Perpetual Calendar


HMC 800

In shades of anthracite and blue, this Endeavour Perpetual Calendar revisits H. Moser & Cie.’s emblematic complication in a visually striking manner. Combining tantalum, a stable and durable metal with a unique hue that’s exceedingly difficult to machine and polish with the ancestral technique of “grand feu” enamelling, a new dimension of vibrant colours and textures embellish world’s most intuitive and legible perpetual calendar watch.

The HMC 800 is a uniquely simple and award-winning manual-winding Perpetual Calendar movement, where the calendar mechanism is an integral part of the movement rather than a modular add-on.


Rather than inundate the dial with windows, this perpetual calendar uses a small arrow and the 12 indices to represent the month. Additionally, the date and month can be set forwards or backwards at any time, without risk to the movement.


Lending a new dynamic to the traditional art form of enamelling with the use of a pattern engrained, as if hammered, onto a gold base and three different colour pigments that are melded together. The result is a textured and immaculate fumé aesthetic for a captivatingly contemporary finish.
