In addition to the Giugiaro Design Limited Edition, Seiko presents six new Astron GPS Solar chronographs.
Introduced in 2014, the Astron GPS Solar Chronograph is an evolution of the world’s first GPS Solar watch. In 2015, six new references join the collection. The first two models (SSE023J1 and SSE025J1) feature super-hard coated titanium cases with crocodile leather straps.

The next three Astron GPS Solar chronograph references (SSE027J1, SSE029J1 and SSE031J1) are in super-hard stainless steel with bracelets that feature ceramic inserts.

Among the steel variants, SSE027J1 (SBXB027*) features a white dial with matching ceramic bezel. It comes with super-hard stainless steel bracelet featuring white ceramic centre links.
