Details:
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.
