Collectors prioritize this reference for its caliber GF02 movement, which features an inner tourbillon inclined at 30° rotating every minute inside an outer cage rotating every four minutes. The 43.5mm platinum case houses a dial characterized by three-dimensional gold plates engraved with the brand’s philosophy, a power reserve indicator, and a distinctive sub-seconds sapphire disk. This specific edition marked the transition of the Double Tourbillon 30° from a prototype concept to a retired historical pillar. On the secondary market, these timepieces typically command prices between $250,000 and $350,000. A notable auction result occurred in 2021 when a platinum Edition Historique sold for approximately $275,000, reflecting its status as a low-volume technical benchmark."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "greubel-forsey-gf02e-2025", "brand": "Greubel Forsey", "reference": "GF02E", "model": "Double Tourbillon 30° Edition Historique", "case_material": "Platinum", "hammer_usd": 390600, "year_sold": 2025, "venue": "Christie's New York", "lot_summary": "A limited edition of 11 pieces created to commemorate the conclusion of the Double Tourbillon 30° line, featuring signature engraved plates.", "source_url": "https://www.christies.com/en/lot/lot-6483895", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/greubel-forsey-gf02e-2025"}, {"slug": "greubel-forsey-gf02e-2022", "brand": "Greubel Forsey", "reference": "GF02E", "model": "Double Tourbillon 30° Edition Historique", "case_material": "Platinum", "hammer_usd": 311220, "year_sold": 2022, "venue": "Christie's Hong Kong", "lot_summary": "Features two engraved gold plates with the signatures of Robert Greubel and Stephen Forsey, celebrating the brand's first major invention.", "source_url": "https://www.christies.com/en/lot/lot-6398745", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/greubel-forsey-gf02e-2022"}, {"slug": "greubel-forsey-gf02e-pt-2025", "brand": "Greubel Forsey", "reference": "GF02E PT", "model": "Double Tourbillon 30°", "case_material": "Platinum", "hammer_usd": 267771, "year_sold": 2025, "venue": "Christie's Geneva", "lot_summary": "A platinum example of the brand's foundational invention, the 30° inclined double tourbillon, known for its award-winning chronometry.", "source_url": "https://www.christies.com/en/lot/lot-6483898", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/greubel-forsey-gf02e-pt-2025"}]}
