Grand Seiko Evolution 9 Manual-Winding Mechanical Hi-Beat 36000 80 Hours SLGW003

The Grand Seiko SLGW003G is a hand-wound mechanical timepiece from the Heritage Collection, reflecting Grand Seiko’s timeless craftsmanship and attention to detail. Its silver-white dial features a crisp, minimalist aesthetic, with slender polished hands and applied indices that deliver exceptional legibility and refined elegance. Encased in stainless steel, the watch measures 39.0 mm in diameter, 10.4 mm in thickness, and 48.7 mm lug-to-lug—dimensions that offer a balanced, comfortable fit on the wrist.

At its heart is the Caliber 9S64, a manually wound movement that provides approximately 72 hours of power reserve and a high level of accuracy under typical Grand Seiko standards. The SLGW003G is protected by a box-shaped sapphire crystal with anti-reflective coating on the inner surface, and offers 10 bar water resistance and magnetic resistance up to 4,800 A/m. The display case back allows a view of the refined movement within, while the stainless steel bracelet is secured with a three-fold clasp featuring a push-button release—culminating in a watch that seamlessly blends traditional dial design, mechanical integrity, and everyday practicality.
