This model features a 42mm 18k white gold case characterized by the collection's signature triple lugs and notched bezel. It is powered by the manufacture Calibre RD77, an automatic movement featuring a micro-rotor and 42 hours of power reserve. The dial utilizes a silvered finish with oversized black Roman numerals and a small seconds sub-dial at 9 o'clock. Collectors value this reference for its integration of traditional Geneva seal finishing within a bold, contemporary design language. On the secondary market, this model typically trades between $10,000 and $15,000 depending on condition and the presence of original documentation. A notable production detail is the limited run of 888 pieces, a common numbering convention for the brand during this era."}, "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.
