I should have followed this up.
I received my watch in 11 days. I paid an extra £20 and got the Tudor Box so all in all £325 including postage. The watch is everything I could have hoped for, I wear it daily. I would say it's as close as you can get to the real deal, I was in the shop 2 days before receiving it and had the real thing in my hands. I asked for watcterproofing and this was done at no extra cost and he sent a video of it happening. At all times I was able to ask for updates and received lots of pictures and messages to keep me in the loop.
