SEIKO WATCH AUTOMATIC 'ALPINIST' PROSPEX 39.5MM HBC007J1
Prospex is a combination of the words "Professional" and "Specifications." Seiko Prospex timepieces are designed to be practical, reliable, and durable — built to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. The story begins in 1881, when Kintaro Hattori founded a clock and watch shop in Ginza, Tokyo — the business that would become the Seiko of today. The Alpinist lineage within Prospex dates back to 1959, when Seiko created its first watch specifically for mountaineering — and the Land collection has carried that field-watch heritage forward through every subsequent generation. The HBC007J1 is the most technically complete Alpinist produced to date, adding the new 6R54 GMT calibre to a platform defined by compass functionality and all-terrain capability.
