If you haven't held one it is worth finding one just to play with the strap. Very flexible like a snake and soo soft, then the little fins on the back just allow a little air under the strap and also allow a little movement as your wrist size changes during the day.
How it will look in a couple of years nobody knows yet, but I will also be interested to find out. I asked the head of Rolex UK tonight what it actually is as it isn't rubber or silicon but he didn't know what it actually was made of, he messaged his technical friend at Rolex but he wouldn't say either..!!
