King Seiko KSK Modern Re-Interpretation. Introduced in 1961 and in production until 1975, King Seiko became one of the company’s most technically innovative and stylish brands, noted for its sleek, dignified angularity. Re-interpreted with a larger, more sporty case and a distinctively bold dial, this limited production model pays tribute to the iconic original with updated styling and technology. Inspired by traditional royal amulets, the dark blue Tamahagane dial evokes an alloy metal used to make swords. As in the original King Seiko, the dial also features meticulously cut three-dimensional indices, including a separately carved 12 o’clock marker, and a date calendar. The new caliber 6R55 24-jewel automatic movement, with a power reserve of approximately 72 hours, beats at a frequency of 21,600 vibrations per hour and provides manual winding capability. Crafted of stainless steel, with the combination of mirror and hairline finishing characteristic of the original King Seiko, as well as the King Seiko crest on the crown and screwdown caseback, this exciting timepiece also offers a box shaped sapphire crystal with anti-reflective coating on the inner surface, and a deployment buckle with push button release clasp. 10 bar, 100M Water Resistant.
