The SLGW007 features a textured navy dial inspired by the bark of a birch tree under moonlight, with slimmed and elongated grooved indexes and narrowed multifaceted lugs for a refined, dress-watch profile.
At its heart is the manual-winding Caliber 9SA4, delivering an 80-hour power reserve through a Dual Impulse Escapement and twin barrels. The Free-sprung Balance and overcoil hairspring ensure stability and precision, while nearly 40 percent of the base movement has been designed to enhance the tactile winding experience. The refined click, shaped like a wagtail, pays homage to Morioka, home of the Grand Seiko Studio Shizukuishi.
The stainless steel case measures 38.6mm in diameter and 9.95mm thick, offering a comfortable fit with a lowered center of gravity. A box-shaped sapphire crystal and calf leather strap complete the watch, blending technical mastery with understated elegance.
The dial pattern of SLGW007 is rendered in a deep navy hue, evoking the sight of birch trees illuminated by moonlight. This interplay of texture and color creates a dial that shifts in character with the light, embodying both serenity and depth.
The SLGW007 carries forward the history of the 1967 44GS. Refined and hand-wound, it features elongated grooved indexes, narrowed multifaceted lugs, and a stainless steel case. With a sleek 38.6mm diameter and just 9.95mm thickness, the design ensures comfort, stability, and the graceful proportions expected of Grand Seiko’s Evolution 9 style.
The manual-winding Caliber 9SA4 delivers an 80-hour power reserve through Grand Seiko’s Dual Impulse Escapement and twin barrels.
