HBC009J","description":"\u003cp\u003eSeiko introduced the Alpinist in 1961 with a clear purpose: to create a dependable tool watch for Japan's mountain climbers and outdoor explorers. It marked a pivotal moment for the brand—Seiko's first true foray into sports watches—drawing inspiration from the Yama-Otoko, the \"mountain men\" who relied on tough, trustworthy gear to navigate rugged terrain and unpredictable conditions.\u003cbr\u003e\u003cbr\u003eDecades later, the Alpinist story evolved once again. In the mid 2000s, Seiko revived the spirit of the original with a modern reinterpretation that quickly became a fan favorite. What made the Alpinist so beloved was not just its aesthetics, but its versatility, effortlessly fitting into both business settings and weekend adventures. Eventually, production wound down, leading many collectors to wonder whether Seiko had quietly retired one of its most purposeful everyday sports watches. Just as speculation grew, Seiko delivered an unexpected twist, the return of the Alpinist, reimagined under the Prospex line and refreshed with a modern GMT movement and upgraded features.\u003c\/p\u003e\n\u003ctable style=\"width: 500px;\" cellspacing=\"1\" cellpadding=\"1\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0213\/7833\/4784\/files\/SeikoHBC008J-04.jpg?v=1792565790\" alt=\"\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e\u003cspan style=\"color: #696969;\"\u003e\u003cem\u003eSeiko Prospex Alpinist GMT Black Ref.

The popularity of the SARB series was due to the diversity and uniqueness of the watch. It could be worn in any situation, whether business or casual. Continuing that journey, the Alpinist GMT lineup today welcomes a strong new member featuring a glossy black dial while retaining the iconic case shape. Its one of a kind case design has hit a home run with watch enthusiasts for almost a decade and a half, right as collector demand was reaching a peak.\u003cbr\u003e\u003cbr\u003eThe Alpinist keeps its familiar 39.5mm diameter, with a 46.4mm lug to lug length and a 20mm lug width. Now slimmed down to just over 12.7mm, it wears even sleeker on the wrist. The stainless steel case continues the classic Alpinist design language and is enhanced with Seiko's Diamond Shield coating to resist minor scratches. At the 3 o'clock position, a screw down crown with protective crown guards reinforces its tool watch roots, while the exhibition case back features a mountain range motif that ties beautifully to the Alpinist heritage. With 200m of water resistance, it remains a capable and dependable companion for any adventure.\u003c\/p\u003e\n\u003ctable style=\"width: 500px;\" cellspacing=\"1\" cellpadding=\"1\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0213\/7833\/4784\/files\/SeikoHBC008J-02.jpg?v=1792565790\" alt=\"\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e\u003cspan style=\"color: #696969;\"\u003e\u003cem\u003eOriginal Alpinist hour markers and hands set\u003cbr\u003e\u003c\/em\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eLook closer, and the Alpinist now boasts a durable sapphire crystal with inner anti reflective coating, paired with a magnifying Cyclops for enhanced legibility. The main focus is the refined glossy black dial background. This glossy surface provides a high contrast backdrop for the hour markers, creating an ultra-clean display that feels sophisticated and effortless to read at a glance.\u003cbr\u003e\u003cbr\u003eThe \"Alpinist\" name now sits proudly at 12 o'clock, paired with the Prospex \"X\" emblem at 6 o'clock to mark its evolution within the modern lineup. The watch preserves all the signature elements that define the Alpinist identity — the iconic cathedral hands, the applied hour markers, and the familiar dial layout enthusiasts have loved for decades. Broadening its functional capability, a dedicated GMT hand displays a prominent arrow tip outlined in red for quick time zone tracking. Each element is treated with Lumibrite for reliable low-light visibility, keeping the spirit of the original firmly intact.\u003c\/p\u003e\n\u003ctable style=\"width: 500px;\" cellspacing=\"1\" cellpadding=\"1\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0213\/7833\/4784\/files\/SeikoHBC008J-06.jpg?v=1792565790\" alt=\"\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e\u003cem\u003e\u003cspan style=\"color: #696969;\"\u003eBeautiful case with internal rotating bezel \u003c\/span\u003e\u003c\/em\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThe main traits of what this the \"Japanese Explorer\" has to be its internal rotating bezel, which doubles up as a compass for the mountain climbers which the watch was intended for and is operated by rotating the second crown at 4 o'clock. Complementing this mountaineering heritage, the fixed outer steel bezel displays a crisp 24 hour numerical scale. This dual bezel arrangement transforms the classic field watch into a highly practical dual time instrument capable of tracking multiple time zones with effortless clarity.\u003cbr\u003e\u003cbr\u003eThe old Alpinist SARB017 used the 6R15 automatic movement during its launch. Well, since the 6R15 produced in 2005, the Seiko Sumo range adopted this movement since day one, and have relied on it until 14 years later, where Seiko decided that they should refresh the collection with the latest engine- the 6R54. This movement is totally new in 2023, making this timepiece the first few to feature Seiko's new automatic caliber with a GMT function. Maintaining operation at 21,600 BPH (3 Hertz) with hacking and hand winding capabilities, this engine has 24 jewels and a longer power reserve of 72 hours (3 days), a whopping 22 hours more than the 7R and 6S.\u003c\/p\u003e\n\u003ctable style=\"width: 500px;\" cellspacing=\"1\" cellpadding=\"1\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0213\/7833\/4784\/files\/SeikoHBC008J-08.jpg?v=1792565790\" alt=\"\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003e\u003cspan style=\"color: #696969;\"\u003e\u003cem\u003eSeiko luminous glows brightly in the dark\u003c\/em\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThe timepiece is equipped with a 20mm black leather strap featuring unified tone on tone stitching.
