King Seiko Automatic 6R 36.1mm SPB459J1

King Seiko was created in the 1960s—a decade famous for fashion in Japan, as well as the rest of the world, and this trio of watches is inspired by the Japanese trends of the Sixties. In Ginza, Tokyo, people gathered on Miyuki Street wearing Oxford shirts, short khaki pants, and penny loafers—a style influenced by the preppy collegiate outfits of the American Ivy League from the 1950s.

Under a box-shaped sapphire crystal lies a green dial, with sharp Dauphine-style hands. The three-dimensional cut indices, angular and sharp case, and finishing ensure maximum light reflection. With an interchangeable bracelet design, this compact 36mm piece allows for greater customization with bracelets and straps.

Powered by the in-house automatic movement 6R51, this watch is precise and features a three-day power reserve.

Long live the new King Seiko: modernized elite watchmaking, yet its regal, dignified, and majestically classic appearance remains.
