## FAQs
**1. Is this a genuine Rolex balance spring or an aftermarket part?**
This is an **aftermarket replacement part** made in China, not a genuine Rolex balance spring. It is designed as a compatible alternative for repair purposes.
**2. Will this balance spring fit my 3186 movement?**
It is **specifically designed** for 3186-type movements. However, due to variances in aftermarket parts, we recommend **professional verification** of compatibility before installation.
