Collectors target this 45mm 18k white gold model for the RD01 manual-wind movement, which features two differential-linked flying tourbillons and carries the Poinçon de Genève. The dial is characterized by oversized Roman numerals and a skeletonized view of the escapements. This reference represents the brand’s transition into high-complication technical aesthetics under the original vision of Roger Dubuis. On the secondary market, this specific white gold model typically trades in the $60,000 to $90,000 range, depending on provenance and service history. A notable production detail is that this reference was often limited to 28 pieces globally, a common restriction for the brand's high-complication white gold variants during that era, ensuring relative scarcity compared to later mass-produced iterations.", "score": 199}, {"slug": "roger-dubuis-ex45-01sq-20-00", "brand": "Roger Dubuis", "ref": "EX45-01SQ-20-00", "model": "Excalibur Double Tourbillon Squelette", "case_material": "18k White Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/roger-dubuis-ex45-01sq-20-00", "description": "The Roger Dubuis Excalibur Double Tourbillon Squelette reference EX45-01SQ-20-00 was introduced around 2009 and is no longer in current production. Collectors target this reference for its 45mm 18k white gold case and the caliber RD01SQ, a hand-wound movement featuring two differential-linked flying tourbillons. This model represents the brand’s transition toward its signature \"Astral Skeleton\" design language, characterized by star-shaped bridges and the Poinçon de Genève certification visible on the movement components. The production was limited to 28 pieces, making it a rare find compared to later non-limited iterations. On the secondary market, this specific reference typically commands prices in the $120,000 to $160,000 range depending on provenance and service history. A notable auction result occurred in 2016 when a similar white gold example achieved approximately $130,000, confirming the sustained value of these early, low-volume skeletonized complications.", "score": 84}]}
