The Jacob & Co. Astronomia Clarity

The Astronomia Clarity Rose Gold features a 50mm case made almost entirely of sapphire crystal with 18K rose gold frame and lugs. This provides the clearest view yet of the iconic Astronomia four-arm vertical movement and its four exclusive complications, which revolve within the case every 20 minutes: The patented triple-axis gravitational tourbillon, the time display subdial with the patented differential system, the rotating exclusive Jacob Cut diamond with 288 facets, and the rotating magnesium and lacquered globe. #jacobandco #inspiredbytheimpossible #hautehorology
