Quick TakeOkay, picture this: you've got the SLGH021 strapped on. This isn't just some timepiece; it's a chunk of the Genbi Valley's majesty, right there on your wrist. That light-green dial? It's like gazing into a serene, verdant landscape, framed by the lustrous Ever-Brilliant Steel. It's got that high-beat 9SA5 movement ticking away, smooth as silk, offering 80 hours of get-up-and-go without a second thought. And get this, it's tougher than it looks, with that steel case shrugging off corrosion like it's nothing. At 40mm, it sits just right, not too flashy, but definitely a head-turner. It's like Grand Seiko took the heart of Iwate's natural splendor, mixed it with some top-shelf engineering, and wrapped it around your wrist. A limited edition, yeah, but it feels limitless in what it brings to the table. A piece that whispers tales of scenic beauty and whispers, "I'm a marvel of watchmaking."

DescriptionThe Grand Seiko SLGH021 is encased in Ever-Brilliant Steel, a material selected for its exceptional corrosion resistance, the highest among stainless steels globally, and its distinct white shine that complements the light-green dial. The watch's case measures 40.0mm in diameter, with a lug-to-lug length of 47.0mm and a thickness of 11.7mm. It features a box-shaped sapphire crystal with an anti-reflective coating on the inner surface, ensuring clarity and durability. The case back is a see-through, screw-down design, also made of Ever-Brilliant Steel and sapphire crystal, allowing a view of the intricate Caliber 9SA5 movement. The watch is water-resistant up to 10 bar and has a magnetic resistance of 4,800 A/m. Its bracelet, matching the case in material and finish, features a 22mm width and a secure three-fold clasp with a push-button release. Each watch's individual serial number and "LIMITED EDITION" designation are engraved on the case back, adding to its exclusivity. It weighs 169g.

Powering the SLGH021 is the Caliber 9SA5, an automatic movement with manual winding capability. This ten-beat movement boasts an impressive power reserve of approximately 80 hours when fully wound. Its precision is notable, with a mean daily rate of +5 to -3 seconds per day under controlled testing conditions. In normal use, the accuracy is expected to be within +8 to -1 seconds per day. The movement is meticulously measured in six positions over 12 days before being assembled into the case to ensure its high performance. The design of the movement, visible through the sapphire case back, showcases the craftsmanship and attention to detail that Grand Seiko is known for. The screw-down crown adds an extra layer of protection, securing the inner mechanism from water and dust ingress.
