I'm not sure about the year of this watch. The case is dated1965, and the movement is dated 1967. When a watchmaker friend of mine died, I bought some of his parts from his widow. Included in the lot was 2 boxs of odds and ends and junk. In one box was this empty case, and in a small can was the movement with some missing parts, such as hands and hour wheel. The band was in the 2nd junk box along with some other bands and case parts from other watches. Recently I had an Accutron watchmaker put it together and service it. It could be that these parts came from more than one watch. Which doesn't matter to me personally, because it is such a good looking watch, and run s so very well.

An interesting note here. Look at the dial, its a gloss T-Swiss-T dial from a Swiss type 1 astro. The US astros have a matt black dial. Since I know the Swiss type 1s are about as rare as they get, I will enlighten everyone. They are not the same as a US one. They use a 339 case, a 339 crystal, (both are a little different from the US version) the GMT ring is different in that the Swiss version has a closed 4 (like this font) vs the open 4 that the US version uses. Its not the same case as a Swiss type 4 either. I think they can come in both a US 214HN and a Swiss 214HN movement depending on whether its a prefix (1-XXXXX) or a no prefix case. The 1- watches have the Swiss movement, the 5 digit no letter version uses a US movement.

I can't tell if the movement says its a 214HN or not. If its not an HN, its a replacement movement. That said, in my research for my Swiss 339 Astro, it appears the proper movements are never more than a year one way or the other of the case. That allows for a December 64 movement to go into an early 65 case, or a late 65 case to receive an early '66 movement. (Apply the case/year required for a specific watch in question.)
The HN parts for the GMT and the hack spring can be added to a straight 214 pilar plate/movement to make one work in an Astro. Based off this, I'd wager its a replacement movement, and without a doubt one if its just a straight 214 pilar plate.
