Grand Seiko's new SBGA523 launches as limited-edition Spring Drive watch with peacock feather dial
Grand Seiko's new SBGA523 is a limited-edition Spring Drive watch created exclusively for Japanese department store chain Daimaru. Set to release in early October 2026, the watch is limited to just 200 pieces distributed across five Daimaru locations — Shinsaibashi, Kyoto, Kobe, Tokyo, and Sapporo — and carries a retail price of ¥825,000 including tax (approximately $5,700).
The dial is what seals the deal in this collaboration. Its translucent mint-green color is overlaid with a diagonal feather pattern drawn from Daimaru's corporate symbol, the peacock. The sweeping, upward-rising lines are a reference to growth and aspiration, and the see-through quality of the teal finish gives the dial a depth that shifts with light and viewing angle.
The case is based on Grand Seiko's classic 44GS design lineage. It features the brand's signature Zaratsu-polished flat surfaces that create sharp, mirror-like transitions between facets. It measures 46.2 x 40.0 mm with a thickness of 12.5 mm and is built in stainless steel. The caseback carries an individual "1 of 200" engraving alongside a display back for movement viewing.
Inside sits the 9R Spring Drive caliber — Grand Seiko's proprietary movement that uses a mainspring for power while relying on an integrated circuit and quartz oscillator to regulate timekeeping. The result is a rated accuracy of ±15 seconds per month, or roughly ±1 second per day, which is exceptional for a mechanically-driven watch. Power reserve stands at 72 hours, or about three days on a full wind.
The SBGA523 is a Japan-only release with no broader availability indicated yet.
