Grand Seiko SBGA031
The Spring Drive-powered SBGA031 combines the robustness that Seiko has famously enhanced since creating Japan's first diver watch in 1965 with the simple aesthetics that it has refined with the Grand Seiko line since 1960.

The result is a comfortable 137-gram Grand Seiko timepiece that is delightfully practical, delivering uncompromising reliability in what many regard as the world's best line of high-end watches.
