Abstract
A mechanical horological movement () including at least one barrel system () for driving a set of wheels and power reserve detector. The detector () includes a control wheel () disposed opposite the cage of the barrel system () and is rotated by a complementary wheel () at the differential output to determine a power reserve level. An aperture () has a first end () to define a complete charge of the barrel system and a second end () to define a complete discharge. A lever () is rotatably mounted about a lever axis parallel to the axis of rotation of the control wheel. A contact element () disposed in the aperture contacts the second end during a zero power reserve indication. A portion of the lever contacts a component of the movement to stop its operation when power reserve indication is at zero.
