With the Heritage Perpetual Moon, H. Moser & Cie. is re-establishing the prestige of the most poetic complication ever: the representation of the lunar cycle. With its influence over the seas and the oceans, the lunar body holds a mysterious fascination for man. Showcased in a large window at 6 o’clock, the eye-catching moon elevates this model to an expression of classical watchmaking.
In addition to the moon phases, the Heritage Perpetual Moon features a small centre hand that serves as an AM/PM indicator, rotating once every 24 hours with the hour indices from 12 to 6 o’clock representing AM from midnight to midday and the left side of the dial representing PM from 1 pm to midnight. The moon phase display system is an extremely precise display that can be set, read and predicted to within a minute. The Heritage Perpetual Moon is one of the most precise moon phases available, with just one day’s deviation in every 1027 years.

Heritage Perpetual Moon
Drawing inspiration from H. Moser pocket watches, cases in the Heritage collection are rounded with refined accents that complement the engraving and blue enamel on the case flanks. Honouring tradition and craftsmanship, this decoration is a feature of Heritage collection models. The distinctive classicism of the Heritage Perpetual Moon is evident in the notched crown and "Grand Feu" enamel dial, enlivened by the hand-painted Roman numerals and the flame-blued swallow-tail hands.
