The echappement naturel was an invention of Abraham Louis Breguet, the most eminent Swiss watchmaker. It was a form of escapement for watches which required no oil at the working surfaces and therefore was free from the deterioration in timekeeping that follows from the deterioration in the oil with time. It was described by George Daniels as 'Breguet's ultimate solution to the problem of a free escapement with natural lift'. Breguet produced only about thirty watches and clocks with this escapement between about 1802 and 1820 and then abandoned it. It was very expensive to make and only his very best workers were capable of its construction. A detailed description of the escapement and list of surviving watches containing it has been published in Antiquarian Horology in 2010.
