Grand Seiko Sport Collection Calibre 25th Anniversary Limited Edition 9S SBGJ275

A dial that expresses the beauty of the sea of clouds and sky above Mount Iwate

The dial depicts the sea of clouds enveloping Mount Iwate at dawn. The pale blue color superimposed on the motif gives the dial the appearance of a sea of clouds floating in a clear sky.

Titanium oscillating weight blued by anodic oxidation

The oscillating weight is a sky-blue color obtained through an anodic oxidation process. Decorated with the Grand Seiko lion emblem, the oscillating weight, like the dial, evokes a magnificent blue sky with a sea of clouds. The SBGJ275 is the first Grand Seiko mechanical timepiece with 20-bar water-resistance.

Hi-Beat 36000 GMT mechanical movement

The watch houses the Hi-Beat 36000 GMT 9S86 mechanical caliber, which features automatic winding and high resistance to interference, guaranteeing a high level of precision on the wrist.

A limited edition GMT watch celebrating the 25th anniversary of the 9S mechanical caliber.

This GMT watch is adorned with a dial that evokes the sea of clouds sometimes visible at dawn, when dense clouds form in the still, humid air and superimpose themselves in a magnificent tapestry. The blue color is inspired by the sky over Mount Iwate, the peak visible from the Grand Seiko Studio Shizukuishi, when it is shrouded in this sea of clouds.
A rotating two-tone sapphire bezel enhances the design, while allowing simultaneous reading of three time zones.

Assembled at the Shizukuishi Studio by skilled craftsmen, the 9S86 Hi-Beat 36000 GMT caliber ensures exceptional precision thanks to its frequency of 36,000 vibrations per hour, or ten vibrations per second, or 5 Hz.
