I have really grown to dislike polyurethane straps. They are stiff and plasticky; they feel uncomfortable to me. My only complaint about my Seiko dive watch is the polyurethane strap. I would like to ask the following questions:
1) What are the benefits of a polyurethane strap?
2) Does Seiko sell any natural rubber straps separately for their dive watches? If so, where can I buy one? (The ones on Amazon.com advertized as natural rubber seem to turn out being polyurethane, judging by some of the buyer's comments.)
3) Does anyone here prefer a polyurethane strap to a natural rubber one?
