【Product Description】 Created for the modern traveller who demands absolute precision across every time zone, this is the Seiko Astron GPS Solar Ref. 8X53-0AV0-2 — one of Seiko’s most technologically advanced timepieces. The greatest appeal of this model lies in its GPS satellite synchronization system. By receiving signals from GPS satellites, the watch automatically adjusts to the correct local time anywhere in the world with exceptional accuracy, all powered entirely by light through Seiko’s Solar technology. No regular battery replacement and no manual time adjustment are required, making it an ideal companion for frequent travellers and business professionals alike. The 45mm case combines lightweight titanium with scratch-resistant ceramic components, achieving both durability and comfort despite its substantial presence on the wrist. The deep navy dial shifts beautifully between midnight blue and indigo depending on the angle of the light, while the gold-tone hands and baton indexes create a luxurious contrast. Seiko’s LumiBrite luminous coating further enhances visibility in darker environments. The ceramic world-time bezel displays 39 city codes representing major time zones around the globe, including NYC, TYO, LON, and SYD. This functional yet visually striking design gives the watch a distinctly international character that perfectly suits the Astron name. In addition to its advanced GPS technology, this example is offered as a highly complete set including the original Seiko Astron inner and outer box, Japanese instruction manual, guarantee card, and retailer documentation, making it particularly attractive for collectors seeking a genuine and well-preserved example. 【Specifications】 Brand: SEIKO Model: Astron GPS Solar Reference: 8X53-0AV0-2 Movement: GPS Solar Cal.8X53 Functions: GPS satellite synchronization / World time / Date Case Material: Titanium × Ceramic Bezel: Ceramic world-time bezel Dial Color: Navy blue Water Resistance: 10 BAR Serial Number: 872280 Country of Manufacture: Japan Accessories: Original inner & outer box / Japanese handy manual / Guarantee card / Retailer instruction sheets 【Size】 Case Width: 45 mm Case Width: 35 mm 【excluding crown】 Case Length: 43 mm Thickness: 10 mm Lug Width: 18 mm 【Condition】 All functions are currently confirmed to be working properly, including GPS reception and time synchronization.
