1. Is this a genuine Cartier click?
Yes. It is a Swiss factory‑original part for Caliber 1847 MC, not a copy.
2. What are the symptoms of a damaged click?
Symptoms: rotor spins normally but automatic winding is very poor (low power reserve); manual winding works but automatic does not; unusual noise or clicking sound during automatic winding.
3. What should I pay attention to during installation?
The click is typically secured by a screw. Ensure the spring sits correctly in its groove and the click tooth properly engages the ratchet wheel. Follow the Cartier technical guide. Professional installation is strongly recommended.
4. Does the ratchet wheel need to be replaced at the same time?
Not always. If the ratchet wheel teeth are also worn, replace both. Try replacing the click first; if issues persist, replace the wheel.
5. Does this part fit all 1847 MC variants?
Yes. The entire 1847 MC family shares the same automatic winding module; the click is common.
