Grand Seiko Heritage Collection "Icefall" Hi-Beat 36000 –Ref. SBGH347

The Frozen Splendor of Mount Iwate

Immerse yourself in the dramatic, mid-winter landscape of northern Japan with the Grand Seiko Heritage Collection "Icefall" SBGH347. This exceptional mechanical timepiece captures the breathtaking, fleeting beauty of a completely frozen waterfall encountered in the dead of winter on Mount Iwate—the imposing volcanic peak visible through the windows of the Grand Seiko Studio Shizukuishi.

The dynamic, heavily textured dial features a specialized, ridge-grained pattern that beautifully mirrors the layered, sheer ice formations of a cascading waterfall frozen solid in time. Brought to life in a striking, icy-blue color palette, the dial mimics the way sunlight passes through deep, compressed sheets of winter ice. The clean, date-inclusive layout features multi-faceted, diamond-cut hands and grooved indices that give the face incredible depth, ensuring the crisp legibility that defines the Grand Seiko Style.

High-Intensity Titanium and Classic Case Geometry

The SBGH347 features a classic 40mm mechanical case design crafted from Grand Seiko’s proprietary High-Intensity Titanium. This advanced alloy is 30% lighter than standard stainless steel and provides superior resistance to scratches, rust, and corrosion, offering an incredibly comfortable, lightweight feel on the wrist. Every angular facet of the case is treated with hand-executed Zaratsu mirror polishing, yielding flawless, distortion-free surfaces that alternate seamlessly with fine, hairline-brushed flanks.

The watch is anchored by an integrated High-Intensity Titanium three-link bracelet with a secure three-fold clasp and push-button release, perfectly balancing everyday sporty durability with high-luxury refinement.

Assembled by Hand: 10 Beats Per Second

Beating within this winter-inspired masterpiece is the legendary, in-house Caliber 9S85 automatic movement. Hand-assembled by elite master watchmakers at the Studio Shizukuishi, this high-performance mechanical hi-beat caliber operates at an astonishing frequency of 36,000 vibrations per hour (10 beats per second). This rapid cadence allows the seconds hand to sweep with mesmerizing, fluid continuity while providing a robust 55-hour power reserve and an exceptional static daily accuracy rating of +5 to -3 seconds. The inner workings can be fully appreciated through a see-through sapphire exhibition case back, completing a timepiece built for serious horological purists.
