{"product_id":"seiko-prospex-divers-watch","title":"Prospex 1968 Heritage GMT Diver's Watch Oceanic Black","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSixty years of deep-sea expertise, distilled into a single watch. The Seiko Prospex HBC002J1 is a modern re-interpretation of Japan's iconic 1968 hi-beat diver's watch — the timepiece that defined a generation of professional diving. Now reimagined in commanding Oceanic Black, it introduces something entirely new to the Prospex family: mechanical GMT.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003ePowered by the in-house Calibre 6R54, the HBC002J1 becomes the first Seiko diver's watch to feature a mechanical GMT movement, allowing you to track a second time zone with the ease of a rotating 24-hour hand. With an automatic movement, 72-hour power reserve and 24 jewels, this is precision engineering built not just for the ocean, but for life at pace across time zones.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe case, 42mm in diameter and 13.3mm thin , is crafted from polished and brushed stainless steel, topped with a scratch-resistant Japanese ceramic diving bezel and protected by anti-reflective sapphire crystal. At 300 metres of water resistance, reinforced by a screw-down crown and screw case back, this watch is genuinely built for the depths.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eOn the wrist, the experience is equally considered. The stainless steel bracelet is engineered with a low centre of gravity and short-pitch links, sitting flush and comfortable even during active wear. The three-fold clasp with micro-adjustment allows a precise, personalised fit, down to the millimetre. LumiBrite on hands, indexes and bezel ensures legibility in total darkness, at depth or above.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe black dial is bold without being brash: clean indices, a sweeping seconds hand and the confident stop-seconds function complete a watch that transitions effortlessly from boardroom to boat.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHeritage note\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eProspex has been Seiko's commitment to the serious adventurer since 1965. The 1968 model was a watershed moment: Japan's first hi-beat one-piece diver's watch, setting a benchmark that still resonates.\u003c\/p\u003e","brand":"SEIKO","offers":[{"title":"Default Title","offer_id":57126150701431,"sku":"HBC002J1","price":1600.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0402\/0643\/4455\/files\/SEIKOProspexGMTDiverOceanicBlack.png?v=1779933129","url":"https:\/\/www.deacons-jewellers.com\/products\/seiko-prospex-divers-watch","provider":"Deacon \u0026 Son  ","version":"1.0","type":"link"}
