Grand Seiko’s SBGA471 is a US exclusive Special Edition known as the “Soko Frost”. The Soko Frost is part of the Heritage Collection, housed in a 40mm stainless steel case that is 46.2mm lug to lug, with a curved sapphire crystal and screw down crown that provides 100m of water resistance. This watch case, known as the 44GS, is based on Seiko’s grammar of design, focused on flat, geometrically perfect surfaces polished to best reflect light. The Spring Drive 9R65 Caliber (assembled and adjusted by hand at the Shinshu Watch Studio) provides a smooth sweeping seconds hand with an astonishing precision of +/- 15 seconds per month, unprecedented for a watch powered by a mainspring. The beautiful movement provides 72 hours of power reserve, is anti-magnetic, and is visible behind a sapphire case back.

Grand Seiko is known for intricate dials and incredible casework utilizing Zaratsu polishing to create a mirror finish. This watch celebrates sokō – the end of autumn where the first frost embraces the forest, with a vertically textured light blue dial inspired by the frozen trunks of the bamboo trees lining the Arashiyama forest. This Grand Seiko comes on a five-link polished and satin finished bracelet with a three-fold clasp and two half links to finely adjust the fit.
