The Omega Caliber 2500 was developed by Omega in the 1990s. In 1993, Omega purchased the patent for the Co-Axial escapement from English master watchmaker and inventor George Daniels. The Co-Axial Escapement was the first practical new mechanical watch escapement invented for mass market in 250 years. Omega began work to fit the Co-Axial Escapement to their Cal. 1120<\/a> movement. The 1120 was basically a decorated version of the reliable Eta 2892-A2 movement. Omega spent the next six years developing and improving the movement to fit and utilize the larger escapement. In 1999 Omega released their first watches to the public with the Omega Cal. 2500.<\/p>\n

The Co-Axial escapement has two escape wheels mounted together to release the torque from the main spring. Because there are two wheels working in conjunction with added jewels, there is less friction. No longer are there two jewels sliding along the teeth of a single wheel, but now are three that just catch the edge of the teeth on two wheels. This means less friction in the escapement, thus, longer periods between services.<\/p>\n

Omega has put together a short informative video and is worth your attention to better understand this innovation.<\/p>\n
