H. Moser & Cie Perpetual Moon

About this reference

The H. Moser & Cie. Endeavour Perpetual Moon reference 1348-0100 was introduced around 2010 and remained a core offering in the brand’s catalog for approximately a decade before being superseded by the Vantablack and Concept iterations. This reference features a 40.8mm case in 18k pink gold and is valued for the hand-wound caliber HMC 348, which incorporates a modular escapement and a moon phase complication accurate to one day every 1,027 years. The dial is characterized by a fumé finish and a large moon phase aperture at 6 o'clock, utilizing a disc that tracks the lunar cycle with high precision. On the secondary market, this reference typically trades between $18,000 and $25,000 depending on condition and completeness. A notable production detail is the inclusion of a discrete AM/PM indicator at the center of the dial, which is adjusted via the crown to ensure the moon phase remains synchronized.
