The Lush Green of the Tsuyu Rainy Season The defining feature of this U.S. Exclusive timepiece is its breathtaking, textured dial inspired by Tsuyu—the early summer rainy season in northern Japan. The rain brings life to the dense forests and fertile rice fields that surround Mt. Iwate, the majestic peak visible right outside the windows of the Grand Seiko Studio Shizukuishi. Captured in an incredibly unique, organic green hue that carries subtle gray and iridescent undertones, the famous "Mt. Iwate" ridge-patterned dial shifts color dynamically from a deep forest shade to a bright verdant tone depending on how the light catches it. Perfect Mid-Size Proportions of the 44GS Case The SBGW311 masterfully balances historic legacy with modern comfort by presenting the iconic 1967 44GS case geometry in a refined, downsized execution. Measuring a highly wearable 36.5mm in diameter and a slim 11.6mm in thickness, this model completely rethinks mid-century elegance for the contemporary collector. The multi-faceted stainless steel case relies on sweeping, hand-applied Zaratsu mirror-polished planes that meet sharply with flawless hairline brushed surfaces, creating the dramatic play of light and shadow that defines the "Grand Seiko Style." The Mechanical Intimacy of the Caliber 9S64 To maintain its compact, wrist-hugging profile, the watch is driven by Grand Seiko's in-house Caliber 9S64, a precise, high-performance manual-winding movement. Hand-assembled and tested rigorously in six separate positions, this caliber offers an accuracy rating of +5 to -3 seconds per day when static. Because it utilizes a single, highly uniform mainspring, it guarantees a robust 72-hour (3-day) power reserve, letting you set it aside for the weekend without missing a beat while enjoying the intentional, tactile ritual of winding your watch by hand.
