Will, I think these are worth keeping if they are in Bulova cases. I'm not so sure they are. I suspect, or have a hunch, that they might be Accutron movements retrofitted into someone else's case.
As to what to categorize them as, I think it would be best to keep them as Pocket Watches.
If you pop the back lid off you will see the date code and movement model number on the inside of the back lid not to mention the movement it's self, i have three just like it, i have a N6 with a 218 movement, N7 with a 219 movement, and a N8 with a 242 quartz movement, All three of them have "Bulova" stamped on the inside back lid, both the 218 and the 219 are tuning fork movements and they both have the Accutron tuning fork symbol on the dial but the 242 quartz says "Quartz" in place of the tuning fork logo so this one is a 1977 or lower, how much lower depends on when Bulova started to use the 218 movements as this pocket watch never used the 214 movement, in fact i don't believe that Bulova ever made a pocket watch of any kind that used the 214 movement........
In 1974 Bulova made a solid sterling silver pocket watch with a 2181 movement, The dial had a analog calendar date right above the 6 o'clock mark unlike the type shown here where it has a calendar date, day at the 3 o'clock mark, i can't say about other years the sterling silver pocket watches might have been made.......

As far as I know, with the exception of a custom built one in 1960, which is, as far as I know, lost, pocket or pendant Accutrons began in 1965. I do not know of any hunter case Accutrons prior to 1975. I have 2 from 1966, and a hunter case from 1975 (per date codes).
