While its architecture is immediately recognizable as a modern Alpinist, the Glacier Blue dial completely changes its character. Its heavily textured surface interacts brilliantly with light, with both the color and apparent depth of the dial changing depending on viewing angle.\u003c\/p\u003e\n\u003cp\u003eMore importantly for collectors, this was not a broadly distributed Prospex release. The SPB339J1 was produced specifically for the Chinese market in a run of just 500 pieces, making it substantially scarcer than most modern Alpinist limited editions. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"JDM Horologist","offers":[{"title":"Default Title","offer_id":50981768298739,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/4984\/1907\/files\/image_2026-09-06_155212123.png?v=1788684661","url":"https:\/\/jdmhorologist.net\/products\/seiko-dragon-alpinist-spb339j1-limited-edition-500","provider":"JDM Horologist","version":"1.0","type":"link"}
