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": 1, "median": 10950.0, "low": 10950.0, "high": 10950.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_14785663467903", "title": "Roger Dubuis Roger Dubuis Excalibur | REF.
