{"product_id":"sbga439g","title":"Grand Seiko Heritage Spring Drive SBGA439G 40.0 mm Steel Midnight Blue Dial Watch for Men","description":"\u003cp\u003eAn archetypal Grand Seiko design with a midnight blue dial. Like a moonlit sky, the colour shifts with the light: at times the warmth of the blue comes forward, at others the dial looks almost black. Against it, the diamond-cut hands and hour markers stand out in sharp relief.\u003c\/p\u003e\n\u003cp\u003ePowered by the Spring Drive calibre 9R65, the seconds hand glides silently and continuously, with no tick. The watch runs for about 72 hours when fully wound, shown on a discreet indicator next to the eight o'clock index. The 40.0 mm stainless steel case has a dual-curved sapphire crystal, a screw case back and a screw-down crown, and is water resistant to 10 bar.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Grand Seiko\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollection:\u003c\/strong\u003e Heritage Collection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e SBGA439G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e Stainless steel, 40.0 mm diameter, 46.6 mm lug-to-lug, 12.3 mm thick\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Dual-curved sapphire crystal with anti-reflective coating on the inner surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e Screw case back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Screw-down crown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater resistance:\u003c\/strong\u003e 10 bar (100 m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Midnight blue with diamond-cut hands and indices\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, seconds, date, power reserve indicator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Grand Seiko Spring Drive calibre 9R65, self-winding with manual winding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower reserve:\u003c\/strong\u003e Approx. 72 hours (3 days)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy:\u003c\/strong\u003e ±15 seconds per month (±1 second per day)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJewels:\u003c\/strong\u003e 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic resistance:\u003c\/strong\u003e 4,800 A\/m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet:\u003c\/strong\u003e Stainless steel, 20 mm band width, 203 mm maximum perimeter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClasp:\u003c\/strong\u003e Folding clasp with push-button release\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 5-year Grand Seiko worldwide warranty (Kamal Watch Co. is an authorised Grand Seiko Mastershop)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":49265059102937,"sku":"SBGA439G","price":450000.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/1221\/4745\/files\/SBGA439G.png?v=1790343743","url":"https:\/\/www.kamalwatch.com\/products\/sbga439g","provider":"Kamal Watch Company","version":"1.0","type":"link"}
