Thanks Ron. And, it's interesting that the purists in the military watch collecting field seem to want the older one-piece case design. Maybe it's because it's no longer in production and thus perhaps considered less available. But, seems to me if you're going to the expense and trouble of putting a nice Swiss-made 17 jewel movement in a watch there would be a simpler way of servicing it than putting it inside a one-piece case. Yet, there's no doubt that the one-piece case lessens the likelihood that moisture will penetrate through a separate back.
