Collectors prioritize this reference for its use of the Calibre 11 and Calibre 12 movements, which feature a distinctive left-hand crown and right-hand pushers. The 42mm stainless steel case utilizes a tonneau shape with a rotating bezel and 20mm lugs. Key valuation factors include the presence of the \"Chrono-Matic\" dial text on early examples and the specific configuration of the fluted pushers. On the secondary market, prices typically range from $5,000 to $15,000 depending on condition and specific execution. A notable variant is the 1163 \"Jo Siffert,\" characterized by a white dial with blue accents and black registers, which frequently commands a significant premium at auction due to its association with the Swiss Formula One driver.", "score": 199}, {"slug": "heuer-1163t", "brand": "Heuer", "ref": "1163T", "model": "Autavia Albino", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/heuer-1163t", "description": "The Heuer Autavia 1163T \"Albino\" was produced for a brief period around 1971. 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.", "score": 84}]}
