The mechanical timepiece regulator of the invention comprises a flexure bearing oscillator and a double detent escapement, the oscillator comprising a balance wheel () connected to an elastic suspension () arranged to guide and apply a restoring force to the balance wheel () in a plane of oscillation. The escapement comprises an escape wheel () and an anchor () integrated into the balance wheel () and having two arms () arranged to receive alternately the impulses of the escape wheel (). The escapement furthermore comprises two detents () alternately locking the escape wheel () between two impulses and interacting with the arms () of the anchor to release the escape wheel () before each impulse, without direct interaction between the anchor and the escape wheel.

Mechanical timepiece regulator

Mechanical oscillator for a horological movement, comprising: a central fixed part being configured to be fixed to a frame of the horological movement; an inertial rim coaxial with a pivoting axis of the mechanical oscillator; at least two rigid links extending radially between the central fixed part and the inertial rim and supporting the inertial rim; and at least two flexible links extending radially from the central fixed part; each flexible link comprising a first flexible element and a second flexible element substantially coplanar to the first element, the first flexible element and the second flexible element being rigidly connected at their distal extremity; the proximal extremity of the first flexible element being fixed to the fixed part and the proximal extremity of the second flexible element being fixed to one of said at least two rigid links, such that the inertial rim can oscillate around the pivoting axis.
