Grand Seiko’s SBGY009 is also knowns as the “Asaborake” and is part of the Heritage Collection, housed in a 40mm stainless steel case that is a slim 10.5mm and 46.2mm lug to lug, with a curved sapphire crystal and push down crown providing 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 hand wound Spring Drive 9R31 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, along with a subtle power reserve indicator.

Grand Seiko is known for intricate dials and incredible casework utilizing Zaratsu polishing to create a mirror finish. This white watch dial has a beautiful pattern inspired by Asaborake – the early morning light breaking through the mists of Shinshu, where all Spring Drive watches are made. A heat-blued steel seconds hand adds further visual interest. This Grand Seiko comes on a black crocodile strap and push-button deployant clasp.
