Patent ID: 8342739

Claim:
A method for realizing at least two horological movements operating at different oscillation frequencies, comprising the steps of: a) designing a common base for the movements, the common base comprising a wheelwork for connecting a barrel to an escapement in each movement, b) providing a first set comprising a regulating device having an oscillation frequency f 1 and an escapement for maintaining the oscillations of the regulating device, the escapement comprising an escape wheel with N 1 teeth, c) providing a second set comprising a regulating device having an oscillation frequency f 2 and an escapement for maintaining the oscillations of the regulating device, the escapement comprising an escape wheel with N 2 teeth, wherein the oscillation frequencies f 1 and f 2 are different, and the number of teeth N 1 and N 2 are different and the ratio between N 1 and f 1 is substantially equal to the ratio between N 2 and f 2 , d) manufacturing a first movement so that the first movement includes a first base according to step a) and the first set, and e) manufacturing a second movement so that the second movement includes a second base according to step a) and the second set.
