Abstract:
1. Horological movement comprising an energy accumulator ( 4 ), wheel units ( 1 , 2 , 3 ) on which are arranged time indicating members ( 1 ′, 2 ′, 3 ′), kinematic connection means creating multiplication and demultiplication ratios between the different wheel units ( 1 , 2 , 3 ) and a regulating member ( 5 , 6 ), the energy accumulator ( 4 ), the wheel units ( 1 , 2 , 3 ) and the regulating member ( 5 , 6 ) being arranged coaxially, characterized in that the horological movement also comprises a differential ( 8 ) arranged coaxially with the energy accumulator to provide the kinematic connection between the energy accumulator ( 4 ) and one of the wheel units ( 1 , 2 , 3 ) through a main arbor ( 7 ), and a main pipe ( 15 ) which is fitted coaxially around the main arbor ( 7 ), said pipe ( 15 ) being designed to support both the other wheel unit or units ( 1 , 2 , 3 ) and said kinematic connection means.
