Grand Seikoさんのインスタグラム写真 - (Grand SeikoInstagram)「Grand Seiko 60th Anniversary Limited Edition Mechanical Hi-beat 36000 80 Hours, SLGH002. Today, the pages turn again with the launch of a new high beat mechanical caliber, 9SA5, which, in its design and functionality represents an advance just as important as the first 9S. 9SA5 is more than just a new caliber. It is an entirely new movement and the foundation upon which a whole new generation of Grand Seiko mechanical watches will be created. Deploying all the skills and experience we have gained over the past 60 years, beyond doubt, the finest mechanical caliber that we have ever created. The precision, power and slimness of Caliber 9SA5 are the result of the radical re-design of three key structures and some components within them for which several patents are either already granted or pending.
