Abstract
A regulator comprising two limiting members in the form of a blanked and bent tongue of a lug and of a detachable part serving as a pin or key, respectively. Part of the side surface of the tongue bent at a 90.degree. angle projects to form a banking. The detachable limiting member, which can be rotatingly adjusted about its axis, is fitted in the entrance opening of a cut-out portion and includes a projecting edge constituting the other banking. The two bankings are visible from above between the side surface of the bent tongue and the entrance opening of the cut-out portion so that the regulation of the beat of the balance-spring can be checked under a microscope.
