This is a genuine Omega pallet fork for Caliber 8800 Co‑Axial automatic movement, part number 7228800A40010, Swiss‑made. As the core element of the Co‑Axial escapement system, it works with the escape wheel and balance wheel to convert gear train energy into precise oscillating beats, controlling timekeeping accuracy. This original factory part is the ideal replacement for watchmakers to restore stable and precise timekeeping when servicing the Caliber 8800 movement.
Genuine Omega Part – Swiss factory‑original for Caliber 8800 Co‑Axial, not a copy.
Co‑Axial Escapement Core – Works with the escape wheel and balance for efficient, low‑friction power transfer.
Precision Machined – Accurately cut pallet stones (entry/exit) and pivots for efficient escapement energy transfer.
Anti‑Magnetic – Co‑Axial components are made of anti‑magnetic materials to resist everyday magnetic fields.
Essential for Service – Common failure point for inaccurate timekeeping, stoppage, or low amplitude.
Compatible Movement – Designed for Omega Caliber 8800, 8801, 8806 (8800 series Co‑Axial automatic).

Omega Caliber 8800 series Co‑Axial automatic movements (found in Seamaster Diver 300M 8800, Aqua Terra 8800, Constellation 8800, etc.).
Repair of severe timekeeping errors, stoppage, or low amplitude not resolved by routine service.
Replacement of pallet forks with worn pallet stones, bent pivots, or detached jewels during service.
1. Is this a genuine Omega pallet fork?
Yes. It is a Swiss factory‑original part (7228800A40010) for 8800 series calibers, not a copy.
2. What are the symptoms of a damaged pallet fork?
Symptoms: very fast or slow timekeeping; stoppage or intermittent running; very low amplitude; irregular ticking noise or metallic scraping sound from the escapement.
3. What should I pay attention to during installation?
The pallet fork sits between the mainplate and the pallet bridge. Ensure both pivots drop into jewels and the pallet stones properly engage the escape wheel teeth. Apply a tiny amount of dedicated escapement oil to the pivots. The Co‑Axial escapement has stringent lubrication and clearance requirements. Follow the Omega technical guide; professional installation is strongly recommended.
4. Does the escape wheel need to be replaced at the same time?
Not always. If the escape wheel teeth are also visibly worn, replace both. Co‑Axial components are highly wear‑resistant, but if wear is observed, replace both for optimal escapement performance.
