Abstract
Abstract 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 oscillatorescapement 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
A movement for a piece of horology, comprising two subassemblies, the first subassembly comprising a base movement supporting time-setting means, winding means, motor means, transmission means and a housing for regulating means, the second subassembly comprising said regulating means supporting escapement-oscillator means, said piece of horology having a second wheel and an escapement wheel having a pinion, and means linking said two assemblies between said second wheel and said pinion, said regulating means comprising a median frame having reference means for securement to said first subassembly and supporting at least one bearing of said escapement wheel, a lower bridge carrying another bearing of said escapement wheel on a frame of said piece of horology and comprising also a bearing of said regulating means, another bearing of said regulating means being carried by an upper opposed bridge mounted over said frame.
Claim 2
Dependent Claim
140 words
A movement for a piece of horology, comprising two subassemblies, the first subassembly comprising a base movement supporting time-setting means, winding means, motor means, transmission means and a housing for regulating means, the second subassembly comprising said regulating means supporting escapement-oscillator means, said piece of horology having a second wheel and an escapement wheel having a pinion, and means linking said two assemblies between said second wheel and said pinion, said regulating means comprising a median frame having reference means for securement to said first subassembly and supporting at least one bearing of said escapement wheel, a lower bridge carrying another bearing of said escapement wheel on a frame of said piece of horology and comprising also a bearing of said regulating means, another bearing of said regulating means being carried by an upper opposed bridge mounted over said frame.
Claim 3
Dependent Claim
49 words
A movement as claimed in claim 1, said reference means comprising a sleeve around which said regulating means is freely adjustable, said reference means also comprising at least one wall of said housing against which a portion of said regulating means comes to rest when secured to said movement.
Claim 4
Dependent Claim
39 words
A movement as claimed in claim 1, said regulating means being secured to the movement through resilient means permitting momentary displacement of said regulating means under shock while ensuring a continuous linking of said second wheel to said pinion.
Claim 5
Dependent Claim
15 words
A movement as claimed in claim 1, said median frame having a sliding stud-carrying member.
Claim 6
Dependent Claim
43 words
A movement as claimed in claim 1, in which said housing has a cut-out entry in which said lower bridge is housed with said escapement means, said housing having a flat reference surface on which positioning means for said regulating means are disposed.
Claim 7
Dependent Claim
44 words
A movement as claimed in claim 5, in which said entry and said surface are so disposed that said regulating means can be initially positioned and then slid on said surface to a final position for linking between said second wheel and said pinion.
Claim 8
Dependent Claim
22 words
A movement as claimed in claim 1, in which said median frame guidedly carries said lower bridge by means of three columns.
Claim 9
Dependent Claim
17 words
A movement as claimed in claim 7, in which said regulating means contacts one of said columns.
