Model SBGA285 offers a classic interpretation of the Grand Seiko Style. Its 39mm case perfectly showcases Grand Seiko's mastery of finishing, boasting a beautiful blend of Zaratsu polished and hairline surfaces. The black dial features multi-faceted hands and hour indexes. SBGA285 is powered by Spring Drive, Grand Seiko’s proprietary caliber that combines the motive force of a mainspring with the high precision of a quartz watch. Emblematic of Spring Drive, the second hand glides around the dial, reflecting the continuous flow of time itself. The dial features a power reserve indicator by 8 o’clock, which tracks the power reserve (72 hours) of the movement.
