Released as a highly significant milestone in the brand's heritage timeline, it was produced as a limited edition to commemorate the 25th anniversary of the legendary 9F quartz calibre, which famously marked the first time a GMT function was integrated into this pinnacle quartz movement platform. This distinctive timepiece features a 40mm stainless steel case with a curvaceous, sinuous profile that utilises Grand Seiko’s legendary hand-applied Zaratsu polishing for distortion-free mirror surfaces. The faceted case architecture features a smooth conical bezel and integrated fluid case lines, offering a versatile lug-to-lug length of 46.5mm and a sophisticated thickness of 12mm for a powerful, balanced presence on the wrist. A signed screw-lock crown. The standout feature of this model is its multi-level, deep forest green dial adorned with a stamped, repeating \"GS9F\" geometric monogram pattern that incorporates the historic original quartz symbol. The architectural layout features 24-hour numerals, applied polished and brushed faceted indices, and an exclusive gold 5-pointed star at 6 o'clock symbolising its enhanced high-precision regulation. Razor-sharp, polished faceted dauphine hands alongside a striking yellow arrow GMT hand are engineered for intuitive tracking. Protecting this complex design is a dual-curved sapphire crystal featuring a multi-layer interior anti-reflective coating. On the reverse, a solid screw-down caseback is beautifully decorated with the iconic Grand Seiko 18ct yellow-gold lion medallion and a custom 25th-anniversary engraving. Inside beats the proprietary Japanese-made thermocompensated Calibre Grand Seiko 9F86. This customised high-performance movement features hand-selected quartz crystals regulated to an astonishing accuracy of ±5 seconds per year, a twin-pulse control motor driving heavy hands, an anti-backlash mechanism for a precise, shudder-free tick, and an independent hour-hand adjustment for seamless global travel without stopping the watch. The watch comes paired with a 20mm bespoke three-link stainless steel bracelet that tapers into a branded twin-trigger deployant clasp.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb id=\"docs-internal-guid-cb276d81-7fff-3b34-2752-92f717d696f5\"\u003e\u003c\/b\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":56816278897020,"sku":"SBGN007 (9F86-0AC0)","price":2950.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/0771\/3366\/files\/1_d78b47a8-6c59-4e67-b58d-4bf9bf4d27b0.jpg?v=1779974338","url":"https:\/\/kibblewatches.co.uk\/products\/2018-grand-seiko-9f-gmt-25th-anniversary-green-40mm-sbgn007","provider":"KibbleWatches","version":"1.0","type":"link"}
