This timepiece is only available from the Grand Seiko website.

At the foot of the great Mount Iwate, Grand Seiko Takumi artisans craft mechanical timepieces in the Grand Seiko Studio Shizukuishi. At the start of each and every day, a bright red sunrise breaks, symbolising a fresh start and a new beginning -this scenery is captured in the design of this piece.

‘Sunrise at Mount Iwate’ is within the Grand Seiko Heritage Collection – timepieces which echo historical styles re-interpreted with the very latest movements, manufacturing techniques and craftsmanship. First released in 1967, the 44GS case shape created a visually recognisable ‘Grand Seiko Style’ design for Grand Seiko watches to follow – balancing legibility and light with a clear and calm dial layout.

Crafted in ‘Ever-brilliant steel’ special alloy which marks a notable leap in the brand’s pursuit of perfection with the world’s highest level of corrosion resistance, giving the steel a special white hue. Under a dual-curve sapphire crystal glass are Dauphine-style silver-coloured hands and indices and this timepiece has an exhibition caseback.

Powered by an in-house 9S85 mechanical hi-beat movement which vibrates 36,000 times an hour, or 10 beats per second, its accuracy is +5 to –3 seconds a day with a power reserve of 55 hours.

Every Grand Seiko features signature high standards of precision, durability and legibility, handcrafted in Japan by Takumi artisans.
