King Seiko 145th Anniversary Limited Edition SJE121

In 2026, Seiko will celebrate its 145th anniversary. The limited edition commemorating this milestone features warm gold accents, symbolizing success and prosperity.
This limited-edition model’s dial draws inspiration from an intricate pattern that Seiko founder Kintaro Hattori arranged to have engraved on imported pocket watches in his company’s early era.
The King Seiko model’s dial combines a finely embossed pattern with a deep gray gradient, creating a sense of depth and refinement while endowing the watch with the capacity to draw the wearer in for closer examination. The motif’s delicate beauty is further enhanced by a gold-colored logo, hands, and indexes, whose radiant contrast exudes elegance and sophistication.
