical movement watches and a dial that seems to come from an Accutron tuning fork watch. Based on your comments the movement seems to be mechanical, not tuning fork. Because of that we most likely will not be able to supply any further information as it doesn't seem to be an original factory produced configuration. Generally we refer to watches we cannot ID to model as "Unknown" model.
If you have further questions I would be happy to try answer them.
