Description

This timepiece is limited to only 1,500 pieces worldwide.

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

Lightweight with strong looks, within a super hard coated titanium case, under dual curve sapphire glass crystal is a navy blue dial with rose gold coloured accents. It showcases a vertical subdial layout and horizontal line pattern. 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, with a polygonal bezel design.

This piece was designed to have a low centre of gravity, making comfortable on the wrist. The five-piece bracelet is crafted from a combination of titanium and ceramic for lightweight wearing. It has a micro-adjustable clasp feature. The caseback has a three-dimensional globe symbol.

It features a new in-house 5X83 solar-powered movement, that not only charges efficiently, but also features a 1/20th 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.
