Every quartz crystal has different performance characteristics, but only the most accurate are picked for Grand Seiko 9F movements. Grown in-house, aged and rigorously tested over a 3 month period, this ensures only the best quartz oscillators are crafted into each timepiece. \u003cbr\u003e\u003cbr\u003eCalibre 9F delivers long-lasting high performance through innovation: the instant Date Change Mechanism swiftly changes the date display; the torque is comparable to a mechanical movement allowing easy-to-read wider and longer hands; the Second hand precision achieves positional accuracy on the dial against the markers; and the sealed structure means high retention of lubricating oils.  \u003cbr\u003e\u003cbr\u003eThe screw-lock crown means the watch maintains excellent airtightness with a 20 bar water-resistance, as well as durability. Its powerful hands and grooved, prominent markers with LumiBrite ensure high legibility, whilst the contrast created by the upper and lower two-toned dial rings indicates if the GMT hand time is day or night.\u003cbr\u003e\u003cbr\u003eGrand Seiko: beautifully precise Japanese watchmaking, handcrafted by Takumi artisans.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":52590399291658,"sku":"SBGN027G","price":3300.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/5276\/5450\/files\/grand-seiko-mens-sport-slate-39mm-quartz-gmt-watch-p41915-67517_image.jpg?v=1781648782","url":"https:\/\/www.francisandgaye.co.uk\/products\/grand-seiko-mens-sport-slate-39mm-quartz-gmt-watch-sbgn027g","provider":"Francis \u0026 Gaye","version":"1.0","type":"link"}
