Features

Representing a novel interpretation of the iconic Mt. Iwate pattern, the dial of the SLGH027 captures the grandeur of the mountainscape from a fresh perspective, rendered in a serene light-blue hue that reflects the clarity of the surrounding air and water. Limited to just 1,200 pieces, this exclusive timepiece is defined by Grand Seiko’s enduring commitment to craftsmanship and innovation.

Crafted in the Evolution 9 Style, the case blends Zaratsu polishing with delicate hairline finishes for a refined aesthetic. Ever-Brilliant Steel enhances its durability and luminous finish, while bold indexes and powerful hands ensure exceptional legibility.

At its heart, the high-beat Caliber 9SA5 delivers precision with a frequency of 36,000 vibrations per hour and an 80-hour power reserve. Its advanced Dual Impulse Escapement and twin-barrel design maximize efficiency, while the movement’s finishing, inspired by the gentle flow of the Shizukuishi River, merges technical mastery with artistic refinement.
