Thanks for the reply guys. I've had a much closer look at the strap and have noticed that it has the number 24 on the inside of the rubber retaining strap that has caoutchouc on it. You wouldn't see it unless you're really looking for it. I'd guess that it's the kind of detail that a 'rep' maker would overlook? The finish of the strap is immaculate so I'm happy to accept that it's genuine - and whilst I might have paid a little over the odds, at least I've not been conned! Just gotta wait for my Ultimate version to arrive now. I'll will be posting comparison pics between Ulimate and standard version for anyone that's interested.
