Anniversary four-axis tourbillon in rose gold.

This year's Watches and Wonders trade show coincides with a wealth of anniversaries: Vacheron Constantin's 270th anniversary, Zenith's 160th anniversary, the 30th anniversary of Roger Dubuis, the 70th anniversary of IWC's Ingenieur model, and the 25th anniversary of Chopard's L.U.C Quattro technology…

Against the backdrop of these big dates, the tenth anniversary of the Astronomia collection by Jacob & Co. doesn't look like such a big deal. But this certainly can't be said of the watches themselves or the role they've played in the brand's history. A day ahead of the watch industry's main trade show in the calendar, journalists were invited to celebrate and see the anniversary novelty: the Astronomia Revolution Four-Axis Tourbillon.

The first Astronomia was actually unveiled in 2013 and created a real sensation. The model revolutionized watch mechanics. The dial was transformed into a platform for the tourbillon carriage, which completed one full rotation every 20 minutes.

It had four Jacob-cut diamonds with 288 facets for satellites, a tourbillon, a subdial for the hours and minutes, along with a miniature globe. Luca Soprana's Studio 7h38 helped the company realize the brilliant idea.

Jacob & Co. already had impressive watches under their belt in the early 2010s, like the Ghost Five Time Zone model, the Quenttin Tourbillon with a month's worth of power reserve, and the SF24 with a large "split flap" display board for different time zones like ones you'd see at train stations. But Astronomia remains the most successful concept.

Skulls, figurines by Alec Monopoly, planets, a phoenix, and a miniature casino roulette — you name it: almost everything you can think of has spun around on this dial over the years. And it keeps getting faster.

The Astronomia Revolution was introduced in 2023, which sped the tourbillon carriage up to one revolution per minute, and it had a honeycomb array base dial inspired by the James Webb Space Telescope. This model was the starting point for the 2025 novelty.

The main technical difference in the Astronomia Revolution Four-Axis Tourbillon is the appearance of its four-axis tourbillon in the JCAM54 made with Concepto. Each axis rotates at its own pace: 60 seconds, 18 seconds, 15 seconds, and 60 seconds.

The honeycombs have also changed, which have been given more volume and now look more like faceted stones. Availability of the novelty is limited to 18 pieces in rose-gold cases measuring 47 mm × 27 mm.
