It's strange how there are so many "horror stories" being banded about !! I have bought a number of watches from Paul and I've only had one that needed major surgery ! Paul is always prompt with his emails and his service is generally good. Where he lets himself down is his after sales service. Therefore, if you get a good watch from him - no problems, if it dies, be prepared for aggro !
Also, like many of the members of this board, I have a number of watches with the Asian 7750 (I don't know whether they are the old or new versions !). So far, I have found them to be extremely reliable and keep very good time. Funnily enough, I've had more trouble with Swiss ETA movements !!
