Device () for displaying a magnitude on an oscillating weight () for a self-winding timepiece movement () comprising a means () of displaying said magnitude by comparison to a complementary display means (). Said display means () pivots coaxially to said oscillating weight (), and is subject to a general pivoting motion resulting from the combination of a first pivoting motion synchronous with that of said oscillating weight (), and a second pivoting motion resulting from said display means () being pivoted by said movement () relative to said complementary display means () integral with said oscillating weight (). Oscillating weight () including such a device (). Self-winding watch including an oscillating weight () comprising such a device (), and whose motions are transmitted to a mainspring of said watch.
