A masterpiece from the workshop of the celebrated master watchmaker Abraham-Louis Breguet (1747-1823), ‘Watchmaker of the Kings, King of Watchmakers’. This piece is a testimony of French Marine chronometry at its best, one of Breguet’s rare eight day Marine chronometers with power reserve. As a member of the Board of Longitude in Paris since 1814, Abraham-Louis Breguet contributed significantly to the development of Marine chronometers.
