1. Is this a genuine Cartier bridge screw?
Yes. It is a Swiss factory‑original part for Caliber 1847 MC, not a copy.
2. What are the symptoms of a damaged or missing bridge screw?
Symptoms: a loose bridge can cause gear pivots to misalign, leading to movement stuttering, stoppage, or inaccurate timekeeping; severe cases may damage the gear train.
3. How do I select the correct bridge screw?
Bridge screws may vary in length and thread specification by position. Refer to the Cartier technical guide or compare with the original screw removed. This product is a general type; verify specific application.
4. What should I pay attention to during installation?
Use a properly fitting precision screwdriver and apply even, moderate torque. A torque‑controlled screwdriver is recommended. Professional watchmaker assistance is strongly advised.
5. Should I use threadlocker?
Usually not. The original screw design has sufficient self‑locking properties. If it feels loose after multiple reuses, a tiny amount of low‑strength threadlocker (e.g., Loctite 222) may be applied.
