Inspired by the beauty of white birch forests from new Evolution 9
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.
