{"product_id":"grand-seiko-sport-sbgn029-18400382","title":"Quartz GMT Sport","description":"\u003cp\u003eThis sports timepiece demonstrates the essential qualities of Grand Seiko: accuracy, beauty, legibility, durability and ease of use. The case is a classic slim design for a comfortable fit, its surface features a finely brushed hairline finish – a skill perfected by Grand Seiko crafts people – contrasting the signature Zaratsu mirrored polishing. This watch is powered by the in-house 9F86 Quartz caliber adjusted to an accuracy of -\/+ 10 seconds per year. 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. Caliber 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. The 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. Grand Seiko: beautifully precise Japanese watchmaking, handcrafted by Takumi artisans.\u003c\/p\u003e","brand":"Grand Seiko","offers":[{"title":"Default Title","offer_id":48259796730101,"sku":null,"price":3700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/9458\/0469\/files\/18400382_1.jpg?v=1781323749","url":"https:\/\/larevv.com\/de\/products\/grand-seiko-sport-sbgn029-18400382","provider":"Larevv","version":"1.0","type":"link"}
