This is the finest of the Swiss made mantle clocks. It's in excellent condition and keeps perfect time. These clocks are considered to be the "Rolex" of Swiss clocks. They cost many thousands of dollars new. Made byJaeger‑LeCoultre, they are powered by changes in atmospheric pressure and never need winding or any other power source. This is a rare opportunity to own a beautiful piece of art that's also a well-known part of time-keeping history. Included is the original manual, original shipping boxes, and a manual for detailed information about how they work. They're quite delicate if mis-handled and I will not ship it. The $495 price is rock-bottom for one of these clocks in excellent condition. Do some online research, including recent completed sales on Ebay. Serial Number 537353.
