Method for creating a flexible, multistable element (5): a silicon component (S) is etched with a beam (P) connecting two ends (E1, E2) of a rigid mass (MU) having a cross-section more than ten times that of said beam (P), SiO.sub.2 is grown at 1100° C. for a duration adjusted to obtain, on said beam (P), a first ratio (RA) of more than 1 between the section of a first peripheral layer (CP1) of SiO.sub.2, and that of a first silicon core (A1), and, on said mass (MU), a second ratio (RB) between the section of a second peripheral layer (CP2) of SiO.sub.2 and that of a second silicon core (A2), which is less than a hundredth of said first ratio (RA); cooling to ambient temperature is performed, to deform said beam (P) by buckling when said mass (MU) cools and contracts more than said beam (P).

A natural escapement for a horological movement performing operating cycles each including 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 escapement (1) includes a first escapement wheel (8) driven by a second mobile (2), and driving a second escapement wheel (10) arranged in the same plane as the first escapement wheel (8). The escapement wheels form a kinematic chain after which is disposed an anchor (26) pivotable around an anchor rod (28) located outside an angle (α) less than 180° and delimited by two straight lines passing through axis (16) of balance wheel (14) and through a pivot axis of the first escapement wheel (8), and through the axis (16) of the balance wheel (14) and through a pivot axis of the second escapement wheel for the other.
