Grand Seiko Spring Drive U.F.A. – Ultra-Fine Accuracy in Platinum and Titanium
The Grand Seiko Spring Drive U.F.A. represents the pinnacle of Japanese watchmaking precision and aesthetic sophistication. Inspired by the frozen forests of Shinshu, this watch captures the essence of winter with its silvery blue and deep blue dials, featuring intricate textures that subtly and elegantly reflect light.
Evolution 9 Style Design
With a 37 mm diameter, the 950 platinum and High-Intensity Titanium cases combine ergonomics, comfort, and refined aesthetics. The Zaratsu mirror-polished finish alternates between polished and brushed surfaces, while the straps—crocodile for platinum and titanium with micro-adjustment—ensure a secure and balanced fit on the wrist. Prominent indices and textured hands provide maximum legibility, following the design language of the Evolution 9 collection.
Revolutionary Precision with Spring Drive U.F.A.
At the heart of this watch is the 9RB2 Spring Drive U.F.A. caliber, a high-precision automatic movement accurate to ±20 seconds per year. Vacuum-sealed and with programmed thermocompensation, it ensures stability against humidity, static electricity, and temperature changes. It also includes a regulation switch to maintain precision even after extended use.
Visible Movement and Finishing
Through the sapphire caseback, one can admire the decoration inspired by Shinshu frost, with jewels evoking winter stars and textured surfaces reflecting snow on trees. The iconic continuously sweeping seconds hand symbolizes the fluidity of time.
