Abstract:
1. A timepiece wheel set, selected from among an oscillator mechanism or an escapement mechanism, wherein said wheel set comprises a first guide surface arranged to cooperate in a complementary manner, directly or indirectly with a second guide surface associated with a bridge, for pivotably mounting said wheel set relative to said bridge about a pivot axis, said first guide surface encircles said pivot axis, is unique and located on a median plane of said wheel set said median plane which is substantially orthogonal to said pivot axis, so as to keep said wheel set careened or in a cantilever arrangement relative to said bridge, and wherein said wheel set is guided at a distance from said pivot axis, wherein said wheel set includes, on a first side of said median plane a first means of applying torque relative to said pivot axis and, on a second side of said median plane a second means of applying torque relative to said pivot axis, so as to distribute the stresses exerted on said wheel set at said first torque applying means and said second torque applying means on both sides of said first guide surface.
