Inspired by the beauty of white birch forests
SLGH005 captures the dynamism of the white birch tree forests near the studio in Shizukuishi, where all Grand Seiko mechanical 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 high-beat watch is powered by the revolutionary Caliber 9SA5, which offers a power reserve of 80 hours thanks to its enhanced energy efficiency.

The design is true to the Grand Seiko Style defined back in 1967 with the celebrated 44GS, but its heritage is combined with a powerful contemporary feel that points towards a new era.
Case back
The bridge has a gently curving outline that is inspired by the shape of Mt. Iwate and a bend in the nearby Shizukuishi River that runs past the studio where the watch is made.
Movement
The high-beat watch is powered by the revolutionary Caliber 9SA5, which offers a power reserve of 80 hours thanks to its enhanced energy efficiency. First presented in 2020, Caliber 9SA5 incorporates three significant developments, the entirely new Dual Impulse Escapement, the Grand Seiko free-sprung balance, and the horizontal gear train which, together, set a new standard in high-beat horology.
