Grand Seiko Heritage Spring Drive – SBGA375

Grand Seiko’s SBGA375 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 has a midnight blue dial, as close to black as possible, giving it great versatility and balance. 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.
