Astron was created from Seiko’s passion for innovation, and now, under the theme of ‘Solidity,’ a series of solar timepieces have been created for the future of innovation.

Within a super hard coated titanium case, under dual sapphire glass crystal is a dark ‘deep night’ black dial, with a vertical subdial layout – a first for Astron. This model has its own contemporary feel, with its sleek lines, slim profile, and compact, angular design. It has an almost seamless flow from the case, through the lugs and to the bracelet. Its black ceramic bezel that is also protected by a super-hard coating. This piece was designed to have a low centre of gravity, making it fit well on the wrist.

It features a new 5X83 solar-powered movement, that not only charges efficiently, but also features a one twentieth of a second chronograph function for measuring elapsed time. The subdial at 12 o’clock is for the chronograph feature, the subdial at 9 o’clock for setting modes, and the subdial at 6 o’clock for a dual-time feature.

Seiko Astron: the world’s first GPS solar watch – powered by light, automatically adjusted to your exact time through the latest satellite technology.
