I have his Yachtmaster, from way back when he was Watchmaker8 (seriously). A couple of flaws, including skinny minute hand and ticks that stop short of the edge of the face. However, this is one of the highest quality reps I have seen, in terms of fit and finish. After 2-3 years it looks great, gains about 10 seconds per WEEK, and is guaranteed water resistant to 100 meters.
My MBW white SD cost as much and was delivered with the O-ring sticking out from under the back (but concealed by the end link so I didn't notice until after it got wet).
I wouldn't buy again at Watchmaker9 prices (except maybe the modern Seadweller, look at that thick crystal!) but he shipped very fast from US, easy payment options - I have nothing bad to say about George (but he is not THAT George).
