I have already bought 3 watches and a movm. from him. The movement didn't work, but I found out 1 year after I bought it because I didn't use it. He replaced it without any problem. The last watch I bought from him was a VSF Starbucks Submariner, unfortunately it stopped after 40 minutes, I sent it back and they repaired it, unfortunately it was a 5 month process, but I am still satisfied and will buy from him again.
