A high beat movement opens a new chapter in the history of Grand Seiko
In 1998, the creation of the 9S mechanical caliber opened a new chapter in the Grand Seiko story. In 2020, the pages turned again with the launch of a new high beat mechanical caliber, 9SA5, which, in its design and functionality, represented an advance just as important as the first 9S.
Caliber 9SA5 is more than just a new movement. It is the foundation upon which a whole new generation of Grand Seiko mechanical watches would be created. Deploying all the skills and experience gained over the past 60 years, Caliber 9SA5 is, beyond doubt, the finest mechanical movement that Grand Seiko has ever created.
