Styled as a stunning modern reinterpretation of the legendary 1967 44GS design, it features a 40mm stainless steel case that showcases the pinnacle of Grand Seiko's structural geometry. Hand-applied Zaratsu polishing delivers mirror-finished, distortion-free surfaces that contrast sharply with hairline brushed facets, resulting in a compact 46mm lug-to-lug measurement and a 12.5mm case thickness that gives the watch a powerful, architectural wrist presence. On the right side is a screw-down signed crown that sits slightly recessed within the case flank. A wide, smooth bezel with a broad Zaratsu surface holds a flat sapphire crystal, AR-coated on the inside, above a deep and mesmerising midnight blue dial. The dial is engineered to shift dynamically from an almost black ink tone in low light to a brilliant, deep navy blue in direct sunlight. An outer minute track surrounds multi-faceted, diamond-cut trapezoid indices that capture the slightest glimmer of light. Elegant, razor-sharp Dauphine hands are Zaratsu-polished to a mirror finish, complemented by a needle-thin sweeping seconds hand. Between the 7 and 8 o'clock positions, a recessed fan-shaped indicator tracks the power reserve status. At 3 o’clock sits a neatly framed date window, while the applied \"GS\" and printed \"Grand Seiko\" motif anchor the layout at 12 o’clock, balanced by \"Spring Drive\" at 6 o'clock to complete this sophisticated look. The reverse features a screw-down solid or exhibition case back, inside which beats the proprietary Grand Seiko Calibre 9R65 Spring Drive movement. This high-performance, in-house calibre bridges traditional horology and modern physics, generating an electrical charge from a mainspring to activate an ultra-precise quartz oscillator. With 30 jewels, a robust 72-hour power reserve, and a completely friction-free, fluid-sweeping seconds hand, it delivers astonishing accuracy of ±1 second per day. The watch comes paired with its original Grand Seiko 19mm five-link stainless steel bracelet and a signed push-button three-fold clasp with polished and brushed finishing; all links are included. This exquisite piece is sold complete with its original Grand Seiko presentation box, swing tag, and paperwork.\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":57771565711740,"sku":"SBGA375 (9R65-0CV0)","price":3250.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/0771\/3366\/files\/1_008e1d08-1b7f-4959-930b-4ad8b142b96a.jpg?v=1792594397","url":"https:\/\/kibblewatches.co.uk\/products\/2021-grand-seiko-heritage-spring-drive-blue-40mm-sbga375","provider":"KibbleWatches","version":"1.0","type":"link"}
