摘要： A regulatorless oscillating system for a watch includes a spiral balance spring having an inner fastening point attached to a collet which can be connected to a balance staff, an outer fastening point connected to a balance spring stud, and an end region adjacent to the stud. The end region is held so that it can be adjustably positioned in a plane which is perpendicular to the balance staff, thereby decentralizing the balance spring in order to compensate for isochronism errors.
