This is a genuine Cartier intermediate wheel for Caliber 1847, a Swiss‑made original component for Cartier‘s in‑house 1847 MC automatic movement. Positioned between the center wheel and the third wheel (or for specific power transmission), the intermediate wheel ensures smooth power transfer from the mainspring barrel to the escapement, directly affecting timekeeping stability and accuracy. This original factory part is the ideal replacement for watchmakers to restore smooth power transmission when servicing the Caliber 1847 movement.

1. Is this a genuine Cartier intermediate wheel?
Yes. It is a Swiss factory‑original part for Caliber 1847 MC, not a copy.
2. What are the symptoms of a damaged intermediate wheel?
Symptoms: very slow running or stoppage; hands move weakly after winding; unusual noise or hesitation in the gear train.
3. What should I pay attention to during installation?
The intermediate wheel sits between specific train wheels. Ensure both pivots drop into jewels and the teeth mesh correctly. Follow the Cartier technical guide. Professional installation is strongly recommended.
4. Does this intermediate wheel fit other Cartier calibers like 1904 MC?
No. The 1847 has a different gear train layout and dimensions – not interchangeable.
