The Grand Seiko Studio Shizukuishi sits in the shadow of Mt. Iwate, where the ridges of the mountain have long inspired the brand’s craftsmanship. The SBGW323 captures this connection and has a striking purple dial color paying tribute to the kiri, the official flower of Iwate Prefecture. As light moves across the surface, the depth and texture of the dial create an ever-changing visual experience.
The 44GS, first introduced in 1967, established the design principles that define Grand Seiko today. The SBGW323 refines this legacy in a mid-sized 36.5mm case, balancing heritage with modernity. Zaratsu-polished surfaces contrast with delicate hairline finishing, while the box-shaped sapphire crystal adds a vintage touch. Paired with a stainless steel bracelet, the watch also features drilled lugs and an 18mm width for effortless customization.
Assembled by hand by the artisans of the Grand Seiko Studio Shizukuishi, Caliber 9S64 is a manual-winding mechanical movement with a 72-hour power reserve and an accuracy rating of -3 to +5 seconds per day.
The mid-size 44GS case brings a fresh dimension to Grand Seiko’s legendary 1967 design, offering a more compact yet equally striking presence. At 36.5mm in diameter, it retains the sharp, flat surfaces and distortion-free Zaratsu polishing that define the original. The result is a masterfully balanced timepiece that stays true to the Grand Seiko Style, enhancing wearability without sacrificing Grand Seiko’s unmistakable aesthetic.
Nestled beneath the towering presence of Mt. Iwate, the Grand Seiko Studio Shizukuishi has long drawn inspiration from the mountain’s distinctive form and textures. That connection comes to life in the SBGW323, where a deep purple dial—its hue inspired by the kiri, Iwate Prefecture’s official flower—serves as a bold tribute to the region. The intricate Mt. Iwate pattern, mirroring the mountain’s rugged contours, plays with light and texture, creating a dial that shifts in appearance with every glance.
Caliber 9S64 is a manual-winding mechanical movement made at the Grand Seiko Studio Shizukuishi, offering a 72-hour power reserve and precision accuracy of -3 to +5 seconds per day. It undergoes rigorous testing in six positions, surpassing chronometer standards. The movement is also known for its beautiful finishing, showcasing Grand Seiko’s dedication to craftsmanship and mechanical excellence.
