Astronomia Tourbillon

A solar system orbiting under a sapphire dome.

Ref. AT100.30.AD.SD.A · Released 2014 · Switzerland

The Astronomia abandons the flat dial entirely: four arms carry a triple-axis tourbillon, a rotating time display, a magnesium globe and a Jacob-cut diamond around a central differential.

Reading the time requires the display arm to swing into view — a deliberate rejection of at-a-glance legibility in favour of spectacle.
