Abstract (en)
[origin: EP2450755A1] The wheel (1) has a toothed release wheel (4) including a movable gear (5) that includes a release tooth (6) and a locking tooth (8). The release tooth has a drive unit (11) arranged to cooperate with complementary drive unit (12) comprised in the locking tooth to drive the locking tooth in a radial direction (S2) when the release tooth is driven in the direction opposite to another radial direction (S1). The drive unit is arranged to move at a distance from the complementary drive unit, without driving the locking tooth when the release tooth is driven in the latter radial direction. The escape mechanism is is made of micro-machinable material, or silicon, or quartz or a silicon or quartz compound, or an alloy derived from microelectromechanical system (MEMS) technology, or an alloy obtained via the Deep reactive-ion etching (DRIE) or lithography, electroplating, and molding methods, or made of an partially amorphous material. An independent claim is also included for a timepiece movement comprising an escape mechanism.
