By all accounts, Abraham-Louis Breguet (1747 –1823) was a world-renowned horologist, brilliant inventor and highly talented businessman. He was born in Neuchatel and went on to found a watchmaking company in Paris that built up an exclusive clientele throughout Europe and beyond. His customers included the Napoléon Bonaparte, Marie-Antoinette and Tsar Alexander I. Abraham-Louis Breguet is considered to be the «greatest watch maker of all time». His craft and life are the main focus of an exhibition that has already been shown in the Musée du Louvre and the Château de Prangins, and can now be seen in Zurich. With the help of numerous loans from Switzerland and abroad, the exhibition has brought together more than 170 watches, pendulum clocks, portraits, patents and other documents from the time of Abraham-Louis Breguet.
