Collectors prioritize this reference for its rectangular cambered case and the Calibre RD57, an automatic movement bearing the Geneva Seal. The dial typically features oversized Roman or Arabic numerals and a railway minute track, reflecting the brand’s early neo-classical aesthetic. Production was strictly limited, often to 28 or 88 pieces per configuration, as indicated by the individual numbering engraved on the caseback. On the secondary market, these white gold models generally trade between $8,000 and $14,000 depending on condition and the presence of original documentation. A notable variant includes the \"Bulletin d'Observatoire\" editions, which were COSC-certified and featured a distinct movement finishing that commands a premium at international auction houses."},
