The latest Seiko Astron GPS Solar Dual-Time Chronograph features a new quick-change system for easy strap and bracelet replacement. The new Caliber 5X63 combines Dual-Time technology with a chronograph function that measures up to 24-hours during chronograph operation at increments of 1/20th of a second.

Case
The new creation inherits Astron’s signature dynamic case design, characterized by its multi-faceted, dimensional profile. The brushed finishing on the top surface of the faceted bezel contrasts elegantly with the polished sides, enhancing the structure’s presence.

Dial
The sub-dials are arranged horizontally across the dial in a symmetrical layout. Set against the main dial’s geometric pattern of interlocking triangles, the display conveys a sense of poised stability.

Bezel
Featuring a newly introduced two-piece titanium octagonal bezel, achieving a low center of gravity and enhancing the wearing comfort of the lightweight titanium case.

Bracelet
It features a quick-change system, which enables easy removal of bracelet with the push of a button; adding a new strap is as simple as pressing it in place for a secure fit. This enables an instant switch between the titanium bracelet and an exclusive option strap for a versatile look and enhanced functionality.
