Each spiral ray is perfectly set with a single row of diamonds. The spray of diamonds emanating outwards in 14 rays from the tourbillon escapement at 6 o’clock can also be associated with the spiralling vortex one perceives in the Milky Way, or as an allusion to the whirlwind or tornado, or the spiral patterns of organic growth exhibited by certain sea creatures, plants, trees and animals.
BLACK ONYX BASEPLATE
Onyx is a variety of cryptocrystalline quartz chalcedony composed of silica dioxide (SiO2). The variety with rectilinear black and white parallel stripes is part of the agate family, whereas the fully black type is known as black onyx.
A gemstone thought to deflect and channel harmful energy towards the Earth, it provides stability. For this reason, black onyx is considered a stone of protection against negative thoughts, as well being the stone of equilibrium and inspiration.

This tripartite tonneau-shaped case is fully curved, which makes the watch ergonomic and comfortable, but is time consuming to produce and requires a high level of quality control.
The bezel and the caseback have to be perfectly assembled with the case middle to prevent damage to the sapphire crystals. Developing the requisite manufacturing specifications demanded an entire year of research and development.
The case is set with white diamonds, and black sapphires have been added to accentuate case details.
