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 Series 9 Design 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 centre of gravity that ensures that the watch sits easily and securely on the wrist.
The high-beat watch is powered by the revolutionary Calibre 9SA5, which offers a power reserve of 80 hours thanks to its enhanced energy efficiency.
After the wide acclaim given over many years to the Calibre 9S series of mechanical movements, it had long been Grand Seiko’s goal to push the boundaries back further and create a new mechanical movement with enhanced performance, just as the first 9S movement had done two decades before. The decision was taken to aim for a new 10-beat movement that would offer a greatly increased power reserve. This is how Calibre 9SA5 was born.
Calibre 9SA5 is the direct result of the synergy of these two important assets, as its advanced functionality and its exquisite craftsmanship bear powerful testament.
