Grand Seiko, founded in 1960 with the aim of creating the finest wristwatches, has continued to pursue the essential qualities of a wristwatch—accuracy, beauty, and legibility—at a high level. The "Seiko Style" was established with the release of the "44GS" in 1967, and in 2020, marking the 60th anniversary of the brand's founding, the company announced the revolutionary mechanical movement "Caliber 9SA5," which will lead the next generation, as well as the Spring Drive movement "Caliber 9RA5." The "Caliber 9RA2," released in 2021, has the same performance as the "Caliber 9RA5," but by placing the power reserve indicator on the back and lowering the mounting position of the hands, the company has succeeded in making the case thinner.
≪Product Features≫
Uses "Ever Brilliant Steel," boasting the world's highest level of corrosion resistance
For the first time, Grand Seiko has adopted "Ever Brilliant Steel" (※1), which boasts the world's highest level of corrosion resistance, not only for the case but also for the bracelet. This advanced material, which is whiter and more beautiful than conventional stainless steel, harmonizes with the evolved mechanical movement, "Caliber 9SA5," and the Spring Drive movement, "Caliber 9RA2," and beautifully enhances the 55-year-old "44GS" design. (※1) This material has a PREN (Pitting Resistance Equivalent Number) value 1.7 times higher than the stainless steel commonly used in luxury watches. PREN is a widely used index for evaluating the corrosion resistance of metals.
A dial that evokes the passage of time
The mechanical model features a dark blue dial, while the Spring Drive model features a dark gray dial, featuring a deep, intricate embossed pattern. This expresses the eternal flow of time, like the cycle of stars in the endless universe. Grand Seiko will continue to carry on the "Seiko Style" design principles established 55 years ago into the future.
Intricate finish visible through the case back
The case backs of the models reveal their different personalities, inspired by the rich nature of Shizukuishi and Shinshu, where they are each manufactured. The Caliber 9SA5 features a "Shizukuishi River finish" inspired by the gentle ripples of the Shizukuishi River, while the Caliber 9RA2 features a "Shinshu Hoarfrost finish" that evokes the frost that can be seen in the Shinshu region during the harsh winter months.
