Seiko - Since its creation just two years ago, the Presage Sharp Edged Series has quickly established a place in the world of fine watches for its combination of traditional mechanical watchmaking with a distinctively modern Japanese style. With a combination of polished and hairline brushed edges, the stainless-steel case has been meticulously crafted for a lustrous finish and feel and is treated with super hard coating for longevity. This open heart textured blue dial is paired with a brown leather strap. This stunning mens watch is powered by the movements of the wearer or by winding the crown and has approximately 45hrs power reserve at full charge. The SPB311J features a patterned, open heart dial and encased in sapphire crystal glass. The case size is 40.2mm and has a see through case back. Made in Japan.
