We are pleased to announce that the Grand Seiko Flagship Boutique New York at 540 Madison Avenue has reopened its doors with a dedicated pop-up space.
The SBGH353 honors Shūbun, the autumnal equinox in Japan’s ancient calendar, with a deep blue dial that reflects the serene beauty of clear night skies illuminated by the moon and stars. Gold accents add a luminous touch, evoking the season’s tranquil charm.
Inspired by the iconic 62GS from 1967, this modern reinterpretation retains its bezel-free design, Zaratsu-polished surfaces, and sharp edges, delivering a sleek and refined aesthetic. Crafted from Ever-Brilliant Steel, the case and bracelet offer exceptional durability and a radiant finish.
Powered by the Hi-Beat Caliber 9S85, this timepiece achieves remarkable precision with a frequency of 36,000 vibrations per hour and a 55-hour power reserve. A dual-curved sapphire crystal and exhibition case back complete the design, combining elegance with advanced craftsmanship.
The case design reflects Grand Seiko’s rich heritage, taking inspiration from the legendary 62GS—the brand’s first automatic watch, unveiled in 1967. Renowned for its bold mirrored surfaces, multi-faceted case, and innovative bezel-free construction that emphasizes the dial, this contemporary reinterpretation faithfully preserves the pioneering spirit of the original.
The deep blue dial evokes the tranquil beauty of clear autumn nights during Shūbun. Its rich color contrasts with the gold-toned Grand Seiko logo and seconds hand, mirroring the luminous glow of the moon and stars against the dark sky.
The case and bracelet are crafted from
Ever-Brilliant Steel, a highly corrosion-resistant alloy with a PREN value 1.7 times higher than most high-end watch steels.
A high-frequency mechanical movement hand-assembled by the artisans of the Grand Seiko Studio Shizukuishi. Engineered for precision, it achieves an impressive accuracy of +5 to -3 seconds per day (when static) and offers a power reserve of approximately 55 hours.
