In some situations yes, but not in relation to replica's, common sense should prevail here. If you take a rep into an AD to buy a strap, it will go down like a lead balloon. My advice would be to buy it over the internet, if you want to see it on the watch first, buy a very cheap strap that is of similar colour, or have a look at some pictures on here, I'm sure the combination you are after would have been covered somewhere, hope this is of help.
