## FAQs
**1. Is this a genuine Omega part?**
Yes, this is a **genuine Omega factory part** (reference 7222500D20010), manufactured in Switzerland. The 2500D is the fourth and final evolution of the 2500 family, featuring a 3‑level Co‑Axial escapement .
**2. What is the difference between 2500D and 8500 barrel systems?**
The **2500D uses a single mainspring barrel** with a 48‑hour power reserve, while the **8500/8900 use dual series‑coupled barrels** providing 60 hours of power reserve . The dual‑barrel system offers longer power reserve and helps reduce timing variations due to isochronism, but the single barrel of the 2500D has proven reliable and maintains excellent accuracy to the end of its power reserve .
**3. Is the 7222500D20010 compatible with earlier 2500A/B/C versions?**
According to Omega technical documentation, the **2500D barrel may be compatible with later 2500C versions**, but it is not universally backward compatible with earlier A and B versions due to the significant changes made in the D version, including the redesigned tri‑level escapement. Please verify your movement version before ordering.
