On the ground in the @jacobandco Astronomia Sky 🌌 Where high watchmaking meets astronomy: The #AstronomiaSky introduces astronomical complications into the extremely complex world of Astronomia. Apart from the day-night indication that works as a shield around the globe in the center of the dial, these features are implemented on the Celestial Dial that is spread out behind the four rotating arms. #jacobandco #jacobandcowatches #astronomia #rollsroyce #hautetime
