Detached escapement
Co-axial escapement
VerifiedA three-level escape wheel and auxiliary lever transmit impulse through largely radial rather than sliding contact, reducing the sliding friction that consumes lubricant in a conventional Swiss lever escapement.
Schematic arrangement
How it is laid out
Outline schematic only, drawn to show the characteristic arrangement of wheel, locking member and oscillator. It is not a dimensioned working drawing and should not be used for setting up or repairing a movement.
Advantages
- Reduced friction at the impulse faces
- Longer intervals between servicing in principle
- A genuine twentieth-century structural innovation rather than a lever refinement
Drawbacks
- More complex and costly to manufacture
- Long associated mainly with Omega's proprietary production
Attribution and period
Developed by George Daniels from the 1970s–1980s; introduced commercially by Omega from 1999
Horological firsts are frequently contested. Where an invention is attributed to a named maker, that attribution is recorded as such rather than treated as settled fact.
How to recognise it
- A three-level escape wheel with two toothed tiers on a common axis, plus a small transmission wheel.
- A lever with three pallet stones rather than two.
- Marked as a co-axial calibre on Omega movements from 1999 onwards.
Servicing and conservation
Setting the co-axial escapement requires the manufacturer's tools, specified oils and documented procedures; it is not a bench improvisation. Have it serviced by a watchmaker with current co-axial training or by the manufacturer.
Work on an antique escapement by a qualified watchmaker or clockmaker. Conservation of original parts is preferred to replacement wherever the object will still run.
