The term Co-Axial represents a specialized watch escapement exclusive to Omega that was developed in 1970 by British horologist and watchmaker George Daniels.

The Swiss Lever escapement has been the standard in horology for hundreds of years.

Daniels brought his desire to industrialize his escapement to many Swiss manufacturers and he was ultimately denied.

Omega in 1999 took on Daniels design with the insight of Nicolas Hayek who saw Omega as a brand of innovation and creativity who would rise to the top of the Swiss horological spectrum with the production of the co-axial escapement.

In connection with the launch of the film, Omega released a 007-special of the Professional 300M, featuring the 007-gun logo on the second hand and the rifle pattern on the watch face, this being a stylized representation of the gunbarrel sequence of Bond movies.

Omega released a second James Bond limited edition watch in 2006.

1120 (finished chronometer grade ETA 2892-A with two extra jewels) A, B, and C are similar two tier co-axial movements, but C is the first version to solve certain problems prevalent in A and B.

For example, the vibrations per hour were originally 28,800 (standard for most Swiss watches with Swiss Lever Escapements) but later lowered to 25,200 (7 vs 8 v beats a second).

The Swiss lever, although the mainstay in the industry, has the capability to be strong on energy conservation but needs considerable lubrication between the impulse pallet and the escape wheel teeth due to sliding friction.With the co-axial escapement, the impulse is done with a push to the jewels rather than a sliding fashion.In this design the work is divided between two major wheels of the escapement.In most of Brosnan's 007 films, the helium release valve is transformed into improbable hidden gadgets such as a laser cutter (Golden Eye) or remote detonator (Tomorrow Never Dies).The main reason for the switch to the Omega Diver 300M for the Bond franchise is because of Lindy Hemming, a British woman, in charge of costume/wardrobe for the new movies.This causes considerable wear on the lubrication over time and may cause wear on the pallet or escape wheel.
