Grand Seiko STGK023

Features

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

With the new STGK023, elegant proportions and diamond adornment meet the practicality of stainless steel. At just 27.8mm in diameter, this new ladies’ model is sized for smaller wrists, but it still contains a high-quality Grand Seiko automatic movement, the 9S27.

The dial is mizu hanada, a pale blue indigo and features a molded pattern reminiscent of a beautiful silk cloth. Eleven diamonds on the dial serve as hour markers, ensuring that the new STGK023 has a brilliant sparkle 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 ladies’ watch and other Grand Seiko mechanical timepieces are made.
