This reference features the manual-wind caliber RM018, a tourbillon movement distinguished by its use of semi-precious and precious stones, such as tiger’s eye, jasper, and onyx, for the movement wheels. The 18k white gold case measures 48mm by 39.3mm and houses a transparent synthetic sapphire baseplate. Collectors value this reference for its technical integration of high jewelry materials into a mechanical movement and its rarity within the brand’s early production history. On the secondary market, the RM018 typically commands prices in the mid-to-high six-figure range, often exceeding $500,000 depending on the specific stone configuration. A notable auction result occurred in 2022 when a white gold example sold for approximately $750,000.", "score": 200}]}
