It is a Hadley Roma LEATHER strap that is water resistant. I have seen rubber on a Hamilton Khaki and the Omega Planet Ocean over the past three weeks and that is where I got the idea to re-strap this new Invicta Orange Monster. . . my first "keeper" orange dial watch.
Up until now, I have always believed that a dive watch should either be on a rubber strap or SSTL bracelet, but after seeing how this watch looks with this beautiful leather strap, I am re-thinking my opinion.
From Yogi Berra: "Do you mean now?" -- When asked for the time.
I had that same watch and sold it because I thought the orange on the bezel was just too much. It looks great with that strap though. The guy I sold mine to put it on that same strap. You probably have seen pictures of it. If I had seen that strap I might have tried it although I have an aversion to straps.
