In 1969, the 45KS launched and was entered into international watchmaking competitions for accuracy. It became Seiko’s, and Japan’s, first ever certified ‘Chronometre,’ as an exceptionally accurate mechanical timepiece. Inspired by this landmark in Seiko history, King Seiko introduce the ‘Forest Green’ re-interpretation of the 4502-8020 original.
The redux echoes the original silhouette with its curved case shape, date feature and 12 o’clock index cut like an arrow feather. It features a narrow link bracelet in true Seiko Sixties style of the time.
This timepiece is crafted to be only 9.9mm in depth, being powered by Seiko’s slimmest automatic in-house calibre. With a bidirectional and semi-instantaneous winding mechanism, this 6L35 timepiece is highly practical, and accurate to +15/-10 seconds per day, with a 45-hour power reserve.
Long live the new King Seiko: modernised elite watchmaking, yet its stately, dignified and majestically classic looks remain.
