Birth of Abraham-Louis Perrelet in the Neuchâtel mountains of Switzerland. This man was a master of his art and his talents and genius have become a reference through the ages. Interested in the watchmaking trades, he devoted himself from his adolescence to the construction of a certain number of precision instruments.


From the 1770s, he concentrated on devising a system, which after an initial impulse, would continue to function indefinitely. In 1777, he completed his revolutionary invention: the automatic self-winding movement. To this day, no one has found a better way of animating mechanical calibres.


That year, he finalised the first Pedometer and so became the first person to make watches with cylinder, duplex, escapements, date watches and equation watches. He fine-tuned the gear train even further, improving the pinions, wheels, escapement and winding mechanism.


Louis-Frédéric Perrelet was born in 1781, inheriting his grandfather’s watchmaking genius. As he displayed a liking for mechanics and mathematics, he was educated by his grandfather, before setting up in Paris to study in the Breguet workshops. Thanks to his talents, he quickly showed himself to be an independent watchmaker.


His growing interest in astronomy, physics and mathematics encouraged him to create the so-called “ intel-ligent ” watches. An astronomical clock designed in 1815 and presented at the Universal Exhibition in Paris in 1823, earned him the royal appointment as watch-maker-engineer to three kings of France.


For the occasion of the Exhibition of French Industrial Products, he presented an exceptional fiy-back counter for physics and astronomy. This instrument, for which a patent was officially granted to him in March 1828, won him the Academy of Sciences medal in 1830.


In honorary recognition of his Europe-wide reputation, Louis-Frédéric Perrelet, highly regarded for his talent and perseverance, was elevated to the level of Knight of the Legion of Honour in 1834, in addition to the many gold medals he had received.
