Features
A new tough design
A sturdy bezel, a bold vertical streak, and a form that asserts toughness while being light in style.
It is a model that incorporates a new Grand Seiko case structure following the Grammar of Design Philosophy created for a tough and rugged lifestyle. The Lumi Brite hands and markers shine in the dark with perfect harmony, which expands the user's action range. The ballistic nylon strap adopts the
lightweight and sturdy cordura fabric, a first for Grand Seiko.
At the heart, high precision caliber 9F delivers higher performance and greater durability, keeping reliable time even under harsh environments.
