Spring Drive Seasons: Winter "Taisetsu" SBGA415

This timepiece is from the Japanese Seasons collection – designs inspired by the twenty four ‘Sekki’ or seasons in Japan; since ancient times these changes in the weather and nature have been incorporated into Japanese daily life.

The dial of this watch is inspired by the deep snow of winter when the world has settled into a slumber only to awaken in the spring. This model’s grey dial with a boulder pattern celebrates the winter snow as it gathers and glitters against the sunlight.

‘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.

This timepiece is powered by the brand’s iconic Spring Drive movement, one of the most significant developments in recent watchmaking which took 28 years to develop.
With a superior level of precision, Spring Drive generates energy with a mainspring combined with an electronic regulator, never requiring a battery change.
Seiko Watch Corporation pioneered Spring Drive which is only available in their timepieces.

Every Grand Seiko features signature high standards of precision, durability and legibility, handcrafted in Japan by Takumi artisans.
Grand Seiko: beautifully, precise Japanese watchmaking, from the pinnacle of Seiko Watch Corporation’s in-house ‘manufacture.’
