Welcome to my Top Swiss Wristwatches Boutique! Perrelet SA is a Swiss luxury watchmaker based in Biel/Bienne, Switzerland. Founded in 1777 by Abraham-Louis Perrelet, the inventor of the automatic watch. After his death in 1826 his famous grandson Louis-Frédéric Perrelet followed his footsteps and took the prestige Perrelet name further. Since more than 250 years the name of Perrelet is synonyme of highest quality and great style. Abraham-Louis Perrelet (1728 – 1826) was a Swiss horologist. He was born in Le Locle, then in the Principality of Neuchâtel. His father, Daniel was a carpenter and a farmer and as soon as the young man was in a position to do some favours, he helped his parents on the farm. At the age of twenty years he gave up his modest work to learn watchmaking. After an apprenticeship of fifteen days at one named Prince, in Le Locle, who worked little and very badly, and where he learnt absolutely nothing, he started to work independently and so became his own master. About the beginning of 1777, Perrelet invented a self-winding mechanism for automatic watches. It worked on the same principle as a modern wristwatch, and was designed to wind as the owner walked, using an oscillating weight inside the large watch that moved up and down. The Geneva Society of Arts reported in 1777 that fifteen minutes walking was necessary to wind the watch sufficiently for eight days, and the following year reported that it was selling well. Perrelet is thus widely acknowledged as the inventor of the "automatic" watch. However, his watch probably used a weight pivoting at the side of the movement. The first drawing and accurate description of an automatic watch with a central rotor was created in 1778 by the watchmaker Hubert Sarton and that design is attributed to him. Following the work of Perrelet, other watchmakers also created automatic watches from about 1777 on. Perrelet sold some of his watches to a contemporary watchmaking luminary, Abraham-Louis Breguet around 1780, who improved upon the mechanism in his own version of the design, calling his watches "perpetuelles". They did not work reliably and Breguet stopped producing them around 1810. Louis-Frédéric Perrelet (1781–1852), a grandson of Abraham-Louis Perrelet, was trained by his grandfather and went into business in Paris. Louis-Frédéric invented marine watches with measuring instruments and a split-second precision chronograph. He won one of three Lalande awards for 1830. Connoisseurs really appreciate the little details that Perrelet puts into its watches.
