Louis Recordon (1756-1826) a watchmaker originally from Sainte Croix who settled first in Geneva and then in London, he was Breguet’s friend and agent in England and was responsible for selling approximately 75 of Breguet’s watches to the British, including some to the British Monarchy. He was also one of the first to develop the selfwinding watch and in 1780 was granted ‘Letters Patent’ by King George III, concerning an automatic winding mechanism.
