The complicated marriage of the Chinese and Gregorian Calendars is tackled by H. Moser &amp; Cie.

Building on the success of its perpetual calendar, celebrated as the most intuitive and cleverly designed on the market, H. Moser &amp; Cie. sought to expand its horological repertoire by adding another complex calendar type to its collection. In partnership with Agenhor SA, the company created the 100-piece Endeavour Chinese Calendar Limited Edition. This watch marries the Chinese lunisolar calendar with the Gregorian calendar and presents the twelve Chinese zodiac signs and moon phases, all while eliminating the need for any manual adjustments for a full twelve years. This is a technological marvel that also represents the seamless blend of two distinct cultures and timekeeping systems. The watch is a symbol of the harmonious blend of solar and lunar timekeeping traditions, executed with elegance, despite its inherent complexity.

The Endeavour Chinese Calendar Limited showcases an array of displays including the Chinese and Gregorian calendar days, moon phases, and the Chinese zodiac signs. While in typical lunar calendars, there is a seasonal drift when each month begins roughly eleven days earlier each solar year, lunisolar calendars incorporate an "embolismic" month every two to three years to align with the solar calendar. Considering that the Chinese calendar is characterised by its lack of repetitive cycles, the creation of a perpetual Chinese calendar is normally considered mechanically unfeasible. To counter this, H. Moser &amp; Cie. and Agenhor SA, took on the significant task of engineering a watch capable of accurately displaying all lunisolar calendar details over the 12-year cycle without any adjustments. The groundbreaking automatic HMC 210 calibre created by the two entities autonomously tracks the varying number of Chinese lunisolar months, their length, the embolismic months, the zodiac year, moon phases, and Gregorian dates for an entire 12-year cycle.

Through the HMC 210 concealed behind the signature Midnight Blue fum&eacute; dial, the watch displays the Chinese lunisolar months on the left side of the dial. Meanwhile, on the right, the Chinese lunisolar days and moon phases is shown. Both of these indications are made through crescent-shaped openings on the respective sides, indicated by two retrograde hands that reset after each cycle. At the top of the dial, the aperture reveals the Chinese lunisolar year and its corresponding zodiac animal, along with the leap month number in a 13-month year; in a regular 12-month year, this space remains empty. Additionally, there's a small-seconds counter layered over the Gregorian calendar at 6 o'clock.
Edouard Meylan, CEO of H. Moser &amp; Cie., explains, "This synergy between our two partner companies gave rise to the Endeavour Chinese Calendar Limited Edition, which conveys the complexity of the Chinese calendar and encapsulates it in an elegant and refined watch that is easy to use, read and adjust. With its minimalist and elegant aesthetics, it is a contemporary westernized interpretation of the Chinese traditional culture, unlike the other models of its kind available on the market, which are extremely complex in functional display, difficult to read, and have a very oriental design. I am convinced that this piece's success will transcend borders and cultures simply because it is a beautiful thing."
