{"product_id":"grand-seiko-spring-drive-u-f-a-slgb001","title":"Grand Seiko Spring Drive U.F.A. SLGB001","description":"\u003cp\u003eThe intricately textured dial of the SLGB001 captures the serene beauty of the frost-covered trees that define the Kirigamine Highlands in winter. Its deep, lustrous blue surface reflects the subtle interplay of light and shadow, evoking the crisp stillness of a frozen landscape.\u003c\/p\u003e\n\u003cp\u003eThe Evolution 9 (E9) design follows Grand Seiko’s signature aesthetic, with its broad, faceted hands; prominent grooved markers; and precise combination of Zaratsu-polished and hairline-finished surfaces. Measuring 37mm in diameter, the case’s compact proportions ensure a comfortable and elegant fit on the wrist. The SLGB001 is presented on a crocodile strap, secured with a Platinum 950 three-fold clasp featuring elements of 18k white gold.\u003c\/p\u003e\n\u003cp\u003eThe SLGB001 is powered by the revolutionary Spring Drive Caliber 9RB2, a movement that sets a new standard in precision. With an extraordinary annual accuracy of ±20 seconds, it earns the Ultra Fine Accuracy (U.F.A.) designation, making it the most precise mainspring-powered movement ever created. This achievement is made possible through an advanced quartz oscillator, a newly developed integrated circuit, and a vacuum-sealed regulation system that shields the movement from environmental factors. The 72-hour power reserve and 34-jewel construction ensure long-term performance and reliability. Through the exhibition case back, the movement’s fine detailing and mirror-polished bevels reflect the masterful craftsmanship of the Shinshu Watch Studio, where Grand Seiko Spring Drive timepieces are made.\u003c\/p\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":50442991960147,"sku":"SLGB001","price":39000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/8249\/8131\/files\/SLGB001-grand-seiko-watch-spring-ufa-ice-forest-platinum.png?v=1790117075","url":"https:\/\/kenjo.net\/products\/grand-seiko-spring-drive-u-f-a-slgb001","provider":"Kenjo","version":"1.0","type":"link"}
