In about 18th and 19th century, pocket watch owners are plagued by a question: no matter how precisely they watches worked, they have to wind it up, and if, unfortunately, leaving it alone for a couple of days, then it will stop. Breguet had been thinking about the same question. It also found that the base clock has long energy reserve, and a higher precision. So he wondered if there was a force that could drive the watch to work?

So from 1793 to 1805, Breguet thought day and night and finally finished its great invention--PenduleSympathique. we could find more specifics from a latter Breguet writing to his son. In the letter, he said that he have invented a adjusting system with manual intervention. Its working principle is: it needs a base clock, or navigation clock and a supporter that could place this special clock. Every night before he went to sleep, he placed the clock in the supporter, and in the second day morning, they will find that the clock and watch are sync and the whole process did not require to open the case back, and Breguet expressed his hope in the letter that he can, with this invention, elevate its fame and strength.

Sooner, Breguet further perfecting it by adding a winding system to it. Maybe it is too complicated, there were only three clocks likes this during Mr.Breguet alive. After his death, another four were invented. But it has a horrible price that could stopped you mind of buying it. The first one was sold to Czar at 28,000 Francs and others were also sold to celebrities, but the base are skill kept in the museum.
