Abstract
A timepiece sub-assembly including a mobile timepiece element including first and second annular and opposite peripheral surfaces of revolution about a same pivot axis, and a device for guiding pivoting about a theoretical axis of a timepiece mechanism. The first surface is magnetically or electrically charged, and the device includes at least three first surfaces regularly arranged around the theoretical axis, oppositely magnetically or respectively electrically charged to the first surface to repulse it at a first interface. In a watch, the second surface is magnetically or electrically charged, and the device includes at least three second surfaces regularly arranged around the theoretical axis, oppositely magnetically or electrically charged to the second surface to repulse it at a second interface.
