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 GPS Solar Dual-Time Chronograph celebrates Astron's spirit of innovation. Symbolizing success and prosperity, gold-coloured accents grace every part of the watch, from the dial and bracelet to the case.
The bezel features a gold-coloured sapphire crystal insert that adds depth and dimension. Even the gold-coloured markings at 1, 4, and 5 on the UTC scale offer a subtle tribute to the 145th anniversary.
