Spring Drive Chronograph

This Sports style Spring Drive timepiece is within the Evolution 9 Collection, watches created with a contemporary design format based on the recognisable 1967 44GS Grand Seiko Style. This new grammar of design takes the brand’s ideals of beauty, legibility and wearability to new levels with nine design elements.

The Evolution 9 Style of this sports timepiece is based around the three design principles. Firstly an “evolution in aesthetics” – the design expresses infinite gradations between light and shadow achieved with flat Zaratsu polished surfaces combined with hairline finishing.
Secondly an “evolution in legibility” – the powerful hands and grooved, prominent markers with LumiBrite ensure excellent legibility together with the improved Arabic typeface. And thirdly an “evolution in comfort” – curved lugs; the crown guard to reduce damage, and the improved crown shape ensures an easier grip. The case and bracelet are made of high-intensity titanium, providing a lightweight wear with a scratch and corrosion-resistant finish.

This timepiece is powered by the brand’s iconic, exclusive 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. In a Spring Drive watch, the second hand moves in a perfect glide motion, designed to represent the natural continuous flow of time itself. It has a 72-hour power reserve, and a power reserve indicator on the bottom left of the dial.

Spring Drive Calibre 9R86 delivers a precision of ±15 seconds per month, or ±1 second per day and measures elapsed time up to 12 hours to the same level of accuracy. Crucially, it measures time not to the nearest fraction of a second but exactly, thanks to the fact that the glide motion hands stop at the very instant that the button is pressed and not at the nearest ‘tick.’ The GMT function with a bi-directional 24 hour bezel allows the wearer to change the time zones without impairing the movement’s one-second-a-day precision.

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.’
