Natural escapement for a horological movement and horological movement comprising such an escapement

A natural escapement (1) for a horological movement performing a succession of operating cycles each composed of a first and a second alternation of a balance (12) which comprises a balance wheel (14) on an axis (16) of which is adjusted a balance plate (18), the natural escapement (1) comprising a first escapement wheel (8) arranged to be driven by a second mobile (2), the first escapement wheel (8) in turn driving a second escapement wheel (10) arranged in the same plane as the first escapement wheel (8), the first and second escapement wheels (8, 10) forming a kinematic chain after which is disposed an anchor (26) capable of pivoting around an anchor rod (28) located outside an angle (α) less than 180° and delimited by a first straight line and a second straight line, the first straight line passing through the axis (16) of the balance wheel (14) and through a pivot axis (6) of the first escapement wheel (8), and the second straight line passing through the axis (16) of the balance wheel (14) and through a pivot axis (11) of the second escapement wheel (10).
