Luna Nera is a superb achievement combining the typical technology of vertical capstan wheels, fusée-and-chain system, with a sumptuous moon phase in 3-dimensions. The sapphire crystal in giant screen, which represents a large window facing the sky, allows observing the mechanism of the watch and more particularly the 3D moon, as do astronomers from their observatories.
This exceptional piece is composed of a manually wound movement: caliber CAB EC 102L, with 46 rubies. The mechanism indicates the hours, minutes, seconds and power reserve by drums, one characteristic of this collection. The moon phase, meanwhile, is at the center of the movement and is represented by a sphere of 7.40 mm diameter.
The torque is transmitted from the drum barrel to the fuse via a chain. This concept allows a constant torque transmission throughout the power reserve (72 hours), ensuring greater accuracy in the measurement of time.
The regulating component is composed of a tourbillon with a balance spring which has a frequency of 3Hz making one rotation per minute. The winding and time setting are manually adjusted by two distinct crowns, a third one allows the setting of the moon.
