A decade after revolutionising haute horlogerie, Jacob & Co. has unveiled its most audacious creation yet. The Astronomia Revolution Fourth Dimension pushes the boundaries of what is possible within luxury watchmaking by adding an unprecedented fourth axis to the tourbillon mechanism.
The journey began in 2015 when the original Astronomia Tourbillon stunned the industry with a movement that completed a full rotation every 20 minutes, an engineering milestone encased within a dramatic 360-degree display. Subsequent evolutions accelerated this rotation to 10 minutes, and in 2023, the Astronomia Revolution achieved an extraordinary 60-second revolution of its complex tourbillon system.
Jacob & Co.’s latest creation exhibits a complete reimagining of movement architecture. Whilst traditional tourbillons operate across three axes of rotation, the brand’s engineers have successfully integrated a fourth rotational plane, requiring complete recalibration of weight distribution and gear train mechanics, resulting in a triumph of high watchmaking.
Retaining the collection’s signature orbital display, the new Astronomia introduces a heightened level of complexity. Each component moves along a precisely engineered path, sustaining perpetual motion within a finely tuned movement. Sapphire crystal cases offer unobstructed views of the movement’s structural depth, while select models incorporate sculptural elements from miniature celestial bodies to emblematic figures, each executed with exceptional detail.
Encased in 47mm of 18K rose gold and sapphire, the Fourth Dimension transforms timekeeping into kinetic art. Its mirror-polished gold-plated backplate features a striking geometric mosaic, with each element meticulously crafted and positioned to catch and reflect light. Rather than traditional gem settings, rose gold elements are arranged in an unexpected inverted layout, creating captivating optical effects.
“Celebrating the 10th Anniversary of the Astronomia is a major milestone in the history of Jacob & Co. Just as the Five Time Zone put us on the watchmaking map in 2002, the arrival of the Astronomia in 2015 elevated us to the innovative fringe of high watchmaking, exemplifying what it truly means to be ‘Inspired by the Impossible.’ It set us on an endlessly upward trajectory, reaching for the unreachable.” Jacob Arabo – Chairman and Founder of Jacob & Co.
From exquisite sapphire cases to sculptural forms inspired by mythical creatures, the Astronomia collection has continuously pushed the boundaries of haute horology. It places kinetic spectacle at the heart of its design. Jacob & Co. embraces bold innovation that reimagines watchmaking as art, reflecting the visionary spirit that defines the most trailblazing luxury maisons.
The Fourth Dimension’s arrival coincides perfectly with the collection’s anniversary, marking a decade of boundary-breaking innovation.The Astronomia Revolution Fourth Dimension reflects Jacob & Co.’s ongoing commitment to pushing the limits of watchmaking.
