King Seiko KSK Modern Re-Interpretation. Inspired by the elegant dress/sport King Seiko of the 1960s, this distinctive watch re-interprets one of Seiko’s most technically innovative brands, noted for its sleek, dignified angularity. A newly developed slim case and the thin 6R31 automatic movement, with a frequency of 21,600 vibrations per hour, a power reserve of approximately 70 hours, and manual winding capability, make this re-interpretation exceptionally slender and elegant, with a case thickness of only 10.33 mm. The dark charcoal sunray dial features meticulously cut three-dimensional indices, including a separately carved 12 o’clock marker, while the box shaped crystal offers anti-reflective coating on the inner surface. Crafted of stainless steel, with the combination of mirror and hairline finishing characteristic of the original King Seiko, and the King Seiko crest on caseback and crown. Includes a tri-fold push button release clasp. 10 bar, 100M Water Resistant.
