Seiko Astron Mens Sports GPS Solar
This Seiko Astron GPS watch features Calibre 3X – the very latest Astron GPS Solar movement made in Japan. The case is less than 40mm in diameter thanks to the reduced GPS 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. 10 bar water resistant with sapphire crystal glass.
