HMC 800

An ingenious and award-winning take on one of the most complex complications in watchmaking, the Endeavour Perpetual Calendar in white gold and Cosmic Green fumé dial applies H. Moser & Cie.’s less is more philosophy. By using the existing 12 indices to indicate the month, the beauty of the dial is left in the focal point while the month can be intuitively “read” at a glance.

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.


Along with the sunburst pattern and gradient colour effect of the fumé dial, this purity model takes a purist approach by only incorporating the four cardinal indices on the watch face – at 3, 6, 9 and 12 o’clock.
