This manual-wind caliber features a rattrapante function, allowing for the timing of two simultaneous events. The dial typically features a 24-hour scale or a standard 12-hour layout with Arabic numerals and the retailer’s name. Due to a limited production run estimated at fewer than 100 units, the reference is rare. Current secondary market values generally fall within the mid-to-high six-figure range. A notable auction result occurred in 2016 when a well-preserved example sold for over $300,000, reflecting the high demand for steel-cased military chronographs with complex complications."}, "score": 15, "why_compare": "Shared search intent: cairelli, chronograph; similar steel case profile.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 2, "review_url": "https://mostexpensivewatches.net/ja/review/universal-gen-ve-22560", "alternatives_url": "https://mostexpensivewatches.net/ja/alternatives/universal-gen-ve-22560"}, {"reference": {"slug": "audemars-piguet-1533", "brand": "Audemars Piguet", "ref": "1533", "model": "Oversized Chronograph", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/audemars-piguet-1533", "description": "The Audemars Piguet Reference 1533 was produced in the early 1940s, with approximately nine units manufactured between 1941 and 1943.
