The device (3) for testing a timepiece shaft (1) having at least one first pivot (10, 10′) and an axis of rotation (A1), the device including a rest (2) having two supports (12, 12′) intended to accommodate the timepiece shaft (1), at least one of the two supports (12) being intended to accommodate the at least one first pivot (10), an element (4; 4′) for applying a mechanical force to the timepiece shaft, positioned such that this force is at least partially taken up by the support (12) at the at least one first pivot (10). The element (4; 4′) for applying a mechanical force is arranged such that the timepiece shaft (1) is driven in rotation by a relative movement of the element (4; 4′) for applying a mechanical force and the rest (2).
