{"product_id":"grand-seiko-heritage-collection-sbgw299","title":"Grand Seiko Heritage Collection","description":"\u003cp\u003eAt 36.5mm and hand-wound, this is Grand Seiko at its most classical. Without a rotor the case runs remarkably slim, and the proportions follow the 1960 Grand Seiko First that established the brand's grammar. Every surface is Zaratsu-polished by hand against a rotating tin plate, producing distortion-free mirrors that meet razor-sharp brushed facets along a crisp edge. The hands and indexes are diamond-cut and applied individually.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReference:\u003c\/strong\u003e SBGW299\u003cbr\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Hand-wound, Grand Seiko calibre 9S64\u003cbr\u003e\u003cstrong\u003ePower reserve:\u003c\/strong\u003e approx. 72 hours\u003cbr\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e Stainless steel, 36.5 mm, Zaratsu polished\u003cbr\u003e\u003cstrong\u003eWater resistance:\u003c\/strong\u003e 30 m\u003cbr\u003e\u003cstrong\u003eYear:\u003c\/strong\u003e 2026 — Full set\u003c\/p\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":54641371939182,"sku":"SBGW299","price":4400.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/2479\/8830\/files\/SBGW299.jpg?v=1789403516","url":"https:\/\/luxurygroupstore.com\/ar\/products\/grand-seiko-heritage-collection-sbgw299","provider":"Luxury Group - Rsm.
