A Spring Drive GMT that shines in 18k Yellow Gold and Blue
The contrast between the 18k yellow gold of the bezel and the blue of the indicator ring is a new color scheme within the sport collection and a first for Grand Seiko. Inspired by the morning sun floating on the horizon, beneath the sapphire crystal bezel lies a bold expression of blue, delivering
a strong sense of transparency, breadth and depth. This timepiece achieves the difficult balance of high performance and elegance.
Equipped with a GMT hand, this watch features Grand Seiko’s unique Spring Drive caliber, which combines the motive force of a mainspring with the high precision of a quartz watch. The second hand movement over the blue dial, further highlights a glide motion that reflects the natural and continuous flow of time itself.
