Watchmaker K2 showed me this Aqualand Citizen diver recently. It comes with the original ND limits rubber strap. After replacing the batteries, he proceeded to try it on. Just then, the strap broke but amazingly, the watch did not fall off his wrist.
On examining the broken strap, we found out that there is this mesh (pic below) embedded in the rubber that held the broken strap together.
So now I know how good the ND Limits rubber strap is.
