A Modern Interpretation of a Historic Design
In the 1960s, Grand Seiko pursued the ultimate balance of practicality and beauty, establishing its own distinctive design language.
The culmination of that evolution came in 1967 with the introduction of the 62GS, the brand's first automatic mechanical watch. Its revolutionary bezel-free construction, which secured the crystal directly to the case, together with its sharply faceted case and distortion-free mirror finish, left a lasting impression on the world of watchmaking.
The SBGH351 and SBGH353 reinterpret the iconic design of the 62GS for the modern era.
A design philosophy carefully preserved through generations is brought to life once again through contemporary technology and exceptional craftsmanship, creating timepieces that honor tradition while embracing the future.

SBGH351
Heritage Collection
Inspired by Rikka (Beginning of Summer), one of Japan's 24 traditional solar terms, the SBGH351 captures the refreshing breeze known as Kunpu, which gently sweeps across lush green fields.
Its vivid green dial reveals different expressions as it catches the light, evoking the freshness and vitality of newly emerged foliage.
The case is crafted from Ever-Brilliant Steel, an exclusive stainless-steel alloy offering superior corrosion resistance and a brighter, whiter luster than conventional stainless steel used in luxury watches. The signature 62GS multi-faceted case, finished with distortion-free Zaratsu polishing, creates crisp contrasts of light and shadow from every angle.

SBGH353
Heritage Collection
The SBGH353 draws inspiration from the crystal-clear night sky of the Autumnal Equinox, recalling the serene beauty of a luminous full moon suspended in the evening sky.
Its deep navy-blue dial is accented by a gold-colored seconds hand and the Grand Seiko logo, creating a striking contrast reminiscent of the moon shining brilliantly against a tranquil night sky.
Like the SBGH351, the case is crafted from Ever-Brilliant Steel, prized for both its exceptional corrosion resistance and brilliant white appearance. Precisely faceted hands catch even the faintest light, while the high-beat movement delivers outstanding accuracy and dependable performance for everyday wear.

Mechanical Hi-Beat 36000
Caliber 9S85
Exceptional Precision Resistant to External Disturbances
Operating at a high frequency of 36,000 vibrations per hour (10 beats per second), the Caliber 9S85 minimizes the effects of external disturbances such as changes in position and impact, maintaining outstanding accuracy and remarkably stable performance.
Where Advanced Technology Meets Master Craftsmanship
Ultra-precision components are manufactured using MEMS (Micro Electro Mechanical Systems) technology, adapted from semiconductor manufacturing processes. Each movement is then meticulously assembled and adjusted by the skilled watchmakers at the Grand Seiko Studio Shizukuishi, where every component is fine-tuned to tolerances as precise as one-hundredth of a millimeter.
Approximately 55 Hours of Power Reserve
Although a high-beat movement requires significantly more energy than a conventional mechanical movement, the Caliber 9S85 achieves a practical power reserve of approximately 55 hours when fully wound, thanks to a proprietary high-elasticity mainspring developed in-house.

The Foundation of Grand Seiko Beauty

Ever-Brilliant Steel
A Brilliant White Finish Designed to Last
Ever-Brilliant Steel was developed using a high-performance stainless steel originally engineered for marine environments.
Offering significantly greater corrosion resistance than conventional stainless steels used in luxury watches, it provides exceptional protection against everyday moisture and perspiration.
Its distinctive, brilliantly white luster gives the watch a refined appearance unlike conventional stainless steel. Resistant to rust and designed to retain its beauty for generations, it represents one of the finest materials ever used in Grand Seiko timepieces.
Zaratsu Polishing Functional Beauty Through Distortion-Free Mirror Finishing
A defining element of Grand Seiko aesthetics, Zaratsu polishing is a highly specialized finishing technique performed by master craftsmen.
By carefully pressing each component against a rotating polishing wheel with extraordinary precision, perfectly flat, distortion-free mirror surfaces are created.
These flawlessly finished multi-faceted surfaces produce dramatic contrasts of light and shadow while enhancing the crisp brilliance of Ever-Brilliant Steel, resulting in the unmistakable radiance that defines every Grand Seiko timepiece.

MEMS Technology
Ultra-Precise Components Inspired by Semiconductor Manufacturing
Grand Seiko applies MEMS (Micro Electro Mechanical Systems) technology to manufacture components with precision measured in one-thousandth of a millimeter.
This advanced process creates parts with exceptionally smooth surfaces while significantly reducing weight. The resulting components maintain outstanding durability even under the demanding conditions created by the movement's 10 beats per second operation.
In addition, Grand Seiko's proprietary oil reservoir design improves lubricant retention, overcoming one of the traditional challenges of high-beat mechanical movements and ensuring stable, long-term precision.
