Seiko King Seiko Collection Automatic Watch With Manual Winding, Stainless Steel Bracelet Strap, 37mm Case & Black Coloured Dial. King Seiko is a mechanical watch brand that beautifully designed and finished mechanical watches with high accuracy. Renewed, enhanced and as striking as ever. The 1960’s was a decade of unprecedented advances for Seiko, both in terms of technical development and design creativity. Alongside Grand Seiko, one other series demonstrated the company's ability to create beautifully designed and finished mechanical watches with high accuracy. It was called King Seiko. In addition to its precision, it offered a powerful yet graceful design that symbolized the high quality of its construction. Today, after more than half a century, the King Seiko collection is back with timepieces that showcase the lasting quality of Seiko’s mechanical watchmaking. The lasting design values of 1965. The technology and engineering of today. The 1965 KSK, the design that defined King Seiko. The five new watches share a distinctively sharp and angular design that is inspired by the 1965 King Seiko KSK, which was the second series to be created and the one that defined the character of King Seiko. The combination of a flat dial with faceted indexes and broad, razor-edged hands gives the watch a refined and striking presence. Case The case is constructed so that, combined with the boxed-shaped sapphire crystal, it gives each watch a slim and elegant feel. An anti-reflective coating on the inner surface of the crystal delivers high legibility from any angle. Index & Hands The bold, faceted lugs have sharp angles and wide flat surfaces that feature both mirror and hairline finishing, creating a sense of precision. The twelve o’clock index is more than twice the width of the others and has a patterned texture specially crafted to ensure high legibility and to give the dial a bright sparkle that invites the eye. New King Seiko emblem The crown and case back bear the new King Seiko emblem whose design was inspired by that of the 1965 KSK.
