Inspired by the mysterious beauty of white birch forests after dark, the SLGH029 features a richly textured dark gray to black dial that captures the tranquil nighttime landscape surrounding the Grand Seiko Studio Shizukuishi, the renowned home of Grand Seiko mechanical watchmaking. The dial’s intricate pattern and deep dark finish evoke the silhouette of birch trees emerging from the darkness, creating a striking and sophisticated aesthetic.
Powering this exceptional timepiece is the Grand Seiko-exclusive Hi-Beat Caliber 9SA5, an advanced automatic movement engineered for outstanding precision and performance. Equipped with the innovative Dual Impulse Escapement and twin-barrel architecture, the movement operates at a high frequency of 36,000 vibrations per hour while delivering an impressive power reserve of approximately 80 hours when fully wound.
The case and bracelet are crafted from High-Intensity Titanium, a lightweight yet highly durable material that offers a brighter appearance than conventional titanium along with exceptional scratch and corrosion resistance. The bracelet design has been equipped with a more dramatic taper and micro-adjustable clasp to enhance wearing comfort without use of tools.
Combining cutting-edge mechanical watchmaking, innovative movement technology, and nature-inspired design, this Grand Seiko luxury timepiece is a remarkable choice for collectors seeking a premium high-beat watch with distinctive Japanese craftsmanship.
Born from the relentless pursuit of the perfect luxury timepiece, the Evolution 9 Style embodies a refined design language that builds upon the iconic Grand Seiko Style established in 1967. Blending contemporary horological innovation with the brand’s rich heritage, the Evolution 9 collection represents a bold evolution in Japanese watchmaking, delivering exceptional legibility, comfort, and craftsmanship while remaining true to the enduring principles of Grand Seiko.
Inspired by the moonlit white birch forests of Iwate Prefecture, home to the Grand Seiko Studio Shizukuishi, this striking dial reinterprets the iconic White Birch pattern in a rich black tone. Its dynamic texture evokes the depth of towering birch trunks illuminated beneath the night sky, capturing both the strength and serenity of Japan’s natural landscape. Crafted in lightweight High-Intensity Titanium, the case and bracelet complement the dark dial with a refined luster, showcasing Grand Seiko’s mastery of design, craftsmanship, and nature-inspired watchmaking.
The bracelet's newly developed three-step micro-adjustment clasp enables tool-free sizing in 2mm increments, ensuring a perfect and comfortable fit on the go.
Crafted from high-intensity titanium, the case and bracelet are not only 30% lighter than stainless steel but also more resistant to scratches, ensuring durability without compromising comfort.
The exceptional Caliber 9SA5 is a high-beat movement operating at 36,000 vibrations per hour with an impressive 80-hour power reserve. Its Dual Impulse Escapement and twin-barrel design enhance efficiency, while the finely finished surfaces echo the rippling waves of the Shizukuishi River, seamlessly blending technical mastery with artistic elegance.
