A dial inspired by winter skies over Shinshu.
Available December 2025
The SBGX357 captures the serene beauty of snow swept by mountain winds beneath a clear blue sky. Its light blue dial, delicately textured to evoke the surface of wind-carved snow, mirrors the tranquil winter landscapes surrounding the Shinshu Watch Studio—home of Grand Seiko’s quartz craftsmanship. This distinctive hue, reflecting snow under a bright sky, gives rise to the watch’s affectionate nickname: the “Skyflake.” A tempered blue seconds hand glides gracefully across the dial, embodying the quiet, measured passage of time in Shinshu’s winter.
Design and craftsmanship: Encased in a 37mm body and bracelet crafted from High-Intensity Titanium—30% lighter than stainless steel yet more resistant to corrosion and wear—the SBGX357 offers both refined elegance and enduring durability. The watch’s harmonious blend of lightness, resilience, and subtle beauty reflects Grand Seiko’s dedication to artistry in everyday wear.
Precision at its core: Caliber 9F62 - Beneath the dial beats the renowned Grand Seiko Quartz Caliber 9F62, a movement celebrated for its remarkable accuracy and robust engineering. It incorporates innovations rarely found in standard quartz watches, including the Instant Date Change Mechanism, Backlash Auto-Adjust Mechanism, and a regulation switch for fine-tuning performance.
Even after more than 25 years, Caliber 9F62 continues to set the standard for high-performance quartz movements, offering annual accuracy within ±10 seconds and a battery life of approximately three years. In addition to precise timekeeping, it features a crisp date display, combining reliability with understated sophistication.
