## Product Description
The **Omega 2500B Movement Escape Wheel (7222500B30039)** is a genuine Swiss-made component for the **Omega Caliber 2500B** Co‑Axial automatic movement. As a critical part of the 2‑level Co‑Axial escapement system, this escape wheel works with the pallet fork and co‑axial wheel to transmit impulses from the gear train to the balance, enabling stable energy transfer and timekeeping. The 2500B was the second evolution of the 2500 family, retaining the 28,800 vph beat rate of the original A version.

**2. What is the difference between 2500B and later 2500C/D versions?**
The 2500B uses a **2‑level Co‑Axial escapement** with a **28,800 vph** beat rate. The 2500C reduced the frequency to 25,200 vph and modified the gear train to address power issues, while the 2500D introduced a **3‑level escapement** that fundamentally resolved reliability concerns .
**3. Is the 2500B escape wheel compatible with 2500C or 2500D?**
No. The 2500B uses its own specific escape wheel (30039). Parts are **not interchangeable** between versions due to the significant redesigns in C and D, including changes to beat rate, gear train, and escapement geometry .
