Seiko 145th Anniversary Limited Edition of 2,000 pieces

Seiko commemorates 145 years with a limited-edition Astron model powered by the new GPS Solar Dual-Time Chronograph Caliber 5X63.
In the second series of commemorative limited-edition watches celebrating Seiko’s 145th anniversary, a blue accent inspired by “Seiko Blue” is used. Established in the 1960s and refined over time, Seiko Blue continues to embody the Seiko brand identity.

Thanks to the new movement, the sub-dials are arranged across the dial in a symmetrical layout.
This limited edition celebrates the anniversary with striking blue accents inspired by Seiko Blue, a signature color that reflects Seiko’s pioneering spirit.

The blue seconds track and sub-dials stand out against the light silver hue of the main dial, resulting in a refreshingly modern and refined look.
The limited-edition creation includes an exclusive silicone strap featuring a blue-and-white color combination.

The case features a quick-change system, which enables easy removal of straps and bracelets with the push of a button. Add a new strap simply by pressing it in place for a secure fit. This enables an instant switch between the titanium bracelet and an exclusive silicone strap for a versatile look and enhanced functionality.
