I don't have the watch on hand today, wearing a 423. I shall click pics when I get home. Although the colour is very close (maybe just a tinge darker) to what you see in the pictures and quite a bit lighter than yours.
However I am quite sure this is how it is supposed to look - I saw a Pam 690 a few weeks back and it had this strap - which is when I fell in love with it. The colour was almost the same as mine.
In any case, the strap comes directly from the Panerai Boutique, with whom I have been dealing for years. So if you find anything fishy, I'm protected.
