We have a deal with hundreds of Scrappers around the country that before they scrapped a pocket watch to give us a call! We couldn't say this one because it had almost $3,000 in scrap gold but we were able to save the movement. It's a curiosity as well. This fellow Nieberg may have been loosely associated with Tiffany according to the internet. He was quite a an accomplished horologist again according to the internet. Check out the serial number anomaly. A four digit serial number on the back perhaps his own and then a 5 digit serial number underneath The dial. Quite unusual. And not much is known about this fellow that I can find. Just that he made some chronometers and that he was an extremely competent watch repair. His first name was Frederick evidently. Anyone have any ideas on this?
