Spring Drive White Birch

Shirakaba. The white birch tree that thrives in Shinshu

SLGA009 captures the quiet mood of the white birch tree forests near the studio in Shinshu, where all Grand Seiko Spring Drive watches are crafted. To look closely at the dial is to experience the exact same feeling that the visitor to these forests receives and to be brought closer than ever to the true and eternal nature of time.

The overall look of the watch is known as the Evolution 9 Style and it will be an important part of the Grand Seiko’s signature in the years to come. Its powerful hands and grooved, prominent markers ensure perfect legibility, its Zaratsu polished, distortion-free mirror finish and delicate hairline finish alternate give the case a quiet and harmonious glow. The case has wide lugs and a low center of gravity that ensures that the watch sits easily and securely on the wrist.

This Spring Drive watch carries Grand Seiko's latest Caliber 9RA2 which offers a 120 hour power reserve and an enhanced precision rate of ±0.5 seconds per day.
