1. Is this a genuine Omega part?
Yes, this is a genuine Omega factory part (reference 7222500C70530), manufactured in Switzerland. Omega technical documentation lists 70530 specifically as the upper shock-absorber for Caliber 2500C .

The upper shock-absorber (70530) protects the balance staff from the top side, while the lower shock-absorber (70531) protects from the bottom. Omega technical documentation for Caliber 2500C lists both as separate service parts . They are not interchangeable.
