George Daniels invented the design; Omega adapted it for industrial production and began using it in its watches in 1999. The lower-friction design is intended to reduce lubrication needs, but it does not make a watch maintenance-free or establish a guaranteed service interval.
What an escapement does
A mechanical watch’s balance oscillates back and forth to regulate timekeeping. The escapement meters energy from the movement to sustain that oscillation, while also allowing the gear train to advance in controlled increments. In Omega’s description, the Co-Axial design changes how the parts interact as they transmit energy, with the aim of reducing friction.
How the Co-Axial design differs in principle
Omega and Swatch Group explain the design rationale in terms of fewer or reduced contact surfaces at the energy-transmitting interactions. Less sliding contact is intended to mean less friction and a reduced need for lubrication. These are design goals and corporate performance claims, not a guarantee that every Co-Axial watch runs longer between services or keeps better time in every owner’s use.
That distinction matters: the available corporate material does not give a universal service schedule, a controlled real-world accuracy comparison, or a quantified improvement over a conventional lever escapement. Claims such as “never needs oil,” “maintenance-free,” or “twice as accurate” go beyond the evidence.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Co-Axial and conventional lever escapements: what can be compared
| Aspect | Co-Axial | Conventional lever escapement |
|---|---|---|
| Contact and friction rationale | Designed to reduce friction at the interacting parts that transmit energy, according to Omega. | The sources cited here do not provide a technical comparison of contact surfaces or friction. |
| Lubrication rationale | Lower friction is intended to limit oiling needs; Swatch Group says this can reduce servicing needs. | The sources cited here do not quantify lubrication needs against Co-Axial. |
| Production history | Daniels presented the design in 1976; Omega adopted it for production watches in 1999. | The sources cited here do not set out a corresponding production-history comparison. |
| Service interval and precision | No universal interval or numerical precision advantage is established by the cited sources. | No equivalent interval or comparative precision figure is stated in the cited sources. |
How the escapement reached Omega watches
The idea originated with independent watchmaker George Daniels, who presented the Co-Axial escapement in 1976. Fondation Haute Horlogerie records ETA integrating it into a series-production movement in 1996. In 1998, Daniels and his protégé Roger Smith made a limited series of 50 Millennium wristwatches using early Omega movements incorporating the escapement.
Omega adopted the technology in 1999 with calibre 2500. Swatch Group’s development timeline then records the Co-Axial chronograph calibre family 3313 in 2005, calibre 8500 in 2007, and the smaller-watch calibres 8520/8521 in 2008. Swatch Group describes the 8500 as Omega’s first movement built entirely around the escapement and says its development involved 202 components. Those figures and characterizations are Swatch Group’s account.

What Co-Axial does not tell you about a watch
Co-Axial describes the escapement, not every capability of the complete movement or watch. Anti-magnetic properties and Master Chronometer certification are separate advances or standards; the presence of a Co-Axial escapement alone does not establish either. Check the specifications for the particular model and calibre rather than inferring those attributes from the escapement name.
Omega’s larger historical framing is that the Co-Axial followed a 250-year period without a practical new mechanical-watch escapement. That is Swatch Group’s characterization of watchmaking history, not an independently validated measurement.
