Grand Seiko’s SBGY007 is also known as the “Omiwatari” and is part of the Elegance Collection, housed in a 38.5mm stainless steel case that is a slim 10.2mm and 43.7mm lug to lug, with a curved sapphire crystal and push down crown providing 100m of water resistance. 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 watch case required an adaptation of the Zaratsu polishing technique for curved surfaces so its sloping lugs could achieve an immaculate, distortion-free shine. This ice blue watch dial has a beautiful pattern inspired by Omiwatari or “pathways of the gods”. These pathways are formed in the cold of winter, as the surface of Nagano’s Lake Suwa freezes over, and long ridges appear in the ice that reach from shore to shore. A heat-blued steel seconds hand adds further visual interest. This Grand Seiko comes on a crocodile strap and push-button deployant clasp.
