The Spring Drive U.F.A. (ultra fine accuracy) movement from Grand Seiko with an astounding annual rate makes its debut in a limited edition inspired by the beauty of ice forests. The groundbreaking movement 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. Thanks to the movement’s compact design, the new watches have a case diameter of just 37mm, making them the smallest models powered by the 9R series to date and ideal for smaller wrists.

This limited edition watch features a Platinum 950 case and a crocodile strap.

This creation features a blue dial with pressed pattern inspired by the beauty of these ice forests, offering a refined backdrop to the seamless glide motion of a silver-colored seconds hand.
