Chopard is a French jeweler that started out as a watch maker in the 1860s...They are known today more for their jewelry and their"Happy diamond " line of watches and jerwelry...About 10 years ago they had alot of write ups in trade magizines because they once again wanted to be taken more seriously in the watch trade by once again making their own speciality movements for their watches.I would go to
www.chopard.com and find e-mail them with a pic and numbers from your watch or go to a retail jeweler that carrys chopard and ask them to help you with an appraisal of the piece.The retails are high on Chopard jewelry and watches ,but the resale on their watches are disapointing.
