To commemorate the 60th anniversary of the birth of Grand Seiko, a representative Japanese wristwatch, Seiko will release its first stainless steel model equipped with the innovative mechanical caliber 9SA5, which was released in 2020, in limited quantities from Friday, December 11th.

Automatic movement (Cal. 9SA5). 47 jewels. 36,000 vph. Power reserve approximately 80 hours. Stainless steel case (diameter 40mm, thickness 11.7mm). Water resistant to 10 bar. Price: 1 million yen (excluding tax). Limited to 1000 pieces worldwide.

 While based on the "Seiko Style" design grammar inherited by Grand Seiko, the design of the original Grand Seiko, which is the origin of it all, has been reexamined to enhance visibility and wearability, adopting a universal design that will lead the Grand Seiko of a new era. This is the first stainless steel model equipped with the 9SA5 movement, and the low-center-of-gravity case design and wider links than conventional metal bands provide excellent wearability.

The high-beat movement (9S8 series) installed in previous Grand Seiko models, which vibrates at 36,000 vibrations per hour, has a running time of approximately 55 hours when fully wound. However, the Caliber 9SA5 uses a highly efficient escapement and twin barrels (two power springs), which allows it to run for a significantly longer time, approximately 80 hours when fully wound, despite its high-beat of 36,000 vibrations per hour.

Grand Seiko was born in 1960, bringing together the best of the technology and craftsmanship of the time. Since then, the brand has built its legacy by striving to create the finest watches, pursuing and realizing the essential qualities of a watch—accuracy, legibility, and beauty—at a high level through tireless progress, and this year marks its 60th anniversary. This model is equipped with the caliber 9SA5 of the "Mechanical Hi-Beat 36000 80 Hours," making it a model that embodies 60 years of tradition and innovation.
