Hello Everyone, I recently purchased a used Tudor North Flag from Matt (aka Mdgrwl) and I was very satisfied with the service he provided. Matt not only answered my questions in an expedited and courteous manner, he also made sure to follow-up with me after I received the watch to ensure I was happy with the purchase. Out of several other sellers I have dealt with (on other forums), I can confidently say that Matt is so far the best one!
