Abstract: The invention relates to a mechanism for displaying an information for a timepiece, comprising a mobile (10) intended to be driven in rotation by the movement of the timepiece about a display axis (17), a satellite (20) pivoted on the mobile (10) about a satellite axis (27) parallel to the display axis (17) and remote from a non-zero distance d1 thereof, a display area (80), an indicator (50) secured to the satellite (20) and the position of which relative to the display area (80) provides the information, and a crown (30) centered on the display axis (17) and kinematically connected to the satellite (20). The mechanism is particular in that the indicator (50) is located at a distance d2 from the satellite axis (27), which is greater than or equal to the distance d1.

Abstract: The horological movement includes a mechanical resonator and an escapement including an escapement wheel, which has a plurality of teeth, and an anchor formed by a stick and two arms having respectively two mechanical pallets likely to come into contact, when the anchor is subject to an alternative movement, with any of the teeth according to the angular position of the escapement wheel. To avoid damage to the escapement during rocking of the anchor while the escapement wheel is positioned in an unfavourable angular position, the anchor is arranged, during the rocking of this anchor, to be able to bend being subjected to an elastic deformation. The anchor has an elastic capacity between each of the two mechanical pallets and a fork of the anchor, enabling it to absorb elastically, during the elastic deformation, a maximum mechanical energy that the mechanical resonator can have during the normal functioning of the horological movement.
