It's a KIF 3 also known as Elastor.

Well, Rolex used KIF back in the day and the Omega Speedmaster I just finished up had the same KIF shock protector so the mid to higher end brands trusted them.

Are some systems better than others? I got the impression the performance between the differing options was pretty much the same. I'll admit some shock springs elicit more cussing during service than others though.
