[Product Features]
New Design Series "Series 9"

The exterior of this model inherits the design grammar established with the 44GS in 1967, while being based on a form that lets light flow beautifully. It also incorporates the Japanese sensibility that finds beauty "between light and shadow," and is guided by a new design grammar that aims to further evolve essential legibility and wearability.
The case, finished with a distortion-free mirror surface and delicate grain by Zaratsu polishing, not only emits beautiful light and deep shadows, but also depicts the soft gradations of light that shift between them. The dial features deeply grooved indexes for a bold presence, combined with three-dimensional hour and minute hands that enhance legibility through a strong contrast. The bracelet offers a secure fit, while the case, designed to fit comfortably on the wrist with a low center of gravity, also enhances wearability.
This design series, a legitimate evolution of Grand Seiko's design grammar, will continue to be developed under the name "Series 9."
Next-Generation Grand Seiko Caliber 9SA5
This model is equipped with the Caliber 9SA5, a mechanical high-beat movement exclusive to Grand Seiko, launched in 2020. This next-generation movement employs a dual impulse escapement (a highly efficient escapement) and twin barrels (two mainsprings) to achieve a high-beat rate of 36,000 vibrations per hour, while still maintaining a power reserve of approximately 80 hours when fully wound. Its unique horizontal gear train structure also contributes to its slim design.
Caliber 9SA5 is created by experienced artisans at Grand Seiko Studio Shizukuishi, a workshop surrounded by abundant nature and overlooking the majestic Mount Iwate.
The dial depicts a majestic birch forest brimming with vitality

The flow of time is at the heart of Japanese aesthetics. The essence of time is nature itself, and human activities have been considered to be a part of nature. This model truly embodies Grand Seiko's brand philosophy, "THE NATURE OF TIME" (*1), combining an innovative movement assembled by skilled artisans to capture the essence of time with dial and movement designs inspired by the magnificent nature found around the workshop.
Near Grand Seiko Studio Shizukuishi, the manufacturing base for mechanical Grand Seiko, is one of Japan's leading areas for growing white birch trees. The mystical sight of tall, slender white birch trees standing in layers, bathed in the clear air of the plateau, evokes the beauty and strength of nature. This model depicts this magnificent birch forest with a dynamic embossed pattern and delicate coloring on the dial.
The movement, visible through the case back, is also finished in a style inspired by the natural beauty of Shizukuishi. The "Shizukuishi River Finish" with its delicate striped pattern evokes the majestic flow of the Shizukuishi River, which changes with the seasons.

Since its launch in 1960, Grand Seiko has strived to create the finest wristwatches, continuously pursuing and realizing the essential qualities of a watch, such as accuracy, beauty, and legibility, at a high level, and has made tireless progress. Since 2010, Grand Seiko has been expanding globally, earning acclaim worldwide for the highest level of performance and sophisticated design that only a truly rare manufacturer can achieve.
