Abstract
The mechanism preventing rate variations caused by the effect of gravity on a regulating member () of a timepiece movement comprises a regulating member comprising a balance-spring () and an escapement wheel () which are mounted on a platform (). This platform () comprises an unbalance and is mounted so as to freely rotate about at least one first axis (A-A) with respect to a plate () of the movement so that the platform () rotates about said first axis (A-A) under the effect of the Earth's gravity. The mechanism comprises a going train comprising a kinematic drive chain (M) arranged to connect the escapement wheel () to a barrel system () of the timepiece as well as a kinematic correcting chain (C) which compensates for the displacements and speed of the platform () with respect to the plate (). This mechanism is characterized in that it further comprises a regulator device comprising a regulator member () connected to the platform () and driven by the relative movements between the platform () and the plate () of the timepiece movement.
