Grand Seiko SLGH005

First revealed in March 2020, 9SA5 is an entirely new high beat mechanical movement. Developed from scratch exclusively for Grand Seiko, Caliber 9SA5 will be the foundation upon which a whole new generation of Grand Seiko mechanical watches will be created. Nine years in development and deploying all the skills and experience that Grand Seiko has gained over the past 60 years, 9SA5 is without doubt the finest mechanical caliber Grand Seiko has ever created.
