Omega 8900

Calibre 8900 is the first of a family of automatic Co-Axial watch movements from Omega. It will replace Cal. 8500.

In 2007, Omega introduced the first in-house Co-Axial movement family, Cal. 8500. This movement was redesigned and the new Cal. 8900 launched at BaselWorld in 2015. That movement was shortly joined by a family of new movements, with Omega making it known that this would replace the Cal. 8500 family. The luxury-finished Cal. 8901 was the first of Omega's movements to meet the METAS certification.

Cal. 8900 features two barrels in series, providing a power reserve of 60 hours. It uses a free-spring balance and silicon balance spring, making it resistant to magnetic fields up to 15,000 Gauss. Like its predecessor, it operates at 25,200 A/h rather than the more-common 28,800 A/h.
