{"product_id":"grand-seiko-evolution-9-collection-slgc001g-tentagraph","title":"Grand Seiko Evolution 9 Collection","description":"\u003cp\u003eThe Tentagraph is the first mechanical chronograph Grand Seiko has ever built, and the name states the achievement: ten beats per second, 36,000 vibrations per hour, sustained across a three-day power reserve. Running a chronograph at that frequency without sacrificing autonomy is genuinely difficult, and the movement uses a dual-impulse escapement developed in-house to manage it. The titanium case is Zaratsu-polished by hand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReference:\u003c\/strong\u003e SLGC001G (Tentagraph)\u003cbr\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Automatic Hi-Beat chronograph, in-house calibre 9SC5\u003cbr\u003e\u003cstrong\u003ePower reserve:\u003c\/strong\u003e approx. 72 hours\u003cbr\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e Titanium, 43.2 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":54641439342958,"sku":"SLGC001G","price":10770.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/2479\/8830\/files\/SLGC001GTENTAGRAPH.jpg?v=1789404004","url":"https:\/\/luxurygroupstore.com\/ar\/products\/grand-seiko-evolution-9-collection-slgc001g-tentagraph","provider":"Luxury Group - Rsm.
