Timepiece mechanism, timepiece movement and timepiece having such a mechanism

A monolithic timepiece mechanism made in a single plate of material, comprising a frame, a first elastic suspension and an inertial regulating member which is connected to the frame by said first elastic suspension so as to be able to oscillate, wherein the monolithic timepiece mechanism further includes a blocking mechanism having at least a blocking member connected to the frame by a second elastic suspension, said blocking member being controlled by the regulating member to be able to regularly and alternatively hold and release a movable energy distribution member so that said energy distribution member moves by steps, of a constant travel at each step, said blocking mechanism being further adapted to regularly transmit energy from the energy distribution member to the regulating member for maintaining oscillation of said regulating member,

• wherein the blocking member is connected to the regulating member by at least an elastic link so as to move in synchronism with said regulating member.
