The new generation of free-sprung movements has achieved significant improvements in timekeeping accuracy. Free-sprung designs regulate timing by adjusting weights on the balance wheel, offering better stability and less sensitivity to position changes than traditional regulated movements. Latest tests show new-generation free-sprung movements can stably keep daily error within +/-3 seconds, with amplitude maintained between 280-320 degrees. This technological progress brings high-end replica timekeeping performance closer to genuine levels.
