The Cartier Caliber 1847 Winding Pinion is an original Cartier part designed for the Cal. 1847 automatic movement. As a key gear within the winding system, the winding pinion connects the crown to the movement, ensuring smooth and reliable hand‑setting and winding. This component is an essential replacement for maintaining the precision and durability of Cartier watches powered by the 1847 caliber.
Genuine Cartier Part – Swiss factory‑original for Caliber 1847, not a copy.
Winding System Core – Connects the crown to the movement gear train, transmitting manual winding and setting torque.
Precision Machined – Accurate gear teeth for smooth winding and crisp keyless feel.
Essential for Service – Replace when manual winding slips, spins freely, or setting feels sticky.
Compatible Movement – Designed for Cartier Caliber 1847 MC automatic.

1. Is this a genuine Cartier winding pinion?
Yes. It is a Swiss factory‑original part for Caliber 1847 MC, not a copy.
2. What are the symptoms of a damaged winding pinion?
Symptoms: the crown spins freely when winding (no resistance); cannot wind the mainspring; hands do not move or slip when setting time; vague or sticky keyless feel.
3. What should I pay attention to during installation?
The winding pinion sits on the stem. Clean the keyless works before assembly. Test smooth winding and setting mode switching after installation. Professional help is recommended.
4. Does the clutch wheel need to be replaced at the same time?
Not always. If the clutch wheel teeth are also visibly worn (rounded), replace both. Inspect both components.
5. Does this part fit other Cartier calibers like 1904 MC?
No. The 1847 keyless works are different from 1904 – not interchangeable.
