{"product_id":"seiko-5-sports-field-gmt-hdb002k-mens-automatic-watch","title":"Seiko 5 Sports Field Series GMT 39.4mm HDB002K","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Seiko 5 Sports Field Series GMT HDB002K takes the most useful complication in travel watchmaking and drops it into a case that disappears on the wrist. The stainless steel case measures 39.4mm across, 13.6mm thick and just 47.9mm lug to lug — compact, honest field-watch proportions with drilled lugs and a 20mm strap width. A fixed steel bezel engraved with a 24-hour scale rings a warm ivory dial, where high-contrast Arabic numerals carry both 12- and 24-hour markings and a bold orange-red GMT hand cuts across the whole thing as a single point of focus.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eLumiBrite-coated hands and markers hold their charge for genuine low-light legibility, a date sits at three o'clock, and a curved Hardlex crystal gives the dial a subtle vintage bow. The five-link stainless steel bracelet closes on a one-push three-fold clasp with a double-lock, and the automatic movement is visible through a see-through screw-down caseback.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eInside is Seiko's in-house Calibre 4R34, an automatic GMT movement with manual winding and hacking seconds, running at 21,600 vibrations per hour with a power reserve of approximately 41 hours. This is the point worth understanding: Seiko has designed and built its own movements since 1881, and the 4R34 is a genuine caller-style GMT — a mechanical dual-time complication in a watch positioned at the entry point of the automatic market, where GMTs almost never appear.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe HDB002K is water resistant to 100 metres and magnetically resistant, so it handles swimming, rain and daily wear without a thought. It's a men's automatic GMT watch built for someone who actually travels — a small, tough, dual-time steel watch that works with a suit, a t-shirt or a boarding pass.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWhat we love about this watch:\u003c\/strong\u003e The HDB002K solves a problem most watch brands ignore — that a proper mechanical GMT usually means either a big wrist or a big budget. At 39.4mm and 47.9mm lug to lug with an in-house automatic GMT calibre and 100m water resistance, this one asks for neither. The ivory dial is the quiet star of it, warm enough to read as neo-vintage against the orange-red GMT hand without ever looking like a costume. This is Seiko doing what Seiko does better than anyone: engineering that punches far above its price and then refusing to make a fuss about it.\u003c\/p\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":46270866096314,"sku":"HDB002K","price":675.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/3781\/5994\/files\/hdb002k.png?v=1785829766","url":"https:\/\/starbuy.com.au\/products\/seiko-5-sports-field-gmt-hdb002k-mens-automatic-watch","provider":"Starbuy Australia","version":"1.0","type":"link"}
