Celestial bodies and space exploration have long driven Jacob Arabo's creativity. In 2014, he translated his intimate passion into an ambitious timepiece concept. Astronomia Tourbillon is an unheard-of translation of astrophysics into watchmaking form. It is a wrist-sized model of a planetary system and its constant motion. The Astronomia Tourbillon case is designed like an astronomer's observatory. A vast sapphire dome on top and sapphire panels on the caseband open a galaxy-wide view. The aventurine base plate shines like a starry sky at night. A diamond-made moon and a blue lacquer earth come alive with the combination of design and horology. Astronomia Tourbillon is pure movement, at a level of complexity and beauty that makes it unique.
