Its dark dial is accented by applied Roman numerals and baton markers, blued screws, sculpted hands, and an open section at 6 o’clock that reveals the intricate double-tourbillon mechanism.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe dial displays central hours and minutes, small seconds at 9 o’clock, and a sector-style power-reserve indicator at 3 o’clock. The patented Double Tourbillon 30° construction places a one-minute inner tourbillon inclined at 30 degrees inside an outer cage that completes one rotation every four minutes. This continually changes the position of the regulating organ to help average gravitational effects across different wearing positions.\u003c\/p\u003e\n\u003cp\u003eThe watch is powered by the manually wound Greubel Forsey Caliber GF02, a 39-jewel mechanical movement operating at 21,600 vibrations per hour. Two series-coupled mainspring barrels provide an approximate 72-hour power reserve. Visible through the sapphire exhibition caseback, the movement showcases extensive hand finishing, including polished bevels, gold chatons, blued screws, and the distinctive warm-toned treatment of the bridges and mainplate.\u003c\/p\u003e\n\u003cp\u003eA sapphire crystal protects the dial, while the sapphire caseback provides a clear view of the movement and double-tourbillon architecture. The white-gold case is completed by sculpted lugs, an engraved case-band design, and a prominent crown bearing the Greubel Forsey emblem. The watch is fitted with a black Greubel Forsey leather strap and a signed white-gold pin buckle.\u003c\/p\u003e\n\u003cp\u003eCondition: Preowned\u003cbr\u003eScope of delivery: watch comes with box and with a 2-year service guarantee.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eKey Details\u003c\/p\u003e\n\u003cp\u003eBrand: Greubel Forsey\u003c\/p\u003e\n\u003cp\u003eModel: Double Tourbillon 30° Vision\u003c\/p\u003e\n\u003cp\u003eCollection: Double Tourbillon 30°\u003c\/p\u003e\n\u003cp\u003eReference: \u003cspan class=\"rQesXe MPyX\"\u003eGF02\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eMovement: Manual winding, Greubel Forsey Caliber GF02\u003c\/p\u003e\n\u003cp\u003eJewels: 39\u003c\/p\u003e\n\u003cp\u003eFrequency: 21,600 vibrations per hour\u003c\/p\u003e\n\u003cp\u003ePower Reserve: Approximately 72 hours\u003c\/p\u003e\n\u003cp\u003eCase Material: 18K white gold\u003c\/p\u003e\n\u003cp\u003eCase Size: Approximately 43.5 mm\u003c\/p\u003e\n\u003cp\u003eWater Resistance: Factory-rated to approximately 30 m\u003c\/p\u003e\n\u003cp\u003eDial: Dark dial with an open double-tourbillon display\u003c\/p\u003e\n\u003cp\u003eHour Markers: Applied Roman numerals and baton indexes\u003c\/p\u003e\n\u003cp\u003eFunctions: Hours, minutes, small seconds, power-reserve indication, and Double Tourbillon 30°\u003c\/p\u003e\n\u003cp\u003eInner Tourbillon: Inclined at 30 degrees with a one-minute rotation\u003c\/p\u003e\n\u003cp\u003eOuter Tourbillon: Four-minute rotation\u003c\/p\u003e\n\u003cp\u003eCrystal: Sapphire crystal\u003c\/p\u003e\n\u003cp\u003eCaseback: Sapphire exhibition caseback\u003c\/p\u003e\n\u003cp\u003eStrap: Black Greubel Forsey leather strap\u003c\/p\u003e\n\u003cp\u003eBuckle: Signed 18K white-gold pin buckle\u003c\/p\u003e\n\u003cp\u003eCondition: Preowned, Mint condition\u003c\/p\u003e\n\u003cp\u003eGender: Men’s\u003c\/p\u003e","brand":"Worldofluxuryus","offers":[{"title":"Default Title","offer_id":53992574222654,"sku":"Preowned-GF02","price":270000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/6522\/5790\/files\/IMG_2336.jpg?v=1785444251","url":"https:\/\/worldofluxuryus.com\/products\/greubel-forsey-double-tourbillon-30-vision-18k-white-gold-men-s-watch","provider":"Worldofluxuryus","version":"1.0","type":"link"}
