There are just 2,000 pieces of this limited-edition design available globally, created to mark the 25th anniversary of the 9S Calibre.

The signature textured dial is inspired by the natural phenomenon of clouds surrounding Mount Iwate near the Shizukuishi Watch Studio where Grand Seiko mechanical timepieces are made. We call this scenery the ‘sea of clouds’ or ‘雲海=Unkai’ and it is seen only for a short time when all the weather conditions are right.

‘The Nature of Time’ theme features prominently in Grand Seiko watch designs – a Japanese spirituality where each moment is a unique expression unveiled through light and shadow. The watchmakers’ pride in their surroundings is represented from engineering watch movements which emulate the smooth motion of time passing, to creating dials reflecting the beauty of Japanese nature.
