GRAND SEIKO White Birch Spring Drive SLGA009


Shinshu. 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.

The Spring Drive watch carries the latest Caliber 9RA2 which offers a 120 hour power reserve and an enhanced precision rate of ±0.5 seconds per day.

Series 9 Design for the overall look in the case, originally defined in 1967.
Powering the SLGH005 white birch, is the new 9SA5 Hi-Beat caliber with an 80 hour power reserve, dual impulse escapement and a free-spring balance.
