I don't think I've seen this variant in the catalog, so I thought I would submit it. It looks like an Accutron Model "214" according to the POS ad. So it's confusing, but I think it's caliber 214 and model 214.
It may clarify some things, but it may also complicate the ID. When a case and movement are dated more than two years apart, its been our convention to note a movement swap at some point after Point of Sale (POS). We assume POS to be the latter of the various dates we have for watch "parts". We often, but not always, ID these as Non-Conforming. This can be true even when the swapped movement is the correct Movement Model which would have been in the watch at POS.
So with new information, we have a 1976 case housing a 1965 movement, which also happens to be the Movement Model that would have been used if the movement were produced/dated 1975/76.
Another question, since I don't know alot about accutrons. What was the last date of production for the 214 movement model verses say the 214H?
Dr Ranfft doesn't list an end date for 214's.
When I search watche records on site, our most recent 214 movement is from 1974.
Our movement dateabse lists an end date of 1977 for the 214, however there are no examples with which to validate this end date.
Lisa's site also lists this 1977 end date, however she doesn't have an example in her collection this late either. The most recent 214 in her collection is from 1971.
Could the ad be discribing a "hacking 214" movement (214H)? We do have 214H in our database as late as this 1977 example. I have no idea when the Hacking 214 was first produced, nor its end date.
Alternately, it could simply be that the screw on case back is not original to the watch....OR the case style was extensive used throughout the 60's and 70's.
I ID'd the cards based on the early hand configuration of the Astronaut model that is shown. Again it was just an estimate, but certainly places the cards (if all part of the same series) at the beging part of the 1960s.
ID wise, I'm good with Accutron Model 214.
I'm OK w/ Accutron Model 214
Still wondering what year they stopped producing 214 movements.
I don't know if the 214H movement continued to be sold after the 214 movement was discontinued? If the caseback is that of a model which housed a 214H movement in 1976, perhaps we would not find a 214 Movement in this model in 1976. It looks to me like both movements used the same style case backs. Bloody confusing with all these 214's :)
On the waterproof vs water resistant issue: I have restored many accutron's as well as Bulova diver watches of this era and find nearly the same rubber gaskets mounted between the movements and the case backs. The screw on cases give you extra protection. Waterproof as defined as immersible and or safe to be totally submerged in water and water resistant as defined as resistant to moisture.
