Grand Seiko Sport Collection
Inheriting the royal design of Grand Seiko diving watches, this timepiece is powered by the Caliber 9S85 high-frequency mechanical movement.
The second hand ticks smoothly on the black dial, which does not reflect light.
The bezel has a design that can be disassembled during after-sales service, and the unique feature of Grand Seiko is that fine dust that has fallen on the dial can be carefully removed.
Outer material -  titanium which is lighter than stainless steel, less prone to rust and less prone to scratches
