Created by Grand Seiko’s chief designer, Nobuhiro Kosugi, and his team, the Caliber 9S marked another milestone for this Japanese manufacturer that was born with the intention of simply offering the ideal watch. The eternal clock. The most practical, beautiful and reliable watch in the world. With a singular exterior and a design created from scratch, this watch launched for the first time in 1998 marked a before and after in mechanical watchmaking and in the firm that even redefined its legendary GS Standard to turn the new caliber into the base on which that all its movements were built and have been built ever since. Until reaching excellence, of course, in the revolutionary Caliber 9SA5 launched in 2020.

Today, that Caliber 9S that in 1998 surprised with its singular exterior and an interior marked by the precision and beauty of its new automatic movement, celebrates its 25th anniversary with two very special editions.

Faithful to its impressive but discreet character (Kosugi’s watch was suitable for daily use, even when its case and dial played with the light) and to that idea of ​​working excellence without pretensions, the piece maintains the same design and diameter conceived at its release.

It is its dials, dressed in the colors of Japan’s Mount Iwate (a stratovolcano located northwest of the city of Morioka, in Iwate Prefecture) that make the Caliber 9S 25 Anniversary Limited Edition true pieces of desire. A new obsession for collectors.

The first of the commemorative watches is silver (like that of the sea and the clouds of that beautiful mountain on cloudy days), and on its back the mass of titanium in an intense blue symbolizes the sky. And the dial of the second is light blue (the same Japanese sky, but clear) with a sunray finish and diamond-cut hands and indices. They are, of course, limited editions of 1,200 units.
