A high-precision hi-beat 36000 with refined design
A beautifully delicate and polished finish has been created on the dial, with a 'Mount Iwate pattern', inspired by the many-ridged contours of the Mt. Iwate, the mountain that is visible through the windows of the Shizuku-Ishi Watch Studio where Grand Seiko mechanical watches are made.

The pursuit of precision
Precision. It's the pursuit of every watchmaker. When Grand Seiko was born in 1960, it was ready to break tradition. After meeting the chronometer standards of the time, Grand Seiko set its own accuracy standards in 1966. By 1998, advancements in materials and craft gave rise to the New Grand Seiko Standard. Every movement undergoes rigorous testing in six positions and three temperatures over seventeen days. The craftsmen and women uphold their commitment to quality while consistently exploring the limits of possibility.
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.
