Combining traditional craftsmanship with modern technology, the stone dial is a work of art in its own right. Starting with the finest raw material, the piece of stone is done precisely cut to obtain the right shape and thickness, then finally polished by hand to bring out its natural beauty.
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.
