A model that symbolizes two cultures coming together.

The rich dials of Parmigiani Fleurier's Tonda PF Xiali Calendar and Blancpain's Villeret Traditional Chinese Calendar have now been joined by a new model dedicated to the Chinese calendar by H.  Moser & Cie., which looks surprisingly minimalistic.

This is all the more impressive when you consider the fact that it combines the complicated Chinese system of measuring time with the Gregorian calendar.

The familiar European solar calendar is accommodated in a date aperture at 6 o'clock. The remaining indications are all connected to the Chinese system.

One of its main features is the appearance of a thirteenth month, which is added every two or three years. The need for the addition of this "embolismic" month has to do with the differing lengths of lunar and solar cycles.

The thirteenth month on the Endeavour Chinese Calendar Limited Edition model is displayed in an aperture at 12 o'clock, along with the Chinese lunar year and the corresponding zodiac sign. This aperture stays black in a twelve-month year.

The lunisolar month appears in the crescent-shaped aperture to the left, while lunisolar days and moon phases are displayed in a symmetrical window to the right. Both indications use retrograde hands.

The movement for this complicated novelty by H.  Moser & Cie. was developed by the partner company Agenhor SA, creators of the famous AgenGraphe chronograph movement. H.  Moser & Cie. use it in their Streamliner collection.

It's configured so that watchmakers only need to intervene once every twelve years to correct readings. This can be conveniently timed to coincide with routine watch servicing. The automatic caliber HMC 210 movement has a three-day power reserve and is equipped with a gold rotor.

Once again, H. Moser & Cie. have left the deep Midnight Blue fumé dial without a conspicuous logo: it's been applied with transparent lacquer and is almost invisible. The deep tone used for the dial is the perfect match for the red-gold 40-mm case. Availability of the watch is limited to a series of 100 pieces.
