Yes, I can believe that. It's called roll forming, where the metal is rolled through a progressive series of dies with each one rolling the edge over a bit more then the last
Here is the magical die. I wonder if Submariner got a similar die made. The fellow who made mine said he did a similar die about two years ago. I too prefer to own my own tooling.
