The escapement was in development for eight years. It has a circular frame with a pallet fork in its center. This pallet fork is held in place by two blade springs, each less than a micron thick: that’s one tenth the width of a human hair. The blades are perpendicular to one another and snap back and forth as the escapement oscillates; UN likens the metal’s movement to that of a snapping hair clip. There is no pallet staff needed, and the pallet arms pivot back and forth due to the tensile energy of the blade springs. The redesigned pallet fork requires less energy from the balance wheel in order to reach its tipping point, which means that the oscillations of the balance can maintain a constant rate. Every part of the escapement is made of silicon, which makes it both lightweight and more durable.
