I didn't know that.

However Dennison certainly made stainless variations on the Aquatite for special applications, such as the recasing of the Omega and Longines into the '56 6b/159. They also made solid gold watches to almost the same pattern as both the snapback and screwback Dennisons. I'm pretty sure I can dig up both versions from somewhere in the back of the safe.
