Pedometer incorporated in a mechanical watch

A watch comprising a pedometer mechanism for estimating a physical activity level, comprising at least one moving or pivoting weight arranged to drive a ratchet, elastic or friction holding means for holding said ratchet in position between two movements of said moving or pivoting weight, wherein said ratchet drives a gear train displaying on a first display a value corresponding, to within a multiplicative factor, to the number of pivoting motions of said ratchet and/or to the value of the cumulative angular rotation of said ratchet, and wherein said pedometer mechanism comprises a limiting means only allowing the pivoting of said ratchet from a minimum threshold corresponding to a minimum travel of said weight if the weight is movable or to a minimum angular rotation value of said weight if the weight pivots, wherein said pedometer mechanism comprises a means for measuring the travel of movement of said moving or pivoting weight during each of its movements, and a means for cumulating the absolute values of the successive travels measured by said measuring means from an initial moment, wherein said watch comprises a control means for determining said initial moment and a final moment, and wherein said watch comprises display means comprising said first display and a means for the cumulative display of a magnitude homothetic to the cumulative value of said absolute successive travel values, and wherein said watch comprises a reset mechanism for removing the value displayed by said cumulative display means, wherein, each day, said initial moment is at zero hour, and said final moment is at midnight.
