This reference is distinguished by its white dial and white registers, a departure from the standard \"Siffert\" model which features black sub-dials. It utilizes the Calibre 12 automatic chronograph movement housed in a 42mm stainless steel cushion case with a notched bezel. Collectors value this variant due to its extreme rarity; it is estimated that fewer than ten authentic examples are publicly known to exist. Because of this scarcity, secondary market prices typically occupy the high-five-figure to low-six-figure range depending on condition and provenance. A notable auction result occurred in 2017 at the Heuer Parade sale, where an example achieved a hammer price of approximately 81,250 CHF. Verification of the serial number range, typically around 242xxx, is a critical factor for collectors evaluating the authenticity of this specific execution."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "heuer-1163t-2022", "brand": "Heuer", "reference": "1163T", "model": "Autavia \"Jo Siffert\" Albino", "case_material": "Stainless Steel", "hammer_usd": 12342, "year_sold": 2022, "venue": "Bonhams London", "lot_summary": "A rare variation of the 'Jo Siffert' Autavia featuring white 'Albino' hands with blue tips, from the Gentleman of Motorsports collection.", "source_url": "https://www.bonhams.com/auctions/27665/lot/51/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/heuer-1163t-2022"}]}
