The Streamliner Tourbillon in red gold takes on a mineral makeover. The dial is crafted from a very rare form of green jade stone, known as Wyoming jade. Untreated, the Wyoming Jade stands out for its visual purity and deep olive tone. Containing subtle, naturally occurring marks and unique shades, the jade is worked with meticulous respect for its original structure, whose exceptional quality is revealed in its uniform composition of an almost immaculate purity. Void of any logo, the dial enhances the beauty of the double hairspring flying tourbillon standing out at 6 o’clock.

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.


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.
