This is a genuine Cartier pallet fork for Caliber 1847, a Swiss‑made original component for Cartier‘s in‑house 1847 MC automatic movement. As the central element of the lever escapement, 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 1847 movement.
Genuine Cartier Part – Swiss factory‑original for Caliber 1847 MC, not a copy.
Escapement Core – Works with the escape wheel and balance to convert gear train energy into stable oscillation.
Precision Machined – Accurately cut pallet jewels (entry/exit) and pivots for efficient power transfer and low friction.
Essential for Service – Common failure point for inaccurate timekeeping, stoppage, or low amplitude.
Compatible Movement – Designed for Cartier Caliber 1847 MC automatic.

1. Is this a genuine Cartier pallet fork?
Yes. It is a Swiss factory‑original part for Caliber 1847 MC, 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. Follow the Cartier 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 (deformed or broken), replace both. Inspect both components.
5. Is regulation required after replacement?
Yes. After replacing the pallet fork, check amplitude, beat error, and rate, and adjust as needed. Use a timing machine for final verification.
