From the King Seiko Collection. 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. Designed for sophistication and comfort, this elegant timepiece features a slim 10.7mm case, as well as sharply delineated case and crystal edges. The 26-jewel 6L35 caliber movement, with a frequency of 28,800 vibrations per hour, a power reserve of approximately 45 hours, and manual winding capability, offers such features as a bi-directional winding system and rapid date change mechanism within its slender profile. In a new cool black color with a blue tint, the dial features diamond cut hands, meticulously cut dimensional indices with a separately carved 12 o’clock marker, and a date calendar. Crafted of stainless steel, with super-hard coating and the combination of mirror and hairline finishing characteristic of the original King Seiko, as well as the King Seiko crest on caseback and crown, this elegant timepiece also offers a box shaped sapphire crystal with anti-reflective coating on the inner surface and a deployment clasp with push button release. 5 bar, 50M Water Resistant
