Grand Seiko Spring Drive Titanium

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.
