Collectors prioritize this reference for its Valjoux 72C movement, a column-wheel caliber integrated with a full calendar complication. The 35mm stainless steel case features the brand's signature coin-edge fluting on the mid-case and downturned lugs. The dial typically displays a date scale on the outer periphery indicated by a central pointer hand, with day and month apertures positioned below twelve o'clock. Due to the limited production numbers of steel Breguet chronographs from this era, examples are rare. On the secondary market, these watches generally command prices in the $40,000 to $70,000 range depending on condition and provenance. A notable example appeared at a 2016 Christie’s auction, where a well-preserved steel 586 realized approximately $62,500."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "breguet-586-2018", "brand": "Breguet", "reference": "586", "model": "Triple Calendar Chronograph", "case_material": "Stainless Steel", "hammer_usd": 162500, "year_sold": 2018, "venue": "Phillips Geneva", "lot_summary": "An extremely rare stainless steel complication from 1972, featuring a Valjoux 88 movement and a design reminiscent of the Patek Philippe 1518.", "source_url": "https://www.phillips.com/detail/breguet/CH080118/231", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/breguet-586-2018"}]}
