al_Kaholik, if you're after a good Tropic strap I've just bought one off ebay from a guy called Dan who has a You Tube channel called Watch Me With Watches. It is FKM rubber so its quite flexible and doesnt attract lint, it fits my wrist quite tightly but really isn't uncomfortable as you might think. I don't have the largest wrists, 6.5 inch but it sits really well.
I've just seen he has a Waffle Strap in FKM in stock so will be buying one of those soon.
Been looking at that Pearldiver a bit recently, but I've come to the conclusion that I'd still prefer the NavyGraff like yours, ju
