dive into the technical specifications
The HMC 804 is an automatic tourbillon movement which counteracts the effects of gravity in two ways: the one-minute flying tourbillon, and the patented double hairspring where two identical hairsprings compensate for any positional errors.
Conceived to counteract the effects of gravity on the watch’s timekeeping precision, the tourbillon is a device in which the regulating organ and escapement are placed, which constantly rotates around a central axis to eliminate any positional errors.
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.
"Both the double hairspring and the Tourbillon work to balance out the force of gravity. It’s an incredibly accurate watch."
Stephan Christ, Head of Hairspring Production (Precision Engineering)
