Breguet Duc D'Orléans Sympathique

This watch is the world's second most expensive Breguet timepiece. The Sympathique watch, designed by Breguet in 1795 and first shown to the public at the Exposition Nationale des Produits de l'Industrie in 1798, was a device that combined a clock and a watch. The pocket watch was held in its cradle by the clock, which mechanically adjusted and rewound it. Breguet coined the term sympathique to represent the idea of harmony and concord.

The extremely rare Sympathique clocks, of which this model is easily the best preserved, complete with working parts thoroughly repaired by the late George Daniels, contributed to the popularity and acclaim of French watchmaker Abraham-Louis Breguet.

It boasts the most complicated Sympathique mechanism of all known examples: the integrated cradle located on the clock's pediment is the only one known to wind, set time, and control its accompanying pocket watch. This exquisite clock was part of Seth Atwood's famed Time Museum collection, and its winding mechanism was restored by Dr. George Daniels, MBE, CBE, the most illustrious Horologist and watchmaker of the twentieth century.
