The co-axial escapement is a type of watch mechanism invented by George Daniels in 1974. It improves the accuracy and longevity of mechanical watches by reducing friction between moving parts. This design allows for a more efficient transfer of energy, which helps maintain consistent timekeeping. In a traditional escapement, the pallet fork and escape wheel interact in a way that can create wear over time. The co-axial escapement uses a unique arrangement of gears that align the escape wheel and pallet fork, minimizing this wear and enhancing the overall performance of the watch.
