Unleashing the Artistry of the Katana, Grand Seiko introduces U.S. Exclusive Models influenced by the materials and craft of the blade.
A Limited Edition of 500 for reference SBGA493, inspired by the forge uses a unique dial pattern within the series. While still inspired by the katana, the SBGA493 expresses the determination and fiery spirit needed to craft the blade. The deep red color with yellow gold-tone accents is influenced by the heated blade during the forging process. The pattern emulates the radiating sparks created when the hammer strikes the blade.
All three models are made of stainless steel and measure 40mm in diameter, 12.5mm in thickness, and 46.2mm in length. Each features a stainless steel bracelet with a three-fold clasp, a dual curve sapphire crystal, and an exhibition case back revealing the Spring Drive Automatic Caliber 9R65. Caliber 9R65 has a power reserve of 72 hours, 30 jewels, and an accuracy of ±1 second per day (±15 seconds per month).
Models SBGA489 and SBGA491 will be available for $5,600 starting this August, and SBGA493 will be available beginning this September for $6,000. All three models will be available exclusively at Grand Seiko Boutiques, the Grand Seiko Boutique Online, and select Grand Seiko Authorized Retailers operated in the US.
