Seiko Astron Solar System – GPS Solar Silvertone 'Earth' Limited Edition

This Astron solar-powered timepiece is themed 'Solidity,' symbolising Seiko's innovative spirit, present since the brand’s beginnings in 1881. Within a series taking inspiration from the solar system, this piece is inspired specifically by Earth.

Limited to only 1,500 pieces worldwide, in a new futuristic design, this solar watch features a two-piece aluminium and super-hard coated titanium bezel. Crafted in a super-hard titanium case with sapphire crystal glass, the distinctive silver-coloured striped pattern dial is particularly difficult to create on a solar cell, without reducing its charge efficiency. This model has a contemporary feel, with sleek lines, slim profile, and compact, angular design it has an almost seamless flow from the case, through the lugs and to the bracelet. The micro-adjustable clasp feature adds a more personalised fit.

The watch is powered by an in-house built 3X62 Solar-powered movement with GPS functionality for exceptional accuracy - being updated remotely by GPS satellite when the wearer moves between time zones. It can be charged by any light source - either natural sunlight or artificial light - for convenience.

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