It all depends on how use the strap. When I was young, I had Casio digital watch, the strap that came with watch never broke on me. It usually came undone at pins. Yes, they do recommend Rubber or Nylon type of strap for hiking.

This one caught my eye. But I think Silicone would be sticking to my skin. I don't know if I would like that?
The metal bracket starp, I think can be undone (opens) frequently. Ever if you shorten the strap. Personally I don't like the feel of metal.
Leather straps are OK but they wear out quickly. Smell of leather and sweat.
