Grand Seiko’s SBGH273 is part of the Heritage Collection, and part of a collection celebrating the Japanese aesthetic of 24 Seasons. It is housed in a 40mm stainless steel case that is 47mm lug to lug and 12.9mm thick, with a curved sapphire crystal and screw down crown that provides 100m of water resistance. This watch is powered by Grand Seiko’s Automatic Caliber 9S85, providing 55 hours of power reserve. This caliber is a high beat movement, beating at 10 beats per second (or 36,000 per hour) with precision of +5 / -3 seconds per day, and 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 watch is referred to as the “Shūbun” (the Autumnal Equiox) as its uniquely textured shimmering dial is inspired by a clouds floating across a dark moonlit autumn sky. A gold seconds hand and GS logo, with text showcasing the high beat movement further highlight the blue dial. 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.
