Thanks again all. I've tried Govberg, Michael Ashton, Tourneau, Betteridge. I did see a piece on Chrono24 but I wasn't sure. I'll take another look. Watchbox also has 3119 but haven't seen 5119. I really appreciate all the help. I will continue searching these sites. On chrono24, there is a NYC dealer located in the jewelry district, Hard to trust without a reference.
