Co-axial escapement
From Wikipedia, the free encyclopedia
Co-axial escapement is a type of watch escapement mechanism invented by English watchmaker George Daniels. Considered by many to be one of the most significant horological advancements since the invention of the lever escapement, the co-axial escapement functions with virtually no lubrication thereby eliminating one of the shortcomings of the traditional lever escapement. By utilizing radial friction instead of sliding friction at the impulse surfaces the co-axial escapement significantly reduces friction, theoretically resulting in longer service intervals and greater accuracy over time. In 1999 Omega introduced the first mass-produced watch incorporating the technology.
