This reference is characterized by its 34.5mm to 35mm staybrite stainless steel case featuring a snap-on back and square chronograph pushers. Collectors prioritize this model for its use of the in-house caliber 285, a manual-wind column-wheel movement, and its \"Compur\" nomenclature, which signifies a dual-register layout. Dial variations often include multi-scale configurations with tachymeter and telemeter tracks in various colors. On the secondary market, examples typically trade between $4,000 and $8,000 depending on dial originality and case sharpness. A notable production detail is the \"Enversteel\" branding found on some casebacks, a proprietary stainless steel alloy used by the manufacture during this era. High-condition examples with rare \"tropical\" or black dials have occasionally exceeded these price brackets at specialized watch auctions."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "universal-gen-ve-22409-2016", "brand": "Universal Genève", "reference": "22409", "model": "Compur 30", "case_material": "Stainless Steel", "hammer_usd": 12800, "year_sold": 2016, "venue": "Christie's Geneva", "lot_summary": "A fine stainless steel chronograph with a black military-style dial, manufactured in 1941.", "source_url": "https://www.christies.com/lot/lot-universal-a-fine-and-extremely-attractive-stainless-6034440/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/universal-gen-ve-22409-2016"}]}
