Evo 9 Spring Drive U.F.A. Ice Forest SLBG003

The ‘Ice Forest’ is the world’s most accurate wristwatch movement powered by a mainspring, representing the brand’s never-ending challenge for innovation.

Its ‘Ultra Fine Accuracy’ Spring Drive calibre classification is the ultimate in Takumi watchmaking, the next step in innovation since the 1969 Grand Seiko VFA, +/-1 second per day ‘Very Finely Adjusted’ classification.

The high-intensity titanium Evolution 9 case design features a new ice forest silvery blue dial design, inspired by the scenery of the Kirigamine Highlands in midwinter, near Shinshu Watch Studio, where all Grand Seiko Spring Drive timepieces are crafted.

At 37mm, the Ice Forest is the most compact 9R automatic Spring Drive model to date and, being crafted from High-intensity titanium, is 30% lighter than stainless steel with high scratch resistance. The silver-coloured hands and indices are Zaratsu polished to a razor edge, with a tempered blue second hand. The Ice Forest is the first Grand Seiko to feature a tool-free micro-adjustable clasp, adjusting in 2mm increments.

The new in-house built 9RB2 Automatic UFA Spring Drive calibre is accurate to +/- 0.3 seconds per day, +/- 20 seconds per year, with a three-day power reserve. The 9RB2 is the first Spring Drive calibre with a mechanism to finely adjust and regulate your own timepiece when required. Designed to resemble the surroundings of Shinshu, its jewels depict the stars sparkling above the mountains, the finishing resembles the frost that winter brings to the forest.

Every Grand Seiko features signature high standards of precision, durability and legibility, handcrafted in Japan by Takumi artisans.
