I was looking for a Ulysse Nardin Maxi Marine Chronometer 263-66 and found that Camdamonium was in possession of couple that he was selling. I reached out to him and he was very cordial and helpful. The transaction took place on a Friday evening and I received the watch in perfect condition the following Wednesday. I would purchase again from him without any hesitation. He was a joy to work with and stands behind his products.
