The SBGA259 is powered by Spring Drive, Grand Seiko’s unique caliber,
which combines the motive force of a mainspring found with the high
precision of a quartz watch.
The case and bracelet are made with high-intensity titanium, providing a
scratch and corrosion resistant finish, making it 30% lighter than
stainless steel and a pleasure to wear.
The second hand moves smoothly in glide motion, and glows over the
contrasting pure white face to create an even more dramatic movement.
It has a 72-hour (3-day) power reserve, and a power reserve indicator on the bottom left of the dial.
