The career of Louis-Frédéric Perrelet was at its peak around 1820. He was full member of the closed circuit of famous Master Watchmakers and his reputation as scientist and inventor had spread to most of the European Royal Courts.
At the occasion of the Exhibition of French Industrial Products in 1827, Louis-Frédéric Perrelet presented an extraordinary Split-Second Chronograph. On September 20, 1827, he had his invention patented and this revolutionary timepiece won him a Gold Medal by the Academy of Science in 1830.
In an official write-up published at the occasion of the exhibition in 1939, this invention is again mentionned: «... His inventions feature functions lined-up in thoughtthrough displays and are generally of perfect quality. This outstanding workmanship relates to all the products created by this gifted artist who invented the split-second chronograph...»
The split-second chronograph created by the hands of Frédéric- Louis Perrelet is today exhibited at the Patek Philippe Museum in Geneva and is in perfect condition. It is without doubt one of the most outstanding developments in watchmaking of the 19th century.
