Larger case with Grand Seiko’s heritage design, powered by a quartz movement
This model is equipped with an ultimate quartz movement, integrating all the essential qualities of Grand Seiko’s wristwatch into its functionality and design.
Based on Grand Seiko’s signature standard design, this model has a larger case size of 40 mm to complete a low-profile watch with an imposing and engaging presence.
As we enlarged the case and the dial, we also adopted longer hands and indexes with more sophisticated chamfering, which has resulted in improved visibility.
The blue-green dial highlights the user’s active personality.

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.
