Caliber 9S 25th Anniversary Limited Edition
Inspired by a sea of clouds at daybreak
A new limited-edition watch commemorates the 25th anniversary of the Caliber 9S mechanical watch movement.
The new GMT watch lifts the imagination skyward with a beautiful blue dial that illustrates a sea of clouds at daybreak. In the early morning, humid air forms dense clouds that overlap to create a beautiful tapestry in the sky. The shade of blue is inspired by the sky over Mt. Iwate when it is blanketed by this sea of clouds. A rotating sapphire bezel in blue and white elevates the design while allowing for a total of three time zones to be read at once.
Inside is the Grand Seiko Caliber 9S86. Assembled at the Grand Seiko Studio Shizukuishi by skilled craftsmen and women, the Caliber 9S86 beats 10 times per second, enhancing rate stability.

A dial that expresses the beauty of the sea of clouds and sky over Mt. Iwate
The dial’s organic pattern depicts the layered sea of clouds that envelops Mount Iwate as dawn breaks. The pale blue color overlaid on the pattern gives the dial the appearance of a sea of clouds floating in a beautiful sky.
A titanium oscillating weight made light blue through anodic oxidation
The oscillating weight is a fresh sky-blue color achieved through an anodic oxidation process. Decorated with the Grand Seiko lion emblem, the oscillating weight, like the dial, calls to mind a beautiful blue sky with a sea of clouds. This creation marks the first time a Grand Seiko mechanical watch with water resistance to 20 bar has featured an exhibition case back.
