Collectors prioritize this reference for its 41mm stainless steel \"Big Eye\" case and the manual-wind Venus 178 movement, which features a specialized fourth sub-dial at twelve o'clock for tracking a second time zone. The dial is characterized by a reverse panda configuration with tritium luminous plots and a rotating external 24-hour bezel. This reference represents the final evolution of the vintage Aero-Compax line before the brand's decline during the quartz crisis. On the secondary market, prices typically range from $15,000 to $25,000 depending on the preservation of the bezel and dial patina. A notable production detail is the \"MK1\" variant, which features a distinct red 24-hour hand, often commanding a premium at specialized timepiece auctions."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "universal-gen-ve-890101-01-2018", "brand": "Universal Genève", "reference": "890101/01", "model": "Aero-Compax", "case_material": "Stainless Steel", "hammer_usd": 10700, "year_sold": 2018, "venue": "Sotheby's New York", "lot_summary": "A rare 1960s Aero-Compax featuring a 24-hour dial and a rotating 24-hour bezel for tracking a second time zone.", "source_url": "https://www.sothebys.com/en/auctions/ecatalogue/2018/important-watches-n09879/lot.293.html", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/universal-gen-ve-890101-01-2018"}]}
