Created as part of a special collection to commemorate 145 years since Seiko began as a Tokyo clock and watch repair shop in 1881, this limited edition model brings together the adventurous heritage of the Alpinist collection with a distinctive anniversary colourway.\u003c\/p\u003e\n\u003cp\u003eThe Alpinist collection was first launched in 1959 and was originally designed for Japanese “Yama-otoko” mountain men, who needed a watch that could be relied upon in challenging terrain. This HBC006 model continues that practical outdoor spirit with a rotating compass bezel and water resistance up to 20 bar, or 200 metres.\u003c\/p\u003e\n\u003cp\u003eThe dial is finished in Edo Murasaki, or Edo Purple, a traditional Japanese colour that symbolises hope for the future and reflects the refined beauty of the Edo period in Tokyo. This rich purple tone gives the watch a strong anniversary identity, while staying true to the characterful styling that makes the Alpinist collection so recognisable.\u003c\/p\u003e\n\u003cp\u003eThe dial features cathedral-style hour and minute hands, classic Arabic numerals and wedge-shaped indices for a distinctive vintage-inspired look. The traditional Alpinist logo sits beneath the Seiko logo, echoing the detail found on the original 1950s Laurel Alpinist. The dial is protected by sapphire glass with an anti-reflective coating on the inner surface, helping to improve clarity and legibility.\u003c\/p\u003e\n\u003cp\u003eThe stainless steel case has a super-hard coating for increased scratch resistance and shine. The case back features a Limited Edition engraving alongside the “Mountain Device” logo, a detail connected to the field-watch nature of the original Alpinist design. The watch is paired with an LWG-approved leather strap, completing its classic explorer-inspired style.\u003c\/p\u003e\n\u003cp\u003eInside the watch is Seiko’s in-house 6R55 automatic calibre, offering a 72-hour power reserve once fully wound. The movement is accurate to -15\/+25 seconds per day, beats at 21,600 vibrations per hour and is equipped with 24 jewels, giving the watch dependable mechanical performance for regular wear.\u003c\/p\u003e\n\u003cp\u003eProspex is a combination of the words “Professional” and “Specifications.” Seiko Prospex timepieces are designed to be practical, reliable and durable, created to meet the demands of sports lovers, adventure seekers and those who appreciate strong technical watchmaking.\u003c\/p\u003e\n\u003cp\u003eAs a limited edition within Seiko’s 145th Anniversary collection, the HBC006 is a special release for collectors and Alpinist enthusiasts. With its Edo Purple dial, 1959 Alpinist heritage, compass bezel and anniversary detailing, this model is expected to be a desirable addition to the Prospex range when it arrives in the UK.\u003c\/p\u003e\n\u003cp\u003eExpected delivery: October 2026\u003c\/p\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":58179563159883,"sku":null,"price":820.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/6336\/5707\/files\/HBC006_soldier.jpg?v=1787138329","url":"https:\/\/avantijewellers.co.uk\/products\/seiko-145th-anniversary-alpinist-automatic-limited-edition-watch-in-edo-purple","provider":"Avanti Jewellery","version":"1.0","type":"link"}
