Grand Seiko’s SBGA415 is part of the Heritage “Seasons” Collection and is referred to as “Winter”. The Taisetsu is housed in a 40mm titanium case that is 47mm lug to lug, with a curved sapphire crystal and screw down crown that provides 100m of water resistance. This watch case, while having the comfort and low weight of titanium, is polished using the Grand Seiko Zaratsu technique and has a sheen that will deceive the eye into thinking it is stainless steel. Inside it has 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. The case shape is less commonly seen, and its design is based on the celebrated 62GS from 1967, providing a robust wrist presence and a comfortable lug to lug length. The light gray textured “Winter” dial is inspired by the deep winter snows that cover the mountains in Taisetsu, the twenty-first of Japan’s twenty-four seasons. A heat-blued steel seconds hand and “Spring Drive” in blue adds further visual interest. This Grand Seiko comes on a five-link satin finished titanium bracelet with a three-fold clasp and two half links to finely adjust the fit.
