Value/ year made
The year made cannot be determined from the SN. Since the '50s Bulova used a 2 character date code, usually below the SN. The letter is the decade, the number is the year. For example, M4 is 1964, N6 is 1976, O5 is 1985, etc. As to value, if it is from 1960 through 1976 (M0 thru N6) it is a "true" Accutron, with a tuning fork movement, is collecrible and valuable, and the actual value depends on which specific movement and which case. Some 1977 (N7) Accutrons are akso collectible rtuning fork watches, but some 1977s are Bulova's first quartz watches, and of no value. Bulova eventually went mostly automatic (self-winding mechanical movement) with their Accutron line. Those are well-made, mid to upper-mid level watches, and of no particular value beyond that of most any good used automatic. Note, however, that there have been numerous versions of the automatic Accutrons, some fancier and nmore expensive than others, and, s ith any good watch, original cost will have an effect on value as a used watch. For example, that retailed at, say, $500 new in 2009 will be worth more today than one that was $250 new in 2009 (assuming comparable condition). There are also now some Accutron IIs, which mimic, in looks and the sweep second hand, the original tuning fork Accutrons. However, while they are well-made watches, they are just another nice quartz watch.
