Zusammenfassung:	The invention concerns a watch movement in which the oscillator escapement system is mounted on a separate assembly which is insertable into the watch movement which has reference and fixing means for said separate assembly. The separate oscillator-escapement assembly comprises a median frame, a lower bridge and an upper bridge serving as supports for the bearing of the escapement system and of the oscillator. Said median frame comprises a planar surface adapted to cooperate with said reference means of the movement.
