Remarks The King Seiko 56 series is often regarded as one of the best value propositions in the vintage watch market, offering finishing and mechanics that rivaled Swiss luxury counterparts of the 1970s. This specific reference, with its clean dial and sharp case architecture, is a perfect entry point for collectors looking to experience high-grade Japanese watchmaking. History Introduced in the late 1960s and produced through the mid-1970s, the 56KS line was manufactured by the Suwa Seikosha factory. It was designed to offer high-beat precision in a thinner, more wearable automatic package. The King Seiko line holds a special place in history as the internal rival to Grand Seiko, pushing the brand to achieve new heights in accuracy and design excellence during the quartz crisis era. / Second Vintage SKU: SEI-SKH-0010
