King Seiko watch movements

Japanese name: キングセイコー

King Seiko is a historic sub-brand within the Seiko watch family, introduced in 1961 as a counterpart to the Grand Seiko line in the pursuit of watchmaking excellence. With an emphasis on precision, durability, and style, King Seiko watches were designed to showcase the best of Japanese horology during the 1960s and 1970s. The brand became known for its refined aesthetics, high-quality mechanical movements, and distinctive case designs, which set it apart from its contemporaries. Although production of the original line of King Seiko models ceased in the late 1970s, the brand retains a loyal following among vintage watch enthusiasts and collectors who appreciate its unique blend of history, craftsmanship, and design.
