The new Jacob & Co. Astronomia Maestro Worldtime is the brand's most complicated and spectacular timepiece
Jacob & Co. has expanded its collection of ultra-exclusive timepieces handcrafted by Astronomia with another sculptural masterpiece as an ode to space exploration. The new limited-edition Jacob & Co. Astronomia Maestro Worldtime features all the iconic elements that define the collection plus two new additions - the world time complication and the Carillon minute repeater. Described as one of the most complex astronomical collections ever produced by the Haute Horlogerie brand, the new timepiece pushes the boundaries of horological engineering and craftsmanship.
Start with the large 3D case housing the watch's complications, which measures 50mm wide and 26mm thick. The skeletal construction of the 18K rose gold case is designed to showcase the exquisite movement and other components with minimal hindrance. It also lacks a traditional crown due to the unconventional design of the case, which is basically a cylindrical sapphire case with a gold chassis. Instead, the winding and setting mechanisms can be found on the solid caseback.
Moving to the skeletonized dial of the timepiece, the horological dance of the different parts is simply jaw-dropping. Unlike previous Astronomia watches, the main chronograph dial of the latest version is not placed on one of the movement's signature stacked track arms. In the new Astronomia Maestro Worldtime edition, the dial is right in the center, placed on top of the center stack for easy reading. The domed chronograph dial features contrasting traditional blue alpha hands and an engraved chemin-de-fer minute track with Arabic numerals.
Featuring the brand's signature Jacob Cut 1-carat spherical diamond that rotates around its axis every 90 seconds, this features a three-axis tourbillon in its stylized frame with the Jacob & Co. rose gold logo . There is also a highly detailed image of an orbiting astronaut on the other end of the spherical diamond, hand-painted in German silver. The highlight of the new Astronomy is its orbital world timer complication. The large painted rose gold globe rotates on its axis every 24 hours, indicating the time in each of the 24 time zones with a set of fixed indicators at the south pole.
Equipped with the in-house JCFM11A hand-wound minute repeater tourbillon movement, the watch offers a power reserve of 50 hours, as stunning as a timepiece. The watch is worn on a classic navy blue alligator leather strap with an 18K rose gold deployant clasp.
