{"product_id":"grand-seiko-heritage-collection-sbgp009","title":"Grand Seiko Heritage Collection","description":"\u003cp\u003eGrand Seiko's 9F quartz is not the quartz anyone else makes. Regulated to within ten seconds a year, it uses a twin-pulse motor strong enough to drive heavy hands, a backlash auto-adjust mechanism that stops the seconds hand jittering, and a sealed cabin keeping dust from the movement for fifty months between battery changes. The case is Zaratsu-polished by hand and the indexes are diamond-cut and applied individually.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReference:\u003c\/strong\u003e SBGP009\u003cbr\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Grand Seiko 9F quartz, ±10 seconds per year\u003cbr\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e Steel, 40 mm\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":54641382719854,"sku":"SBGP009","price":2340.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/2479\/8830\/files\/SBGP009.jpg?v=1789403579","url":"https:\/\/luxurygroupstore.com\/es\/products\/grand-seiko-heritage-collection-sbgp009","provider":"Luxury Group - Rsm.
