Evolution 9 Spring Drive UFA

From the retailer listing

An icy dawn, stunning Spring Drive accuracy This new Grand Seiko Spring Drive U.F.A. creation is based on the “Evolution 9 Style,” a unique design grammar that takes the fusion of Grand Seiko’s spirit with the aesthetic sensibilities of Japan to a higher level. Its textured, violet-colored dial expresses the breathtaking moment when dawn breaks over the frost-covered forests of the Shinshu region of central Japan, where all Grand Seiko Spring Drive watches are meticulously crafted. Receiving the new U.F.A. designation, standing for “Ultra Fine Accuracy,” the Spring Drive Caliber 9RB2 powering this watch boasts a level of precision defined not by accuracy in seconds per day, week, or month, but by its accuracy over one year. The automatic U.F.A. movement has an astounding annual rate of ±20 seconds, making it the most accurate wristwatch movement powered by a mainspring today.
