Guys, there are no problems with customs in the UK - UK customs are extremely rep-friendly. If you bring 'em in by the shipping crate you _might_ have a problem, but buying in twos and threes (or even more) is not an issue. I've brought over 40 watches into the UK in the last year - no problems.
Try any of the trusted dealers here or on the other rep watch boards and all will be well.
