Sesame Chain is also called ‘Pagoda Wheel’. It first appeared in complicated function pocket watches and marine astronomical clocks. One end of the sesame chain is connected to the main barrel, and the other end is connected to the ‘Pagoda Wheel’ (named after the cone-shaped pagoda spiralling upward). When the mainspring is released, the sesame chain will gradually turn away from the pagoda wheel and surround the mainspring mainspring box. When the mainspring is fully wound, its power is maximum, and the sesame chain will move to the circle with a thinner (smaller torque) at the top of the pagoda wheel. When the mainspring’s power is almost released, its power will be minimal, and the sesame chain will circle The lower end of the pagoda wheel is thicker (larger torque) on the circumference. In this case, no matter what the power of the mainspring is, the torque transmitted to the escapement wheel remains the same, which can greatly improve the accuracy of the watch.
