Marie Antoinette Pocket Watch
The Empress of France commissioned her favorite watchmaker, BREGUET, to make a watch capable of retaining all the most advanced horological knowledge of the time, regardless of time or price and no matter what it cost.
At his death ten years later, the Pocket watch was still being made, and it wasn't until more than thirty years after his death that the order was completed.
The Breguet No. 160 had a minute chime, perpetual calendar, charge control, thermometer, and many other functions. In 1983, it was stolen from the Jerusalem Museum, where it was kept, appearing a few years later when the Breguett firm was about to complete a copy. It is currently stored in Basel.
