Description

Lightweight with strong looks, this timepiece has a super hard coated titanium case and a super-clear coated sapphire glass crystal. The black dial features a new highly-textured embossed dial pattern and gold-coloured dial ring. This timepiece features a highly innovative design, with a sharply contoured multi-faceted bezel.

This piece was designed to have a low centre of gravity, making comfortable on the wrist. It comes with a black silicone strap.

Its new in-house 5X63 solar-powered movement not only charges efficiently, but also features a 1/20th of a second chronograph function for measuring elapsed time. The new calibre features a new 24-hour system at 6 o’clock. It is a dual-time chronograph – Seiko’s highest performing GPS Solar movement.

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