What Abraham-Louis Breguet set out to achieve was at once simple and highly ambitious : a watch which would wind itself, without the aid of a key or any other external agency. In his customary fashion, Breguet never laid claim to either the idea or the term “perpétuelle”, taking credit merely – if that is the appropriate word – for the invention of a system that was reliable and effective : an oscillating weight “à secousses” which responded to the wearer’s movements and ordinary walking. The oscillating weight, sprung so that it returned to its original position after each movement, pushed up two going-barrels, stopping when the springs were fully depressed.
