The pursuit of high accuracy has been the cornerstone of Grand Seiko’s values since its first watch was created in 1960. In the late 1970s, the development of Spring Drive began with an aim to harmoniously blend the traditional energy of a mainspring with state-of-the-art electronic watchmaking advancements. In 2004, Grand Seiko introduced the Spring Drive Caliber 9R65 with a monthly rate of ±15 seconds.
Today, this legacy of accuracy in watchmaking reaches new heights with the announcement of the Spring Drive Caliber 9RB2, which receives the new U.F.A. designation, standing for “Ultra Fine Accuracy.” 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.*
*As of April 2025, based on Grand Seiko’s research.
In 2025, the Caliber 9RB2 makes its debut in the Evolution 9 Collection. To the east of the Shinshu Watch Studio lie the Kirigamine Highlands, where frost-covered trees can be observed during harsh winter months. The intricately textured dial captures the beauty of these ice forests thanks to finishing techniques that create pale blue tones that are subtle yet striking in their presence.
