It’s been ten years since Jacob & Co. first dropped the Astronomia collection and made the entire watch world stop and ask, “Wait, they can do that?” A decade later, they’ve answered that question with an even more absurdly ambitious follow-up: the Astronomia Revolution Four-Axis Tourbillon.
To mark the anniversary, Jacob & Co. could’ve just made a limited edition version of the original with some diamonds and called it a day. But of course, this is Jacob & Co. we’re talking about, the brand that’s made a habit of ignoring the rulebook in favor of doing whatever wild thing crosses their minds. And in this case, that means taking their now-iconic Astronomia and adding a fourth axis to the already mind-bending tourbillon setup. Yeah, four axes. Your Submariner is quaking.
This watch is what happens when haute horology becomes high-concept art. It’s impractical, over-the-top, and completely unnecessary, and that’s exactly why it’s great.

The Juice
Let’s start with the tourbillon, because that’s the headline here. The original Astronomia already played with multiple axes, but the Astronomia Revolution Four-Axis Tourbillon kicks it into a whole new dimension, literally. You’ve got four independent axes spinning at different rates: one every 60 seconds, one every 18, another every 15, and one more at 60 again. At the top of it all is a triple-axis flying tourbillon, which itself makes a full loop every 60 seconds. That’s just too complicated to comprehend.
To make it all run smoothly, Jacob & Co. has integrated a high-frequency constant force mechanism that ticks at 1/6th of a second, helping regulate the power and maintain consistent motion. It’s the kind of technical detail that usually lives in the shadows of simpler watches, but here it’s front and center.
Visually, this thing is as much sculpture as timepiece. The entire movement is mounted on a rotating carousel under a massive domed sapphire crystal, enclosed in a 47mm case made from rose gold and transparent sapphire. The mirror-polished, gold-plated backplate adds a little extra flash, featuring a geometric mosaic layout that catches and reflects light like a disco ball for the ultra-wealthy. Even the way the backplate is designed is unconventional. The gold shapes are inverted and set in a way that maximizes the way light hits them. You’re not just looking at a watch; you’re looking at a kinetic light show on your wrist.
Of course, telling the time here is borderline secondary. There is a small red composite dial with skeletonized hour and minute hands, but it feels like it’s only there because legally, this still has to count as a watch. No one’s buying this to check if they’re late to a meeting.
And yes, it’s $700,000. But this isn’t a flex piece for someone who wants to show off their wealth, it’s a statement for someone who wants to show off their taste in mechanical insanity. Only 18 will be made, which feels about right. There are maybe 18 people in the world who could pull this off.
Final Thoughts
The Astronomia Revolution Four-Axis Tourbillon isn’t for the faint of heart. It’s massive, it’s loud, and it doesn’t care one bit about conventional wisdom. But in a world full of safe designs and endless heritage reissues, it’s refreshing to see a brand that’s still pushing boundaries just because they can.
Ten years after the first Astronomia shook things up, Jacob & Co. is reminding everyone that they’re still the brand to beat when it comes to uncompromising, unapologetic watchmaking spectacle. The Revolution doesn’t just celebrate a decade of defying expectations. It doubles down on the chaos in the best way possible.
And hey, even if you’ll never wear one, it’s nice to know someone out there will. Find out more on Jacob & Co.’s website.
