Details

The King Seiko SJE121J1 is a limited edition timepiece celebrating the 145th anniversary of Seiko, marking the brand’s origins as a Tokyo-based clock and watch repair shop founded by Kintaro Hattori in 1881. This special release is part of a small collection that draws on key moments in Seiko's rich history, blending design heritage with modern-day innovations. Featuring elegant gold-coloured accents and a grey Nanako stamped pattern dial, this timepiece beautifully honours Seiko’s origins, while embracing the technical prowess that has made the brand a global leader in watchmaking.

Inspired by Seiko’s King Seiko 45KS from 1969, the SJE121J1 echoes the original silhouette with its curved case, narrow link bracelet, and distinctive 12 o’clock index, shaped like an arrow feather—symbolising Seiko’s forward-thinking vision. The grey Nanako pattern, a signature design used on Seiko’s early pocketwatches, connects this modern watch to Seiko’s founder and the brand's pioneering history in moving from repairs to creation. The watch's sleek box sapphire crystal glass enhances its refined aesthetic, while the slim 9.9mm profile ensures comfortable wear throughout the day.

At the heart of the SJE121J1 is the 6L35 in-house automatic calibre, Seiko’s slimmest movement to date, offering superior accuracy of +15/-10 seconds per day and a 45-hour power reserve. With its bi-directional and semi-instantaneous winding mechanism, this timepiece is both highly practical and exceptionally reliable. Whether you're drawn to its historical significance, its elegant design, or its impressive mechanical performance, the SJE121J1 is a perfect fusion of Seiko’s legacy and its modern, elite watchmaking standards.
