Description

This watch is one of a series of ‘Iwao’ pattern dials, with a rock-like texture inspired by nature. The Katsu-iro dial colour of this timepiece is inspired by the distinctive armour worn by Japanese Samurai warriors during the Sengoku period – dyed indigo – “Katsu-iro” – which represented their bravery.

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.’
