This reference features a silver sunray dial with oversized black Roman numerals and a small seconds sub-dial at 6 o’clock. It is powered by the in-house Calibre RD620, an automatic movement featuring a micro-rotor and the Poinçon de Genève certification. Collectors value this model for providing the brand’s distinct aesthetic and high-level finishing in a versatile steel format that is now discontinued. On the secondary market, this reference typically trades between $6,000 and $9,000 depending on condition and the inclusion of original paperwork. While the Excalibur line is often associated with skeletonized tourbillons, the DBEX0354 remains a notable entry point for collectors seeking the brand’s hallmark micro-rotor technology in a traditional closed-dial configuration."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "roger-dubuis-dbex0354-2015", "brand": "Roger Dubuis", "reference": "DBEX0354", "model": "Excalibur 42", "case_material": "Stainless Steel", "hammer_usd": 26250, "year_sold": 2015, "venue": "Christie's Hong Kong", "lot_summary": "A fine stainless steel automatic wristwatch with a silvered brushed dial and Roman numerals, bearing the Geneva Seal.", "source_url": "https://www.christies.com/en/lot/lot-5953028", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/roger-dubuis-dbex0354-2015"}]}
