SLGB003","description":"\u003cp\u003eThe Grand Seiko SLGB003G “Ice-Forest” is a groundbreaking timepiece that combines serene aesthetics with the pinnacle of Spring Drive technology. Its delicately textured silver-blue dial evokes the frost-covered forests of the Kirigamine Highlands near the Shinshu Watch Studio, while the tempered blue seconds hand glides smoothly in silent precision. Housed in a 37 mm high-intensity titanium case—the smallest ever to contain a 9R-series movement—it offers lightweight comfort at just 100 g, with a durable three-fold clasp featuring tool-free micro-adjustment for a custom fit.\u003c\/p\u003e\n\u003cp\u003eAt its core is the new Spring Drive 9RB2 U.F.A. (Ultra Fine Accuracy) caliber, delivering ±20 seconds per year precision—the most accurate mainspring-driven watch in the world as of 2025. This movement features aged quartz oscillators, a low-power IC with environmental compensation, a vacuum-sealed sensor for stability, and a regulation switch for post-purchase fine-tuning, all while maintaining a 72-hour power reserve. Finished with a box-shaped sapphire crystal, screw-down crown, sapphire case-back, and mirror-polished surfaces that echo the frost motif, the SLGB003G is both a technological milestone and a refined tribute to Japanese nature and craftsmanship.\u003c\/p\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":43089110630461,"sku":"SLGB003","price":16300.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/0022\/6365\/files\/Grand-Seiko-Evolution-9-Spring-Drive-U.F.A.-SLGB003.jpg?v=1775547141","url":"https:\/\/houseofkennedy.com\/products\/grand-seiko-evolution-9-spring-drive-u-f-a-slgb003","provider":"House of Kennedy","version":"1.0","type":"link"}
