It proves how Astron and the 5X83 movement represent <strong>a prolific platform<\/strong> to such an extent that it requires all our effort to list the entire lineup. However, we were told that the model reviewed here officially ends the <a href=\"https:\/\/www.seikowatches.com\/us-en\/special\/seikobrand100th\/\" target=\"_blank\" rel=\"noopener\"><strong>100th-anniversary model<\/strong><\/a><strong> line<\/strong>.<\/p>\n<h2 style=\"text-align: justify;\" id=\"the-new-limited-edition-astron-ssh158j1\">The new limited edition Astron SSH158J1<\/h2>\n<p style=\"text-align: justify;\">We <strong>extensively covered the 5X83-powered models<\/strong>, based on the renovated three-counter layout housing the days-of-the-week counter at nine o\u2019clock. To learn more, head to one of our listed Seiko articles.<\/p>\n<p style=\"text-align: justify;\">After <strong>merging with a\u00a0Prospex model<\/strong>, the Astron GPS Solar is an option\u00a0for the collector\u2019s Kintaro Hattori, with the reference <strong>SSH158J1<\/strong>.<\/p>\n<div id='gallery-1' class='gallery galleryid-56502 gallery-columns-3 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.horbiter.com\/wp-content\/uploads\/2024\/10\/seiko-astron-gps-solar-5X83-Edizione-limitata-100-anniversario-7.jpg'><img width=\"150\" height=\"150\" src=\"https:\/\/www.horbiter.com\/wp-content\/uploads\/2024\/10\/seiko-astron-gps-solar-5X83-Edizione-limitata-100-anniversario-7-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"seiko astron gps solar SSH158J1 sette\" loading=\"lazy\" decoding=\"async\" \/><\/a>\n\t\t\t<\/div><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.horbiter.com\/wp-content\/uploads\/2024\/10\/seiko-astron-gps-solar-5X83-Edizione-limitata-100-anniversario-4.jpg'><img width=\"150\" height=\"150\" src=\"https:\/\/www.horbiter.com\/wp-content\/uploads\/2024\/10\/seiko-astron-gps-solar-5X83-Edizione-limitata-100-anniversario-4-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"seiko astron gps solar SSH158J1 quattro\" loading=\"lazy\" decoding=\"async\" \/><\/a>\n\t\t\t<\/div><\/figure>\n\t\t<\/div>\n\n<p style=\"text-align: justify;\">Among the collection\u2019s assets and the reason it undergoes a <strong>relentless product evolution<\/strong> is how quickly the product development\u00a0is compared to any standard mechanical Seiko watch.<\/p>\n<p style=\"text-align: justify;\">In brief, the Astron is a <em>\u201cfast-moving\u201d<\/em> <strong>product<\/strong> from a technological development perspective. In contrast, it is much more affected by obsolescence. However, the refinement is so high that the technological\u00a0leap between one generation and the following is often negligible.<\/p>\n<h3 style=\"text-align: justify;\" id=\"it-is-the-same-yet-different-as-an-ssh156j1\">It is the same (yet different) as an SSH156J1.<\/h3>\n<p style=\"text-align: justify;\">We would have gone for an <strong>SSH158J1 to SSH156J1 head-to-head<\/strong>, but it was a difficult mission given both products\u2019 unavailability.<\/p>\n<p style=\"text-align: justify;\">It would help us and the readers <strong>compare them in detail<\/strong>. An Astron SSH158J1 shares the same architecture as an SSH156J1 and primarily adopts the same combination of materials and treatments with a slightly different gold one.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-53200 aligncenter\" src=\"https:\/\/www.horbiter.com\/wp-content\/uploads\/2025\/03\/seiko-astron-gps-solar-5X83-Edizione-limitata-100-anniversario-6-1.jpg\" alt=\"seiko astron gps solar SSH158J1 sei\" width=\"900\" height=\"600\"><\/p>\n<p style=\"text-align: justify;\">The case and bracelet are <strong>blackened with hardened titanium alloy<\/strong> for the case and outer links. In contrast, polished ceramic is used for the bezel and mid-links.<\/p>\n<p style=\"text-align: justify;\">Rose gold appears on the <strong>crown, pushers, and the ring<\/strong> between the bezel and the case body.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-53211 aligncenter\" src=\"https:\/\/www.horbiter.com\/wp-content\/uploads\/2025\/03\/seiko-astron-gps-solar-5X83-Edizione-limitata-100-anniversario-8.jpg\" alt=\"seiko astron gps solar SSH158J1 otto\" width=\"900\" height=\"600\"><\/p>\n<p style=\"text-align: justify;\">However, we can spot some slight differences compared to a Kintaro Hattori: <strong>the case back is entirely black<\/strong>, and the bezel\u2019s ceramic inlay is smooth compared to an SSH156J1, whose profile is wavy.<\/p>\n<p style=\"text-align: justify;\"><strong>An SSH158J1 is softer overall<\/strong> since rose gold is more subtle than yellow gold. The high-contrast colours on the Kintaro Hattori embody the legendary <strong>black-and-yellow gold combination<\/strong> so popular since the early 1980s on many JDM diving watches and chronographs.<\/p>\n<h3 style=\"text-align: justify;\" id=\"it-is-not-small-but-it-is-light\">It is not small, but it is light.<\/h3>\n<p style=\"text-align: justify;\">At 43.4mm in diameter, 14.1mm in thickness, 49.5 mm lug-to-lug, the Seiko Astron SSH158J1 is a <strong>hefty watch by modern standards<\/strong>, in line with a self-winding mechanical chronograph. Yet, it is perceived size is not since it weighs 124 grams. Thus, it wins hands down in <strong>weight-to-size ratio<\/strong> and comfort once on your wrist.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-53192 aligncenter\" src=\"https:\/\/www.horbiter.com\/wp-content\/uploads\/2025\/03\/seiko-astron-gps-solar-5X83-Edizione-limitata-100-anniversario-2-1.jpg\" alt=\"seiko astron gps solar SSH158J1 due\" width=\"900\" height=\"600\"><\/p>\n<p style=\"text-align: justify;\">The watch <strong>exudes luxury from any angle<\/strong>, setting it apart from an ordinary satellite watch. Kudos to Seiko\u2019s designers for playfully highlighting\u00a0the matte to polished finish.<\/p>\n<p style=\"text-align: justify;\">The Seiko Astron SSH158J1 100<sup>th<\/sup> Anniversary Seiko Brand Limited Edition combines state-of-the-art satellite technology <strong>with a premium feel<\/strong>, thus addressing a specific audience.<\/p>\n<h2 style=\"text-align: justify;\" id=\"final-thoughts\">Final thoughts<\/h2>\n<p style=\"text-align: justify;\">The Seiko Astron GPS Solar SSH158 Seiko Brand 100<sup>th<\/sup> Anniversary Limited Edition debuted as <strong>a 1200-piece limited edition model<\/strong>. It retails for 3,200 euros, making it a direct competitor to an SSH156J1.<\/p>\n<p style=\"text-align: justify;\">If you desire a more elaborate touch, <strong>a commemorative box<\/strong>, or an <strong>additional rubber strap<\/strong> (a relevant option on a 100-meter waterproof satellite watch), head to a Kintaro Hattori. The reference SSH156J1 is geared towards\u00a0<strong>a more European-based audience<\/strong> whose appreciation for rose gold outperforms anything else in the benchmark.<\/p>\n<div id='gallery-2'
