Long-awaited and cherished forever: Grand Seiko's first Spring Drive watch
After 28 years of development it was finally happening: Grand Seiko introduced the innovative Spring Drive calibre. To be admired in full glory for the first time in this model! SBGA203 has an innovative movement that combines the drive of a mechanical watch with the unrivalled accuracy of a quartz movement. All this goes hand in hand with 72 hours of power reserve and an accuracy of 1 second per day. The calibre is visible through the transparent backbox, but the design itself is so beautiful that you keep looking!
