摘要： The invention relates to a natural escapement (1) for a timepiece movement carrying out a succession of operating cycles each composed of a first and a second alternation of a balance (20) which comprises a balance wheel (22) on an axis (24) of which a balance plate (26) is fitted, this natural escapement (1) comprising a first escapement wheel (10) arranged to be driven by a second wheel (2), this first escapement wheel (10) in turn driving a second escapement wheel (16), the balance plate (26) carrying a balance pin (28) by which this balance plate (26) causes the pivoting of an anchor (34) at each of the first and second alternations, a first lever (48 a), pivoted about a pivot axis (50), being connected to a first arm (46 a) of the anchor (34) via at least one pivot joint (53), the anchor (34) comprising a second arm (46 b) extended by a second lever (48 b), these first and second levers (48 a, 48 b) being arranged to lock the first and second escapement wheels (10, 16) respectively temporarily during the second and first half-cycles of an operating cycle, the pivoting movement of the first and second levers (48 a, 48 b) being limited. The invention also relates to a clockwork movement comprising such a natural escapement (1).
