Abstract
A magnetic clock escapement, and a regulating device, the escapement including a first circular network formed by N1 magnetic lines and a second circular network formed by N2 magnetic lines, N2 being different from N1. The first and second networks are superimposed to define a combined pattern having a magnetic Moiré effect. The combined pattern is coupled magnetically to at least one magnet of a resonator to pace operation of a mechanical clock movement. The first magnetic structure is carried by an escapement wheel and can rotate relative to the second fixed magnetic structure with an angular frequency F1. The combined pattern rotates with a greater angular frequency F2 and equal to the angular frequency F1 multiplied by the number N1 and divided by the number ΔN equal to this number N1 minus the number N2, F2=F1·N1/ΔN.
