Quick TakeThe Grand Seiko SLGH017 is not your average timepiece. This isn't just a watch; it's a wearable testament to Grand Seiko's mastery, a slice of the serene Hiraniwa Plateau's nocturnal beauty for your wrist. The high-intensity titanium case and bracelet make it feel deceptively light, but don't let that fool you. The innovative Caliber 9SA5 movement is a mechanical marvel. It's a whisper-quiet powerhouse with an 80-hour power reserve that embodies efficiency, much like the silent, enduring strength of the white birch forests that inspire its design. Notice the dial – a canvas of the night, intricate and mysterious. And with that 10-bar water resistance? Go on a swim, the GS isn't bothered. This watch isn't about flashing status, it is a companion. The SLGH017 is a tribute to the brand's relentless pursuit of perfection, and an ode to the subtle yet profound beauty found in nature's quiet moments. This watch doesn't just tell time; it tells a story, inviting you to become a part of it. The intricate details, from the Zaratsu-polished case to the meticulously crafted hands, whisper tales of dedication and artistry.

DescriptionThe Grand Seiko SLGH017, a member of the Evolution 9 Collection, represents a significant advancement in horological engineering. Its case and bracelet are crafted from high-intensity titanium, contributing to an overall weight of 114 grams, ensuring a notable lightness without compromising durability. The case, with a diameter of 40.0mm, a lug-to-lug measurement of 47.0mm, and a thickness of 11.7mm, exhibits a balanced profile. The box-shaped sapphire crystal, treated with an anti-reflective coating on its inner surface, provides a clear view of the dial while enhancing scratch resistance. Furthermore, the titanium construction offers an allergy-safe metal composition. The watch features a see-through and screw-down case back and a screw-down crown, contributing to its water resistance rating of 10 bar. Additionally, the watch is rated for magnetic resistance up to 4,800 A/m.

At the heart of the SLGH017 lies the Caliber 9SA5, an automatic movement that also accommodates manual winding. This movement is characterized by its precision, with a mean daily rate of +5 to -3 seconds per day and a normal usage accuracy of +8 to -1 seconds per day. This is also due to the efficiency of the Dual Impulse Escapement and the use of twin barrels, culminating in a power reserve of approximately 80 hours. The dial, inspired by the white birch tree forests on the Hiraniwa Plateau at night, is a design element that harmonizes with the watch's technical attributes, using the iconic Zaratsu polished, distortion-free mirror finish. The watch’s hands and markers are designed for legibility and are made of the same high-intensity titanium, maintaining a consistent aesthetic and ensuring longevity. A three-fold clasp with a push-button release secures the 22mm wide bracelet. The perimeter of the band measures 192mm.
