Grand Seiko Evolution 9 Mechanical Hi-Beat 36000 80 Hours SLGH027

The Grand Seiko SLGH027 is a limited-edition timepiece that captures the beauty of Mt. Iwate’s soaring ridgelines through a newly designed light-blue dial pattern. Inspired by the view from above the mountain’s slopes, this dial reflects Grand Seiko’s connection to nature, while the watch itself represents the brand’s pinnacle of mechanical watchmaking. Crafted from Ever-Brilliant Steel, which offers superior corrosion resistance and a bright, elegant sheen, the case and bracelet provide both durability and a refined presence on the wrist. With its Evolution 9 design, the SLGH027 ensures excellent legibility and comfort, while Zaratsu-polished surfaces deliver distortion-free reflections that highlight the purity of its form.

Inside, the Caliber 9SA5 high-beat movement beats at 36,000 vibrations per hour, achieving remarkable precision of +5 to -3 seconds per day with an extended 80-hour power reserve. Its Dual Impulse Escapement and twin-barrel construction represent the cutting edge of Grand Seiko’s mechanical innovation. The box-shaped sapphire crystal protects the dial, while a see-through case back reveals the beautifully finished movement, inspired by the gentle flow of the Shizukuishi River. Limited to just 1,200 pieces, the SLGH027 is a masterwork that reflects both technical excellence and the quiet beauty of the natural world.
