Watch Description
Most winters, the water of Lake Suwa freezes over and, most years, a long ridge appears in the ice from one side of the lake to the other. Tradition has it that this is the ‘Omiwatari’ or where the Gods walk out over the ice.
True or not, the legend has inspired the craftsmen and women at the nearby Shinshu Watch Studio to create a dial of exquisite subtlety for this hand-winding Spring Drive timepiece. It has the color, feel and texture of the snow-covered ice on Lake Suwa.
The movement is Spring Drive Caliber 9R31 which has the Dual Spring Barrel that delivers a power reserve of 72 hours when fully wound. Its exquisite finishing is visible through the exhibition case-back along with the power reserve indicator.

# Grand Seiko Elegance Omiwatari SBY007G Review by A.I. WatchMetrics
## Watch Summary
The Grand Seiko Elegance Omiwatari SBY007G is a pinnacle dress watch in rose gold, showcasing a textured white dial inspired by the mystical Omiwatari ice cracks on Japan's Lake Suwa, housed in a flawlessly Zaratsu-polished 40mm case, powered by the manual-wind Hi-Beat Caliber 9S64 offering 72 hours of power reserve and exceptional accuracy, ideal for sophisticated collectors seeking timeless Japanese refinement over ostentation.
## Overall Watch Rating: 8.3/10.0
**Dials & Design Metric (9.9/10.0)** - The Omiwatari dial's intricate ice-like texture combined with mirror-polished lugs elevates it above traditional Patek Philippe dress watches in poetic artistry.
**Material Metric (9.8/10.0)** - Premium 18K rose gold with dual-sided AR sapphire and masterful Zaratsu finishing matches the material excellence of A. Lange & Söhne.
**Rarity Metric (9.7/10.0)** - Limited to only 38 pieces worldwide, its scarcity rivals boutique independents like Laurent Ferrier.
**Movement Metric (9.6/10.0)** - Caliber 9S64's high-beat precision, 28 jewels, and Geneva-level finishing outperforms many Swiss automatics in reliability.
**Brand Metric (9.4/10.0)** - Grand Seiko's blend of heritage and innovation secures its place alongside Rolex in the luxury pantheon.
**History & Innovation Metric (9.0/10.0)** - Decades of pioneering Zaratsu polishing and Hi-Beat tech provide a legacy comparable to Omega's Speedmaster milestones.
**Versatility Metric (8.2/10.0)** - Suited for formal and collector occasions with 100m water resistance, it edges out typical dress watches like the Jaeger-LeCoultre Reverso.
**Functions Metric (5.5/10.0)** - Core timekeeping with strong lume and power reserve meets everyday needs like a standard Rolex Oyster Perpetual.
**Complications Metric (4.0/10.0)** - The small seconds subdial adds elegance but falls short of the complexity in a basic IWC Portugieser.
## Total Performance Score (TPS): 4.2
## WM Collector Grade: C
## Performance Insights: Excels in dials, materials, rarity, and movement for collector appeal, but complications and functions lag, delivering solid value above its $12,000 implied price despite the premium retail.
## TPS Interpretation: Modest Value: Superb finishing and exclusivity shine, but simplicity in complications limits bang-for-buck at luxury pricing.
