Grand Seiko has added two new references to its series of watches designed to celebrate Japan’s sekki, a way of dividing the country’s ever-changing seasons into 24 periods through a year.
The Special Edition timepieces in its Heritage Collection are not limited, but will only be available in the United States.
Grand Seiko’s latest additions are said to celebrate sōkō, the end of Fall, when the first frost embraces the forest, with the green color used on the seconds hand and power reserve indicator inspired by an Arashiyama bamboo forest in Kyoto.
Vertical texturing of the dials is also inspired by the forest’s bamboo.
Frost for the 39mm timepieces is expressed in the light silver dial of SBGA427 and the shadow gray dial of SBGA429.
Both use Grand Seiko’s Spring Drive 9R65 Caliber in stainless steel cases with crystal front and back.
They are available with a steel bracelet of crocodile leather strap for $5,000.
