Along with the sunburst pattern and gradient colour effect of the fumé dial, this concept model takes a minimalistic approach by foregoing the logo and all other markings from the watch face.
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.
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.
