Omega De Ville and the Co-Axial escapementThe Omega Coaxial watches are officially certified C.O.S.C. chronometers. The coaxial escapement, one of the major horological inventions of the 20th century, eliminates practically all friction between the escape wheel and the pallets, which has long been a source of problems in regards to the lubrication of mechanical watches. The result is a movement with longer lifetime, service intervals and with increased accuracy. Omega, after 150 years of experience and technological achievements made wachmaking history when it met the challenge of realizing George Daniels' long-held dream. Unwilling to admit defeat, both George Daniels and the brand believed so strongly in the viability of the project that their perseverance finally paid off. After 20 years of research and development by George Daniels and 5 long years of testing by Omega, the coaxial escapement is today being produced in series in the De Ville Co-Axial line of watches and stands as a future reference for the entire mechanicalwatchmaking industry.
