This is a genuine Omega escape wheel for Caliber 8800, part number 7228800A30039, Swiss‑made and brand new. As a core component of the Co‑Axial escapement system, it transmits power from the gear train to the balance wheel and controls the regular release of energy, making it critical for timekeeping accuracy and stability. It is intended for the service and repair of the Omega Caliber 8800 series Co‑Axial automatic movements.
Genuine Omega Part – Swiss factory‑original for Caliber 8800, not a copy.
Co‑Axial Escapement Core – Unique Omega technology that reduces friction, extends service intervals, and improves accuracy and stability.
Precision Engineering – Special materials and geometry for efficient power transmission and release.
Essential for Service – A common failure point for inaccurate timekeeping, stoppage, or low amplitude.
Compatible Movement – Designed for Omega Caliber 8800 Co‑Axial automatic (and variants 8801, 8806, etc.).

Omega Caliber 8800 Co‑Axial automatic (found in Seamaster, De Ville, Constellation collections).
Omega Caliber 8801 (precious metal version with 18K gold rotor) and 8806 (no‑date).
Repair of severe timekeeping errors, stoppage, or low amplitude not resolved by routine service.
Replacement of escape wheels with worn teeth, bent pivots, or damaged jewel holes during service.
1. Is this a genuine Omega escape wheel?
Yes. It is a Swiss factory‑original part (7228800A30039) for Caliber 8800, not a copy.
2. What are the symptoms of a damaged escape wheel?
Symptoms: very fast or slow timekeeping; stoppage or intermittent running; very low amplitude; irregular ticking noise.
3. What should I pay attention to during installation?
The escape wheel sits between the mainplate and the escape bridge. Ensure both pivots drop into jewels and the teeth properly engage the pallet fork. Follow the Omega technical guide. Professional installation is strongly recommended.
4. Does this part fit other Omega calibers like 8900?
No. Although both are Co‑Axial, the 8900 series uses different escape wheel dimensions – not interchangeable.
5. Is regulation required after replacement?
Yes. After replacing the escape wheel, check amplitude, beat error, and rate, and adjust as needed. Use a timing machine for final verification.
