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 platinum 950 Evolution 9 case design features a new ice forest pattern 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.

The silver-coloured hands and indices are Zaratsu polished to a razor edge, whilst the accompanying crocodile leather strap’s clasp is crafted from Platinum 950 and 18 carat white gold. At 37mm, the Ice Forest is the most compact 9R automatic Spring Drive model to date.

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.

This timepiece is limited to only 80 pieces worldwide and in the UK is exclusively available from London’s New Bond Street Grand Seiko boutique.

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