DESCRIPTION:
When the Astronomia Tourbillon was introduced in 2014, the re-invention of the tourbillon in a vertical orientation and the constant turning of its four satellites garnered most of the attention.
What led to the development of the Astronomia Art Collection, however, is the incredible sapphire crystal and precious metal case, which puts everything on display.
- 3-D 18K hand-engraved gold dragon.
- Iconic gravitational double-axis tourbillon.
- 288-facet Jacob-cut diamond turning in 30 seconds.
- Magnesium globe turning in 30 seconds.
- Domed and curved, anti-reflective sapphire crystal.
