In celebration of Seiko's 145th anniversary, a special limited edition model tracing Seiko's legacy is now available.

In 2026, Seiko will celebrate its 145th anniversary. Since its founding in 1881, the company has viewed watches as a potential solution to social challenges, consistently pursuing innovation while upholding founder Kintaro Hattori's philosophy to be "always one step ahead of the rest." This new Speedtimer mechanical chronograph features warm gold-colored accents symbolizing success and prosperity.

The new watch also features a dial pattern inspired by the design that was engraved on Kintaro's early timepieces, reinterpreted to include a sporty look that ensures legibility. Set against a white dial, gold-colored accents help to evoke a classic elegance.

Shaped by heritage, this 145th-anniversary watch finds inspiration in the flowing designs and elegantly contoured bracelets of Speedtimer chronographs created in the 1960s and 1970s.
