Given the acclaim for its perpetual calendar, the most legible and ingenious on the market, H. Moser & Cie. wanted to explore this complication further and add another calendar to its collection. In collaboration with its partner, Agenhor SA, H. Moser & Cie. developed the Endeavour Chinese Calendar Limited Edition, produced in 100 pieces. This timepiece is a real technical feat, combining the Chinese lunisolar calendar with the solar-only Gregorian calendar and displaying the 12 signs of the Chinese zodiac alongside the moon phases, all without requiring any corrections for 12 years. It also symbolises the union of two different cultures and measurements, and their harmonious coexistence. The timepiece unites the sun and moon, combining elements of the solar and lunar calendars, calculated separately, and synchronising them.
