{"product_id":"grand-seiko-heritage-collection-sbgh349","title":"Grand Seiko Heritage Collection","description":"\u003cp\u003eThe Hi-Beat calibre inside this Grand Seiko oscillates at 36,000 vibrations per hour — ten beats a second — buying resistance to positional error and a smoother sweep than a conventional movement delivers.

The 40mm steel case is Zaratsu-polished by hand, with diamond-cut indexes applied individually.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReference:\u003c\/strong\u003e SBGH349\u003cbr\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Automatic Hi-Beat 36000, calibre 9S85\u003cbr\u003e\u003cstrong\u003ePower reserve:\u003c\/strong\u003e approx. 55 hours\u003cbr\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e Stainless steel, 40 mm, Zaratsu polished\u003cbr\u003e\u003cstrong\u003eWater resistance:\u003c\/strong\u003e 100 m\u003cbr\u003e\u003cstrong\u003eYear:\u003c\/strong\u003e 2026 — Full set\u003c\/p\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":54641421779310,"sku":"SBGH349","price":5660.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/2479\/8830\/files\/SBGH349.jpg?v=1789403591","url":"https:\/\/luxurygroupstore.com\/da\/products\/grand-seiko-heritage-collection-sbgh349","provider":"Luxury Group - Rsm.
