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.


Bringing light to darkness, Super-LumiNova® is a photo-luminescent pigment used on different elements. After being charged by light, it emits a glow that makes the reading of time possible even when it’s pitch black.
