Reserve de Marche is a term used to describe a type of mechanical watch movement. It is a mechanism that stores energy in a separate power reserve, allowing for an extended period of time without needing to be manually wound. This feature is useful for watches that are not worn frequently, as the watch will still keep accurate time when not in use. Reserve de Marche is a feature that is generally found on higher-end watches, and it is a feature that is often admired by watch collectors.
