This Seiko Astron GPS watch features Calibre 3X – the very latest Astron GPS Solar movement. In size, in energy efficiency and in signal reception, it demonstrates how far Seiko’s technology has come since the introduction of the first GPS Astron Solar watch. The case is less than 40mm in diameter thanks to the reduced GPP reception antenna that uses components distributed across a single plate. The watch maintains the same high level of reception performance and offering a power reserve of approximately six months.

Seiko Astron: the world’s first GPS solar watch which never needs a battery change – powered by light, automatically adjusted to your time zone through the latest GPS technology.
