This watchman Kieran Lynch really has an understanding of old watches. He met with me & explained to me about the watches that I had inherited. He fix my Grandpa's for me to use, and he bought the rest for a very healthy price. He told me that he buys old coins, jewelry & military relics as well, and I sold him some ww2 souvenirs from Grandpa's house. I would recommend calling Mr. Lynch with your watch questions.
