The Jacob & Co. Astronomia Solar is the latest version of the Astronomical Tourbillon, one of the most talked about watches at Baselworld 2014. The Wall Street Journal’s Michael Clerizo called it one of his three favorite watch exhibitions, and that a company primarily known for its fine jewelry timepieces has created such a complex mechanism, and something visually spectacular, This leaves a lot of people dizzy and tongue wagging. Granted, this isn’t Jacob & Co.’s first high-end mechanical complication, but it’s certainly the most stunning from a design standpoint, and it’s certainly captured the collective imagination of the fashion watch world. A lot of companies love this truly otherworldly, minimalist, blazing watch design,

Since the launch of the first model, the design has continued to evolve. One of the most interesting models is Astronomia Sky, which includes a sidereal time indication and star map.

The latest version of Astronomia is Astronomia Solar. The Solar differs from other Astronomia watches in many ways. The first one you might notice is that the central carrier has three arms instead of four. The time is displayed on a dial (mounted on a differential gear system that ensures 12:00 is always on top to make the time easier to read), the tourbillon is on the second carrying arm; the globe representing the earth is on the third arm . The center of the carrier is a 1.5 carat citrine with 288 facets.
