Finally getting around to leaving some well-deserved feedback.
I purchased a Seiko SNA129P1 from siLence79 near the end of August. He promptly shipped the watch, and provided about 15 photos of it being packaged and dropped off at the post office. The watch arrived without issue, and he even included a beautiful leather Nato that I wasn't expecting to receive.
Summary: No issues whatsoever, very polite, and highly recommended based on my transaction.
