A new Hi-Beat limited edition channels Mt. Iwate wrapped in a sea of clouds. It’s been 25 years since Grand Seiko introduced its landmark 9S, a movement born of uncompromising desire for the highest precision in mechanical watchmaking. When the 9S debuted in the SBGR001 in 1998, it ushered in a new era for Grand Seiko and it laid the groundwork for the many mechanical watchmaking achievements that would unfold over the next quarter-century. These ranged from the first 9S Hi-Beat models to the more recent introduction of 9SA5, the most advanced Hi-Beat Grand Seiko movement to date. This year, a new limited edition commemorates the pivotal introduction of 9S and symbolizes the continued evolution of this movement family over the last two and a half decades. And it does so in the form of a moderately sized wristwatch that respects the diameter of the 1998 original.
