Inspired by the Hotaka mountains. Crafted in their shadow.
This Spring Drive classic is made by the craftsmen and women of the Shinshu Watch Studio in Japan’s Nagano Prefecture. The studio is surrounded by the Hotaka mountains that, for several months each year, are covered in snow. In the crisp, dry air, and when driven across the slopes by the wind, this snow has a special light and delicate quality that is captured in the subtly textured surface of the dial. The blue tempered steel seconds hand moves over it in the perfect glide motion that is Spring Drive’s unique signature and reflects the continuous, eternal and beautiful nature of time.
A Spring Drive model with a high-intensity titanium case that achieves a true lightweight feel
The SBGA211 is powered by Spring Drive, Grand Seiko’s unique calibre, which combines the motive force of a mainspring found with the high precision of a quartz watch.
The case and bracelet are made with high-intensity titanium, providing a scratch and corrosion resistant finish, making it 30% lighter than stainless steel and a pleasure to wear.
The blue steel second hand moves smoothly in glide motion, and glows over the contrasting pure white face to create an even more dramatic movement.
It has a 72-hour (3-day) power reserve, and a power reserve indicator on the bottom left of the dial.

The special whiteness of driven snow
This Spring Drive watch is made and assembled by hand at the Shinshu Watch Studio high in the mountains of Nagano Prefecture in Central Japan. When snow falls, as it does every winter, it forms into light, hard crystals that sparkle in the sun and, driven by the cold wind, create delicate patterns as they drift on the sharp dry air. This effect is captured on the dial whose brilliant whiteness holds a secret. It is not painted white but is made by a special silver plating process that allows the creation of the delicate texture of the snow to be replicated so perfectly. White magic.
The art of Zaratsu polishing and high intensity titanium
The Zaratsu polishing of steel is an art that takes many years to master. To use this technique on a material that is harder than steel is an even greater challenge but is one that Grand Seiko succeeded in meeting with this watch case. It has the elegant combination of hairline and mirror finishes and the sharply defined edges that are central to the Grand Seiko Style and the mirror finishes are free of all distortion. The result is a watch whose many interlocking surfaces act as a perfect stage for the interplay of light and shadow.
The three movements at the heart of Grand Seiko
One of the world's foremost mechanical movements, the culmination of high-precision micro-engineering and the attention to detail of Seiko's expert watchmakers.
Spring Drive is a unique movement that delivers one-second-a-day precision, using just the power of a mainspring.
