Timepiece oscillator assembly device

Abstract

To provide an oscillator assembly device improving the integration of a balance spring of an oscillator into a movement, without any mobile fastening support movable in rotation relative to a balance bridge or to a plate in a plane of the movement.SOLUTION: A device 200 for assembling an oscillator 100 including a balance spring 1 to an assembly 300 or movement 300 of a timepiece 400 comprises a first movement blank 5 for pivoting the oscillator 100, a second movement blank 6 for pivoting the oscillator 100, and a first element for positioning the first movement blank 5 relative to the second movement blank 6, the first positioning element being arranged and / or configured to position the balance spring 1 relative to the first movement blank 5 and / or relative to the second movement blank 6 in a plane P of the assembly 300 or movement 300.SELECTED DRAWING: Figure 1
