Seiko - Astron - 7X52-0AV0 - Men - 2010-2020

1. Introduction
We are pleased to present a historic first-generation SEIKO ASTRON GPS Solar, powered by the milestone Caliber 7X52 movement that pioneered satellite-linked atomic timekeeping globally. Based on the serial number "413109" on the case back, this high-tech modern classic was manufactured in Japan in January 2014, representing the legendary early era of accessible Japanese smart-luxury watchmaking.

This timepiece beautifully showcases the bold architectural design of the early 7X series, defined by a dramatic, high-domed box sapphire crystal that emphasizes its unique dimensional form. The solid, polished stainless steel case is masterfully paired with a glossy black ceramic city-code bezel and a deep charcoal-black dial accented by sharp, raised silver-tone indices. Combining executive class with a sporty layout, this exceptional silver-and-black monochrome flagship model commands an incredible, timeless presence on the wrist.
