Grand Seiko STGK021

Features

Elegantly sized and set with diamonds, a new Grand Seiko women’s mechanical watch in stainless steel.

With the new STGK021, elegant proportions and diamond adornment meet the practicality of stainless steel. At just 27.8mm in diameter, this new women’s model is sized for smaller wrists, but it still contains a high-quality Grand Seiko automatic movement, the 9S27.

The dial features a pearl-like shimmering finish, with a molded pattern reminiscent of a beautiful silk cloth. With 45 diamonds set on the bezel, the new STGK021 is sure to sparkle on the wrist as you go about your day.

The exhibition case back is a window into the technical mastery of the watchmakers of the Grand Seiko Studio Shizukuishi, where this elegant women’s watch and other Grand Seiko mechanical timepieces are made.
