This reference is technically significant as the brand’s first serially produced split-seconds perpetual calendar, housing the manual-wind Caliber CHR 27-70 Q based on a Lemania ébauche. Collectors prioritize this model for its 36.7mm case proportions and the complexity of its split-seconds mechanism, which required a specific isolator system to prevent drag. Total production across all metals is estimated at approximately 12 units per year, making the pink gold execution relatively scarce. On the secondary market, the 5004R typically trades in the $250,000 to $350,000 range depending on provenance and the presence of the original second solid caseback.

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.

The 40mm case utilizes the signature Fleurier \"bow\" at twelve o'clock, mimicking 19th-century pocket watches, while the dial often features white lacquer or guilloché finishes with blued steel screws and hands.
