Seiko King Seiko SPB371 Blue Dial 39mm Automatic

Between 1961 and 1975, King Seiko represented the pinnacle of Japanese watchmaking, competing internally with Grand Seiko to achieve technical perfection.

The SPB371 revives this distinguished legacy with a 39mm case that honors the original's architectural angularity while introducing modern proportions. The Tamahagane-inspired blue dial features a lattice pattern echoing the silk finishes of 1960s King Seiko models, with each three-dimensional index individually crafted and the 12 o'clock marker separately carved for exceptional definition.

Inside, the new Caliber 6R55 automatic movement delivers 72 hours of power reserve while maintaining the traditional 21,600 vibrations per hour beat rate. The case showcases the signature combination of mirror and hairline finishing that defined the original King Seiko aesthetic, enhanced by wider lugs with brushed tops and polished facets. A box-shaped sapphire crystal with anti-reflective coating and the historic King Seiko crest on both crown and caseback complete this sophisticated tribute.
