Grand Seiko’s SBGA413 is part of Grand Seiko’s Heritage “Seasons” Collection and is sometimes referred to as “Shunbun” or “Spring”, for the spring equinox. It is housed in a 40mm titanium case that is 47mm lug to lug, with a box shaped sapphire crystal and screw down crown that provide 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 visible behind a sapphire case back.

Grand Seiko is known for incredible casework (with Zaratsu polishing) and dials. The case shape is less commonly seen, and its design is based on the celebrated 62GS from 1967, providing a robust wrist presence but comfortable lug to lug distance. The pale pink textured dial transports you to “Hana-Ikada”, meaning floral raft, when clusters of cherry blossoms scattered by the wind cover a river’s surface. The magic of this treasured moment in the Japanese calendar hints at the pleasure one gains from a profound understanding of the nature of time. A GS logo in gold adds further visual interest and provides a hint of how special this watch is. This Grand Seiko comes on a five-link satin finished titanium bracelet with a folding clasp and two half links to finely adjust the fit.
