Riefler regulator

Riefler regulator ( # 24 )

	In the battle of exactly measuring the time, no doubt Riefler had an important role. With no rivals at all , the undisputed Graham escapement predominance was surpassed by Riefler's clock which has an innovative escapement where no pendulum parts under the suspension spring are touched ; hence the pendulum moves being not "disturbed." To guarantee uniformity in given energy to the pendulum, the clock features a remontoir wound by a magnet. ( electrical wires are clearly visible in the small picture on the right.) Time is adjusted by by adding or removing small weights from the round plate (also visible in the bottom of the same picture) fixed along the pendulum rod (adding weights, the clock gains, removing them, it loses). The precision of this clock was surpassed just by the "free pendulum clock" (where in spite of the name, the pendulum isn't anyway completely free). My regulator is based on a clock designed by J. Warby. the movement
