You've really got to find a way to try one on. I, like many others, find the 1950 to (unfortunately) not fit the wrist well. It just doesn't sit right on me. I really wanted a 312 at first but, after trying it on, ended up with a Bettarini style that's suits me much better. Of course, if it works for you, and it does for many, it's a great looking case.
Good luck with the hunt!
