{"product_id":"grand-seiko-sport-collection-sbgc253","title":"Grand Seiko Sport Collection","description":"\u003cp\u003eThis is the most complicated watch Grand Seiko builds: a Spring Drive chronograph with GMT, where a mainspring provides the power and a quartz oscillator provides the regulation, giving a chronograph hand that glides in perfect continuous motion rather than jumping. Accuracy is quoted at one second per day. The 44.5mm titanium case is Zaratsu-polished by hand, and the movement is developed and assembled entirely in-house.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReference:\u003c\/strong\u003e SBGC253\u003cbr\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Spring Drive chronograph GMT, calibre 9R96\u003cbr\u003e\u003cstrong\u003ePower reserve:\u003c\/strong\u003e approx. 72 hours\u003cbr\u003e\u003cstrong\u003eCase:\u003c\/strong\u003e Titanium, 44.5 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":54641378427246,"sku":"SBGC253","price":9750.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/2479\/8830\/files\/SBGC253.jpg?v=1789403854","url":"https:\/\/luxurygroupstore.com\/es\/products\/grand-seiko-sport-collection-sbgc253","provider":"Luxury Group - Rsm.
