{"product_id":"greubel-forsey-double-tourbillon-30-technique-black","title":"Greubel Forsey Double Tourbillon 30° Technique Black","description":"\u003cp\u003eThe Greubel Forsey Double Tourbillon 30° Technique is one of the most sophisticated mechanical achievements in contemporary watchmaking. Invented by Robert Greubel and Stephen Forsey to maximise tourbillon efficiency, the patented system features two tourbillon cages — an inner 24-second tourbillon inclined at 30° rotating inside a larger 4-minute outer cage — working in concert to counter the effects of gravity across all positions. This black edition pairs an ADLC-coated titanium case with a skeletonised dial revealing the full depth of the movement, finished on a black rubber strap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e Double Tourbillon 30° Technique Black\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Pre-Owned\u003cbr\u003e\u003cstrong\u003eCase Material:\u003c\/strong\u003e Titanium with ADLC coating\u003cbr\u003e\u003cstrong\u003eDial:\u003c\/strong\u003e Skeletonised, black\u003cbr\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Manual-winding, double tourbillon with 30° inclination, 4-minute outer cage, 24-second inner cage; 72-hour power reserve\u003cbr\u003e\u003cstrong\u003eBracelet\/Strap:\u003c\/strong\u003e Black rubber strap\u003cbr\u003e\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 30m\u003c\/p\u003e\u003cp\u003eAvailable at LuxurySouq — Dubai's trusted destination for certified pre-owned luxury timepieces.
