Grand Seiko Evolution 9 SLGH027 Hi-Beat 36000 – The majesty of Mount Iwate in a limited edition
Inspiration from Japanese nature
The Grand Seiko SLGH027 is a masterpiece from the Evolution 9 collection, created at the prestigious Grand Seiko Studio Shizukuishi in northern Japan. Its textured dial, in a deep light blue, is inspired by the ridges and landscapes of Mount Iwate, evoking the purity of the air and water surrounding this majestic mountain.
Ever-Brilliant Steel: beauty and durability
The case and bracelet are crafted from Ever-Brilliant Steel, an exclusive alloy with greater corrosion resistance than conventional stainless steel. Its finish combines Zaratsu polishing—a distortion-free mirror finish—with finely brushed surfaces, achieving a harmonious shine. With a 40 mm diameter, 11.7 mm thickness, and a low center of gravity design, it offers exceptional comfort on the wrist.
Calibre 9SA5: Hi-Beat precision with 80-hour power reserve
Inside beats the Hi-Beat 36000 mechanical calibre 9SA5, featuring a dual impulse escapement and dual barrel system. This advanced engineering provides an approximate 80-hour power reserve and a frequency of 36,000 vibrations per hour, ensuring precision and stability (+5 to -3 seconds per day under controlled conditions). The transparent case back reveals the delicate movement finishing, inspired by the flowing waters of the Shizukuishi River.
Legibility and comfort – Evolution 9 Style
The design follows the Evolution 9 Style principles, prioritizing beauty, legibility, and ergonomics. The bold hands and grooved indices enhance readability even in low light. The screw-down crown, 10-bar water resistance, and 4,800 A/m magnetic resistance make this a robust and reliable timepiece.
A limited edition for collectors
Limited to 1,200 pieces, the Grand Seiko SLGH027G is a true collector’s piece that pays tribute to Mount Iwate and Japanese watchmaking mastery. Each unit is engraved with its serial number on the case back, emphasizing its exclusivity.
