Roger Dubuis Much More Perpetual Calendar

About this reference

The Roger Dubuis Much More Perpetual Calendar reference M3457390 was produced during the late 1990s and early 2000s, an era defined by the founder’s direct involvement. Collectors prioritize this reference for its 18k white gold cambered rectangular case and the caliber RD5739, which carries the Geneva Seal. The dial features oversized Roman numerals and a four-register layout displaying day, date, month, and moon phase, with a leap year indicator integrated into the month sub-dial. This model belongs to a limited series of 28 pieces, a production cap standard for early Roger Dubuis complications. On the secondary market, this reference typically trades between $15,000 and $22,000 depending on condition and the presence of original documentation. A notable production detail is the inclusion of a solid case back alongside an interchangeable sapphire display back, allowing owners to view the hand-finished movement.
