The Grand Seiko SLGH017 is a masterpiece inspired by the enchanting white birch forests near Japan's Grand Seiko Studio Shizukuishi. Its dial mimics the organic birch texture in a subtle black hue, evoking the nighttime atmosphere of the Hiraniwa Plateau. Crafted from High-Intensity Titanium, the Evolution 9 case is a testament to meticulous artistry, boasting Zaratsu-polished and hairline-finished surfaces for a refined look. Designed with a lower center of gravity, it ensures comfortable everyday wear.

The dial is engineered for optimal readability, featuring distinct hour and minute hands. Each marker is painstakingly cut with diamonds, resulting in a highly reflective surface that captures even the faintest glimmers of light. Powering the SLGH017 is the caliber 9SA5, a Hi-beat movement with an impressive 80-hour power reserve and a precision rate of +5 to -3 seconds per day. It introduces three groundbreaking elements: the Dual Impulse Escapement, a free-sprung balance, and a horizontal gear train.

The SLGH017 seamlessly blends aesthetic allure with technical brilliance, appealing to connoisseurs who value both form and function in their timepieces. This watch stands as a testament to Grand Seiko's commitment to excellence, showcasing a harmonious fusion of natural inspiration and cutting-edge engineering.
