This reference is valued for its RD5739 movement, which carries the Geneva Seal and features a perpetual calendar with a moon phase indicator. The 34mm case utilizes a stepped bezel and concave lugs, housing a silvered dial with applied Roman numerals and leaf-shaped hands. Production was strictly limited, often to 28 pieces per metal, making it a rare example of early independent watchmaking. On the secondary market, this reference typically trades between $15,000 and $25,000 depending on condition and the presence of original accessories. A notable production detail is that these early movements were often based on Lemania blanks but finished to chronometer standards, as evidenced by the \"Bulletin d'Observatoire\" certification frequently noted on the dial."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "roger-dubuis-h3457395-2024", "brand": "Roger Dubuis", "reference": "H3457395", "model": "Hommage Quantieme Perpetual", "case_material": "18k Pink Gold", "hammer_usd": 21080, "year_sold": 2024, "venue": "Christie's Hong Kong", "lot_summary": "A rare limited edition automatic perpetual calendar with moon phases and leap year indication, numbered 9 of 28.", "source_url": "https://www.christies.com/en/lot/lot-6499398", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/roger-dubuis-h3457395-2024"}]}
