Abstract: The horological movement comprises a regulating device having an oscillation frequency (f) and an escapement for maintaining the oscillations of the regulating device. The escapement comprises an escape wheel having (N) teeth. The frequency (f) is at least equal to about 5 Hz, and the ratio between the number (N) of teeth and the frequency (f) is substantially equal to 5.

Abstract: The driving and transmitting element (10, 50) is in the form of a ring (20) having an outer face (32) from which a stud (40) extends radially. Application to a roller table (60, 70) of a lever escapement (80) for a timepiece (90) including such a driving and transmitting element (10, 50) for rotating the anchor (84) and for transmitting an impulse from the anchor (84) to the roller table (60, 70).

Abstract: A method for assembling a hard part made of a material the hardness of which is higher than 500 Vickers, a pivot organ, includes: having a pivot organ including a tubular portion and a bearing surface extending around the tubular portion; introducing the hard part freely on the pivot organ around the tubular portion, the hard part having at least one structure built in advance, defining an entry and pulling the hard part in contact with a malleable organ also set on the pivot organ around the tubular portion, so that it is positioned over the entry of the structure, this assembly being formed by the hard part and the malleable organ being brought to bear the support surface; deform irreversibly the malleable organ to create catches formed by the washer and housed inside the structure without any degree of freedom, the malleable organ made integral with the pivot organ.

Abstract: The present invention relates to a method for assembly of a hard part (12) made in a material the hardness of which is higher than 500 Vickers on a fixed support (10) consisting in being: equipped of a plate (18) in malleable material arranged to be tightly positioned on the support; equipped of a hard part (12) further including a geometrical shut-off element positioned so as to be able to cooperate with the plate; and equipped of a clamping element for sandwiching between the latter and the support, the plate and the hard part.
