In 1999, with the successful own development of Calibre 2500,Omega made history by introducing the first mass-produced watch incorporating the co-axial escapement — invented by English watchmaker George Daniels. Considered by many to be one of the more significant horological advances 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. Through using 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.
On January 24, 2007 Omega unveiled its new Calibres 8500and 8501, two co-axial (25,200 bph) movements created exclusively from inception by Omega.
