Omega 8900 Movement Shock-Absorber Lower 7228900A70531

Product Description

The Omega 8900 Movement Shock-Absorber Lower (7228900A70531) is a genuine Omega original lower shock absorber assembly for the Caliber 8900 Master Chronometer automatic movement . This critical protective component for the lower balance staff pivot uses the proven Incabloc shock protection system, including an elastic spring, endstone, and setting (chaton).
