Paul, there is a dealer "UK Watches" on RG selling this watch...and the best part is that he is asking ppl to make him an offer on the watch. You might pick up a bargain here.
I have one from Angus...which he informed me was the same one as Josh/Andrew sell...and it fits really well. It was a b*t*h getting on but it does fit flush with the case. He also sells it for $40.
They are shipped from the states (New York I believe).
I ordered 2 last week, shipped to the UK and had no customs issues. They were also unbelievably quick in delivering the straps. I ordered on Monday, was sent an email with pics of the actual straps on Thursday, and they dropped through my door on Saturday.
For the price of these straps, you can't go wrong.
