Hand-wound spring drive mounted yellow gold model that emits a soft, sparkling light
The pure, understated and subtle design aesthetic of Grand Seiko is evident in every detail, as is the skill and care taken by the watchmakers at the Shinshu Watch Studio where the watch is made. The 18K yellow gold case is polished by a special Zaratsu method created to accentuate the beauty of
the curved surfaces. The dials and the sapphire crystals are also curved to give the watches a classic look.
The dial expresses a unique pattern inspired by the wind-swept snow in the mountains of Shinshu. The new manual-winding Spring Drive caliber, 9R31, has two mainsprings set in parallel within a single barrel, but still captures the signature glide motion seconds hand reflecting the natural and
continuous flow of time, with the same high precision rate of one second a day and delivers a power reserve of 72 hours.
